Publisher: 2013Dissertation note: 6.1 Background
Antimicrobial resistance is an under-appreciated threat to public health in nations around the globe. With globalization booming, it is important to understand international patterns of resistance. Thermotolerant Campylobacter spp. are considered to be the most frequent cause of human acute bacterial enteritis worldwide, furthermore, numerous transmission vehicles are known, but raw milk, untreated surface water and especially poultry meat are major sources of human infections. In Pakistan studies reveal that among meat samples, the highest prevalence (48%) of Campylobacter was recorded in raw chicken. Therefore, the increasing level of resistance to the antibiotics among Campylobacter spp. is recognized as emerging public health problem.
6.2 Hypothesis
" Campylobacter spp. was present in the poultry meat at retailer shops.
" Unhygienic measures concerning to meat handling had a considerable effect on the prevalence of antimicrobial resistant Campylobacter.
6.3 Methodology
A cross sectional study of 3 months duration was carried out in the Lahore city of Punjab, Pakistan. Using the standard microbiological techniques and statistical analysis, the prevalence of Campylobacter and its pattern of antibiotic resistance were evaluated. Furthermore, through premeditated questionnaires, public awareness regarding meat-borne diseases, food safety and inappropriate usage of antibiotics were assessed as well.
6.4 Statistical design
Data will be analyzed by using SPSS version 20.0. Quantitative variable were presented by using mean ± S.D. Qualitative variable were presented with help of frequency tables, pie charts and bar charts. Chi-square test was applied to see the association among different variables. P value <0.05 was be taken as significant.
6.5 Outcome
Through this cross-sectional study, the prevalence and pattern of the antibiotic resistant campylobacter was assessed; moreover public awareness with special reference to food safety, knowledge of meat borne diseases and usage of antibiotics wereevaluated. Furthermore, one could play an influential role in public health by dissemination of awareness among the masses about the proper usage of antibiotics and food safety measures.

Publisher: 2013Dissertation note: The term Designer egg has gained popularity all over the world. Egg which gives some health benefits with the provision of basic nutrients is called designer egg. Lutein a xanthophyll pigment is good for the prevention of age related macular degeneration (AMD).Egg is considered good vehicle for lutein transport as bio-availability of lutein is high through egg. The present study was aimed to produce lutein enriched eggs (designer eggs). Different sources of lutein were used and their effect on production performance and egg quality characteristics was measured. A total number of 432 Hy-line layers categorized into 3 body sizes (Heavy, Medium, Light) were offered 4 different supplementations of lutein (0, free, esterified, free + esterified) replicated 6 times having 6 layers each. Parameters regarding production performance, egg geometry and egg quality were observed.Data were analyzed according to Analysis of Variance (ANOVA) technique through Completely Randomized Design (CRD) using factorial arrangement. Means were compared through Duncan Multiple Range Test (Duncan, 1955) with the help of SAS 9.3. Results of the present study showed significantly higher Haugh unit score (87.17±0.39) in light birds during 3rd week whereas, within lutein sources significantly higher Haugh unit score was observed in layers fed with control diets (85.52±0.48). Significantly (p<0.05) higher yolk pH was observed in layers fed with esterified source of lutein whereas significantly higher (8.26±0.06) albumen pH was observed in birds fed with free source of lutein however, different body sizes could not show their effect on yolk and albumen pH. Significantly higher (62.97±0.22) albumen % was observed during 1st week of study in birds fed with esterified source of lutein whereas body weight categories did not affect the albumen% whereas,
yolk % was affected by different body sizes and lutein sources during 1st week of study. Significantly higher mean value (27.48±0.27) of yolk % was recorded in birds fed with combination of free and esters of lutein whereas higher value of yolk % (27.20±0.23) was observed in medium birds. Shell percentage significantly (p<0.05) affected by different body sizes (10.96±0.13) and lutein sources (11.14±0.18) during 1st week of study whereas shell thickness was significantly (p<0.05) affected by lutein sources (0.35±0.004) during 1st week of study. Means of different sources of lutein had significant (p<0.05) effect on yolk color and the highest mean value (11.63±0.15) was observed in birds fed with free source of lutein. Yolk index was significantly (0.36±0.005) affected by different lutein sources however, body sizes did not affect yolk index. As far as egg geometry was concerned egg surface area and egg volume were found to be significantly highest for heavy birds whereas non-significant differences for egg volume and shape index were observed. However, different lutein sources had no effect on egg geometry parameters. Significantly highest egg weight (62.74±0.23) was observed in heavy layers followed by medium (61.56±0.17) and light (60.63±0.17). However, different body weights (narrow ranges) and lutein sources had non-significant effect on production (%), FCR per dozen, egg mass and FCR per kg egg mass.

Publisher: 2013Dissertation note: In Pakistan poultry sector is playing a vital role in bridging the gap between supply and requirement of animal protein food for its ever increasing human population. The contribution of poultry sector in agriculture and livestock is about 6.4 and 11.5 percent, respectively (Anonymous, 2012). Poultry meat contributes about 25.8 percent of the total meat produced in the country. This sector has been growing at an annual rate of 8 to 10 percent, producing 131.4 million eggs and 0.834 million metric tons of poultry meat (Anonymous, 2012). However, despite this tremendous growth rate, this sector is facing many challenges which may badly influence its future pace of development. The most important of these is escalating cost of poultry feed which is considered to be the major cost item involving more than 60 to 70 percent share of production cost (Khan et al., 2010). Many of the traditional protein sources used in poultry diet formulations such as soybean, fish, sunflower meal and groundnut meal are becoming extremely expensive.
Rapid growth of human, livestock and poultry population has increased the demand for food and feed which has necessitated that alternative feed resource should be identified and evaluated. Therefore, the search for alternative protein sources has become urgent, and in this context, algae are worthy of consideration. The possibility of using fat-extracted algae (a by-product from bio-fuels production) as a source of protein and other nutrients in poultry feeds appears to be of great significance. The use of algae as a source of nutrients can benefit poultry and bio-fuel industry.
Diatoms are a major group of unicellular algae, and are one of the most common types of phytoplankton. They differ from other algae in the presence of substantial amounts of silicon in their cell membranes. The diatom, Nanofrustulum is currently under investigation as a potential source of oil for bio-fuel production. However, effect of dietary inclusion of defatted algae supplements by replacing soybean meal and corn on the performance of broilers has not yet been thoroughly investigated. The present study was therefore under taken at Poultry Research Farm, Department of Animal Science, University of Cornell, USA, to investigate effect of defatted algae Nanofrustulum meal on the growth performance, blood biochemical composition and gross pathology of tissues in broilers.
For this purpose, two levels of defatted algae Nanofrustulume 7.5 and 10 percent were used. Four different, iso-caloric and iso-nitrogenous experimental rations were prepared. The diet A was prepared without inclusion of algae (control), whereas in diets B and C the same algae at the rate of 7.5 percent were incorporated to replace soybean meal and soybean meal + corn, respectively. In diet D, algae at the rate of 10 percent replaced soybean meal and corn. Eighty, commercial (Ross), day-old, broiler chicks, 40 each of both sexes, were randomly divided into to 4 treatment groups (A, B, C and D) with two replicates each of 5 male and female birds per treatment. They were initially weighed and wing banded individually for identification and then maintained in thermostatically controlled battery cages. The birds were provided 22 hours light: 2 hours darkness schedule. All the experimental birds were fed a balanced broiler starter ration and water ad libitum until 21 days of age. All the experimental rations were supplemented with additional quantity of potentially limiting amino acids, lysine and methionine. The amount of corn oil in all the rations was adjusted to maintain metabolizable energy contents at 3000 and 3200 Kcal/Kg for the chick starter and grower rations, respectively. The amino acid contents of starter and grower diets were kept higher than NRC (1994) standards. On day 22nd, the birds were transferred to growing cages maintained at room temperature and similarly fed grower diets ad libitum until 42 days of age. The data on feed intake, body weight gain were collected. Feed conversion efficiency were calculated. On day 42nd of the experiment, the experimental birds were fasted for 3 hours and blood samples were collected from the wing vein from randomly selected, 2 birds each of both the sexes per replicate for determination of blood biochemical composition following standard laboratory procedures. Gross pathology of tissues obtained from slaughtered birds was also performed. The study was conducted according to Randomized Complete Block. Design (RCBD). The data thus recorded was subjected to statistical analysis using Analysis of Variance Technique (Steel et al., 1997). The means were compared using Duncan's Multiple Range (DMR) Test (Duncan, 1955).
The results of this study showed significant (p?0.01) difference in average feed intake among treatments and between sexes of broilers. In male broilers, the significantly highest feed intake was observed in birds fed diet C followed by those fed diets D, A and B, whereas in female broilers the highest feed intake was recorded by the birds fed diet A and then followed by those fed diets B, C and D. The results further showed non-significant differences in feed intake of male broilers between treatment groups C & A and C & D, whereas significant difference was recorded between group B and C. Significantly lowest feed intake was recorded in female broilers fed diet D which was also significantly different from treatment groups A and B. The results also showed that with increase in inclusion levels of algae in female broilers depression in feed intake increased. The results in respect of average weight gain showed that male and female broilers fed the control diet attained the highest weight gain, followed by those fed diets C, D and B, respectively in male broilers and fed diets C, B and D in female broilers, respectively. The male broilers attained significantly (p<0.01) better weight gain than female broilers. The weight gain in broilers fed the control diet was not significantly (p?0.05) different from those fed diet C. The overall results of the study showed depression in weight gain of birds fed diets containing different levels of algae in comparison to those fed control diet.
In the present study, the feed conversion ratio was significantly (p< 0.05) influenced by the diets, however it was not significantly different between sexes. In male broilers the poorest FCR was observed in group D followed by in groups B, C and A. The best FCR in male broilers was recorded in group A which was significantly better than that of treatment groups A and D, however non- significant difference between FCR of groups A and C was recorded. In female broilers, the best FCR was observed in birds fed diet C followed by those fed diets A, D and B, however, non- significant difference in FCR among diets was recorded.
Non- significant (P > 0.05) differences in plasma alkaline phosphatase (AKP), alanine transferase (ALT), serum cholesterol, tri glycerides (TG) and non-esterified fatty acids (NEFA) levels among diets and between sexes were detected. Significant (P > 0.05) differences in serum uric acid among diets and between sexes were detected. Female broilers had significantly higher uric acid levels than male broilers. In male broilers fed diet A, plasma uric acid value was observed to be significantly higher than those fed diet D but it was not significantly (P>0.05) different from those fed diets B and C. In female broilers fed diet A, plasma uric acid concentration was significantly higher than those fed diets C and D, however the differences were observed to be non-significant. Significant (P?0.05) difference was observed between uric acid values both in male and female broilers fed diets B and D, however, female broilers fed diet C differed non- significantly (P?0.05) from those fed diet D. On overall basis, there was significant (P?0.05) reduction in uric acid concentration by addition of 7.5 percent algae in the diets. No gross pathological lesions were seen on internal and outer surfaces of gizzard and proventriculus and these were normal in size, however, the internal membrane of gizzard was darker yellow color in birds fed diets containing algae. No lesions were noticed on liver, spleen and intestines and liver and spleen were normal in size. Liver was also of normal color.

Publisher: 2013Dissertation note: Poultry feed industry worldwide has been using antibiotics for more than 50 years. But the use of antibiotics as growth promoters was completely banned in 1999 by the European Union (EU) (European Commission, 2001). This was due to increases in microbial resistance to antibiotics and residues in chicken meat products which might be harmful to consumers.
In Pakistan poultry feed industry is using antibiotics. But internationally their alternatives mannan oligosaccharides (MOSs) are being used. MOSs, which are derived from the cell wall of Saccharomyces cerevisiae, have shown promising effects, such as decreasing pathogenic microflora of the gut, stimulating a strong immune response, and elevating the strength of the intestinal mucosa in poultry. Exact mechanisms by which MOSs show positive effects are not known but some suggestions are they provide nutrients, they aid in digestion of foods and inhibit harmful bacteria in the gut (Owings et al.1990). Gastrointestinal normal flora plays an important role in the health and performance of poultry (Thong song et al.2008). It is therefore of vital importance, both from an animal and human health perspective, to obtain natural alternatives like mannan oligosaccharide (MOSs).
MOSs have been shown to increase growth in broilers (Yusrizalet al. 2003), turkeys (Kannanet al.2005), and results of many trials indicated that MOSs can be one of the best alternatives to antibiotic growth promoters (Hoogeet al.2003), and even trace amounts of MOSs added to a ration were quite effective in increasing the health status and production of poultry (Savage et al. 1997). Stanczuk et al., reported that supplementation of rations with MOSs and inulin (0.1% and 0.4% MOS in diet) did not significantly affect live body weight (BW), feed intake (FI), or feed conversion efficiency (FCE) in turkeys in an 8-week trial (Stanczuket al., 2005).
Actigen a product by Alltech, Inc., is having advanced form of mannan oligosaccharide, which was offered in feed to broiler birds in this trial. It acted as alternative to antibiotics without affecting the performance of birds, It protected the birds from pathogens. Keeping in view the situations the present project was planned. In this studymannan oligosaccharide (MOS) was evaluated on broiler (5*6*15=450) as antibacterial and growth promoter alone or in combination with antibiotic (neomycin) in environmentally control shed of Poultry Research and Training Centre, Department of Poultry Production, UVAS-Ravi Campus, Pattoki. Duration of this trial was 35days.The parameters of this experiment were feed intake, body weight gain, feed conversion efficiency, mortality, carcass characteristics, and slaughter parameters, estimation of ALT, AST and cholesterol from blood. Statistically data was analyzed by using ANOVA in completely randomized design (CRD) with help of a special computer based statistical package (SAS9.1, 2002-03).The results showed that there was significant difference in feed intake when birds were fed with 0.1% MOS with antibiotic from other dietary treatments. MOSs and antibiotics alone or in combination depicted significant results upon weight gain. They were significantly different from control. There was significant decrease in FCE in groups where MOSs was used in combination with antibiotic and more in 'A' 'B' and 'D' respectively. There was significant decrease numerically regarding mortality but statistically there difference was non-significant. Effect of dietary treatments on relative organs weight was non-significant. There was also a non-significant effect on dressing %age. Regarding sera ALT level there was significant decrease in treatment groups than control group. Value of AST level was also significantly less in treatment groups than control group. There was not a significant difference in serum values of triglyceride. Cholesterol level decreased in treatment groups 'B' and 'C' significantly than control but increased significantly in groups 'D' and 'E' than control group. The outcome of this study is that MOS have definite effect on bird's performance and could be used in combination or as an alternative to antibiotics. It is cost effective and beneficial for human health and poultry industry of Pakistan.

Publisher: 2012Dissertation note: These experiments were conducted to study the effects of Azadirachta indica admixed in poultry feed on weight gain performance, haemtological values,immune modulations, and toxic effects in broiler chickens. A total number of 144 commercial broiler 1-day old chicks were reared in the experimental sheds of the Department of Pathology, University of Veterinary & Animal Sciences, Lahore, The birds were fed with balanced commercial feed and water ad libitum. The birds were divided into 3 groups; A, B and C having fourty eight chicks each. Birds of all groups were sub divided into four groups of each i.e. A1, A2, A3 and A4; B1, B2, B3 & B4 and C1, C2, C3 and C4, respectively. Each of the sub groups containd 12 birds. Sub groups A4, B4 and C4 were control group with no medication. The birds of groups A, B and C were fed with poultry feed containing dry powder of neem leaves @ 2 gm, 4 gm and 6gm per kg of feed respectively. The birds of groups A1, B1 and C1 were treated with the herb from day 0 to 42 of their life. The birds of groups A2, B2 and C2 were given the neem from day 14 to 42 of their life, whereas the birds of groups A3, B3 and C3 were treated with the herb from day 28 to 42 of their life. Difference between weekly weight gain in the birds of groups A1, B1 and C1 was non significant (P>0.05) however the difference between weight gain in the treated and control groups was significant (P<0.05). The birds treated with the herb from day 0 of their life showed more weight gain. There was no difference in the haematological indices between all of the treated groups and the control groups. The neem treated birds showed increased antibody titers against ND and IBD viruses as compared to control groups. The values of ALP and ASTshowed decreasing trend when the level of neem leaf meal was increased in the ration. Serum creatinine and serum uric acid values posed a slight declining trend in the neem fed birds. There was a decrease in serum cholesterol level in the neem treated bird groups, the higher the concentreation of the herb, the lower the cholesterol value. The organ body weight indices showed that there was no significant difference in liver, spleen and thymus weights among treated groups as well between treated and control groups. There was absence of prominent gross pathological lesions in liver, spleen, kidneys and thymus, however some treated groups showed mild hypertrophied liver and kidneys as did the organs of the birds in control groups. No histopathological changes except a few mild changes were observed in liver, spleen, kidneys and thymus in the birds of experimental groups.

6 mice in this group were treated with SN at 20 mg/kg intraperitoneally (i.p) and any effects on righting reflex recovery time were noted.
Sodium Thiosulphate (ST) alone (Group 27)
A group of 6 mice in group 27 were treated with ST at 600 mg/kg intraperitoneally (i.p) and any effects on righting reflex recovery time were noted.
Aqueous Garlic Extract (AGE) + Sodium Nitrite (SN) (Group 28)
The mice in group 28 were treated with AGE + SN at 750 mg/kg and 20 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was noted.
Aqueous Garlic Extract (AGE) + Sodium Thiosulphate (ST) (Group 29)
A group of 6 mice in this group were treated with AGE at 750 mg/kg and ST at 600 mg/kg intraperitoneally (i.p) and righting reflex recovery time was recorded.
Sodium Nitrite (SN) + Sodium Thiosulphate (ST) (Group 30)
A group of 6 mice in group 30 were treated with SN and ST at 20 mg/kg and 600 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was recorded.
The efficacy of the antidote estimated was based upon the reduction in righting reflex recovery time.
The righting reflex recovery time that was close to 1 hour was determined against KCN regimen. AGE was tested as potential antidote against sub-lethal KCN toxicity at dose regimens 250, 500 and 750 mg/kg intraperitoneally as well as orally at dose regimens 250, 500 and 750 mg/kg 5 minutes before and 5 minutes after KCN administration. SN and ST were tested at 20, and 600 mg/kg respectively as antidotes against sub-lethal KCN toxicity, 5 minutes before and 5 minutes after KCN administration. These were also tested in comparison and a dose with minimum recovery time was noted. A comparison was made between the efficacy of AGE and SN or ST or SN + ST as potential antidote against sub-lethal KCN toxicity. After 48 hours 3 mice from each group was sacrificed for postmortem examination.
For this purpose the righting reflex recovery time and survival data was collected for each mouse challenged with KCN. A group of 3 mice was tested with each increasing dose of KCN to create dose response curves for both righting reflex recovery times and percent survival. Increasing doses of KCN increased the recovery time of the righting reflex. The dose 5.5 mg/kg of KCN showed the righting reflex recocery time mean 64.66 ± .333 min and was selected for trials.
AGE (750 mg/kg) showed the most significant results as compared to ST and SN alone as well as in combination. Second most effective drug was ST as it showed better results than SN. Treatment results were more pronounced in 5 min pre-KCN groups as compared to 5 min post-KCN groups.
From this study it was concluded that the aqueous AGE is an effective antidote against sub-lethal KCN toxicity as the recovery times indicated that its effects are more pronounced than SN and ST, secondly, as it is easily available and very much cheaper in Pakistan and due to easy unavailability of SN and ST, it is effective antidote that could be used in the field against sub-lethal KCN toxicity with comparatively better results both orally and intraperitoneally.

Publisher: 2013Dissertation note: Lactose is milk sugar. It is found in milk and dairy products. Lactase (Betagalactosidase lactase-phlorizin hydrolase) is the enzyme present in the enterocytes of small intestinal brush border and it is responsible for the breakdown of lactose into its monosaccharide components glucose and galactose that are absorbed into the bloodstream. Lactasedeficiency leads to lactose mal-absorption and resulting gastrointestinal symptoms of intolerance.Lactose intolerance is defined by symptoms of mal-absorption such as abdominal pain,bloating, distention, flatulence and diarrhea due to partial digestion of lactose. This study was conducted in following phases. Lactose intolerance test was performed to diagnose lactose intolerance. In 1st phase lactose solution was prepared by dissolving 25grams of synthetic lactose in 250ml water and in this way 10% lactose solution was prepared and fasting blood glucose level of students was recorded first by using Glucometer. During 2nd phase lactose solution was given to each student and time was noted.During 3rd phase after giving lactose dose blood glucose level of each student was recorded at 30, 60 minutes.
Test was consider positive ifafter lactose solution dose the rise in fasting blood glucose level was less than 20mg per deciliter and if rise in fasting blood glucose level was more than 30mg per dl within 1 hour of lactose solution consumption, test was considered negative. If rise in blood glucose level was between 20 and 30mg/dl then on the basis of sign and symptoms of intolerance, it was decided either a person was lactose intolerant or not. According to the criteria mentioned above significant outcomes of the present research are summarized as following:
Out of 300(100.0) %, 213(71.0) % had positive lactose intolerance test and 87(29.0) % had negative lactose intolerance test.This study determined that prevalence of lactose intolerance in the UVAS, Lahore students was 71.0%. Correlation of lactose intolerance with gender, age, height, BMI, dietary food preferences was determined using chi square test and Phi Cramer's V, p value was considered significant at p <0.05. Chi square results were significant for age, height and weight. On the basis of finding of this study it can be stated that prevalence of lactose intolerance increases with increase in age, increase in weight and height.Chi square results were insignificant for gender, BMI and dietary food preferences, so prevalence of lactose intolerance is independent entity for gender, BMI and dietary food preferences.
Chi square test of independence was calculated comparing the frequency of lactose intolerance for dietary food preferences of subjects. No-significant relationship was found, X2 (2) =3.696, p = 0.158, so p >0.05. There was no correlation between the dietary food preferences of subjects and the lactose intolerance. Phi Cramer's V was used to determine strength of association between lactose intolerance anddietary food preferences of subjects.No significant relationship was found between frequencies of lactose intolerance dietary food preferences.Phi=0-.111, Cramer's V=0.111,p >0.05
There was no difference in results of the dietary food preferences of subjects and the prevalence of lactose intolerance and we can conclude that people who consumed milk products compared to those who did not consume milk/ milk products were equally affected by lactose intolerance as the non-milk product consumers and use of lactose containing milk products does not affect the prevalence of genetically inhered hypolactasia and this is in accordance with Troelsen (2005) findings, Enattah et al. (2002) findings on adult-type hypolactasia and also in accordance with Lisker et al. (1975) and Sahi et al. (1973) findings on recessive inheritance of adult type of intestinal lactase deficiency and recessive inheritance of adult-type lactose malabsorption respectively.

Publisher: 2013Dissertation note: The present study was managed to investigate the possible causes of selective Lernaea attack in different fish species. Planned studies were conducted in five trials. During the first trial lernaea susceptibility and infestation were observed in indigenous major and exotic Chinese carps. Studies were conducted in 4 earthen ponds with two ponds per experimental group. Fishes in the both groups were fed isonitrogenous diet containing 40% crude protein formulated with different feed ingredients. Fishes were identified and examined for the presence of Lernaea species. The parasites were removed and preserved in vials containing 5% formalin. Other growth parameters i.e. average weight gain, average increase in length while physico-chemical analysis including dissolved oxygen, pH, electrical conductivity, water temperature, salinity and total dissolved solids, Chlorides, Phosphates ions (PO4-2), nitrates (NO3) and secchi disk visibility were recorded. The fishes were treated with Tender, an organophasphate (DDVP (Dichlorvos) or 2, 2-dichlorovinyl dimethyl phosphate) for the control of lernaea.
The results showed that C. catla is the most susceptible fish to L. cyprinacea infestation and its appropriate control for conservation of this precious and declining fish is of extreme importance. Thunder is biologically safe as it is biodegradable and degenerated after 36 h without causing any negative effect on the water quality parameters and other water flora and fauna. Treatment of L. cyprinace with 'Thunder' (0.10-0.25ppm) gives promising results without adverse effect on fish life. Though DDVP worked well in its control but its heavy infestation really weaken fish incapacitating its feeding and competing abilities with its counterparts.
In the 2nd trial, comparison of bio-chemical profile was observed on healthy and infected Indian and Chinese major carps. The experiment was managed in four earthen rearing ponds (59m x 30.5m x 1.8m). There were two-groups, one group without any treatment served as control and the second as treatment. At the outset of trial all the fish species were weighed, measured and comprehensively examined for presence of L. cyprinacea and general health condition. Fishes from both groups were dealt uniformly except administration of regular applications of DDVP (0.25ppm in treatment group while no any medication in control group. Water quality parameters DO, pH, electrical conductivity, water temperature, salinity and total dissolved solids, chloride ion (Cl-1), phosphate ions (PO4-2) nitrates (NO-3) and light penetration were recorded. Samples of healthy and infected fishes of each species were collected for proximate composition (moisture, ash, crude protein, crude fat) and minerals (Iron, Zinc, Calcium, Copper and Magnesium) and phosphorous analysis.
The results showed that dry matter, fat and crude protein percentages were significantly decreased in lernaeid fishes. Moisture and ash contents of fishes increased in infected fishes as compared to healthy and treated fish. A slightly lower level of protein (12.65±0.49) and fat (7.30±0.28) in C. catla was observed than rest of the species. The protein was the highest (26.00±4.24) in L. rohita while the fats were the highest (10.55±0.92) in C. mrigala and C. carpio the second highest. Similarly looking at mineral profile there is not much difference, so it is hard to say that level and type of nutrients are solely responsible for L. cyprinacea attack. Mineral composition of infected fish indicated that minerals balance upsets during disease condition. Pathogenicity is a complex of so many factors, which encompass environmental, biological, and physiological so still lot remains to be explored before issuance of any concrete conclusion and recommendation that which factor is more active and critical in inviting and attracting this parasite.
In the third experiment, various blood indices were compared among Chinese and Indian major carps from the perspectives of their resistance against lernaeaosis that included probable role of blood and its components in reception of L. cyprinacea in some commercially important locally culturable herbivorous fish varieties while repulsion in others living under similar environment.
Healthy samples of each fish species were selected and blood was immediately drawn by puncturing gill lamellae, caudal vein and heart of both male and female of each representative experimental species. Blood parameters including Red Blood Cells (RBC, 10 -6/µL), White Blood Cells (WBC, 10-3/µL) and Platelets (10-3/µL) in blood from experimental fish species were counted by placing sample on haemocytometer grids. Differential Leucocyte Count (DLC), red blood indices, blood chemistry and ESR were determined for males and females of experimental fishes.
The results revealed that females of each species have relatively higher values for blood indices as compared to males. C. carpio has maximum number of granulocytes that may support the fish against the parasitic attack. C. catla has the lowest values for the immunoglobulin Ig M as compared to the species which showed less susceptibility.
In the 4th trial, healthy fishes of major and Chinese carps were collected from commercial rearing and grow out ponds. Each fish weighed 830 ± 316 g on the average. For mucus collection, fishes were bathed in Potassium permanganate (KMnO4) solution (8.0 ppm) to remove microbial or fungal infection/infestation. Samples were centrifuged at 12000×g at 4 ?C for 10 minutes and stored at -40?C in biomedical freezer. Bradford Micro Assay technique was applied to determine protein contents. Bradford protein solution (50 ?L) was added to each well and absorbance was recorded at 595nm. Standard curve was drawn from various but consecutive dilutions of BSA solution and protein concentrations in different samples were calculated. Electrophoresis was carried out with slight modifications. 15% separating and 4% staking buffer were used to run the SDS- PAGE under constant voltage of 120. Fermentas PageRuler™ protein ladder was used as the standard marker for non reducing protein. The gel was stained with PageBlue™ (Fermentas) stain for identification of protein bands for molecular weight determination. Lectin activity and Alkaline Phosphatase test were determined. Mucus was incubated with 4 mM p-nitrophenyl phosphate in ammonium bicarbonate buffer (100 mM) with 1 mM MgC12 (pH 7.8) at 30°C. The increase in optical density (OD) was measured continuously for 2 to 3 hours at 405 nm using a micro plate reader.
The results showed that lectin activity was the highest in C. idellus (109) indicative of low resistance while it was the lowest (21) in H.molitrix which was completely parasite free. Alkaline phosphatase level was the highest in C. catla, C.idella was the second highest and was the lowest in C. carpio. Protein concentrations were the highest in C. idella (3.29 ± 0.13 mg/ml) and C. catla (3.02 ± 0.57 mg/ml) while it was the lowest in C. carpio (1.80 ± 0.09). C. catla contained the highest molecular weight proteins (100 kDa) while C. carpio has one unique protein band of 14.13 kDa not present in any other species in current setup.
In the 5th experiment, the lernaea were observed in the month of June to August. Lernaeied infestation was observed in all experimental fishes except in C. carpio. After appearance of infestation fishes were treated with Thunder (DDVP- an organophasphate) to eliminate the parasite. Parasite free C. idellus, H. molitrix, L. rohita, C. mrigala, C. catla and C. carpio were collected with an average weight of 830 ± 316 g each were used for studies on whole-body amino acid composition. Triplicate samples of each species were over dried after evacuating their gut contents. Dried samples were then finely powdered, sieved and vacuum hydrolyzed in 2 ml of 6 N HCl at 1lO°C for 24 hours. Total amino acid composition was determined by o-phthaldialdehyde (OPA) method using an Agilent chromatograph, revers-phase high performance liquid chromatography (HPLC). The results showed that the essential amino acids (arginine, lysine, phenylalanine, tyrosine, histidine and leucine) play a major role in the immune system. It is revealed that amino acids will widely become cost-effective neutraceuticals for improving health and preventing infectious disease in animals. C. carpio have no infestation due to increased numbers and concentrations of essential amino acids when compared to other species of Indian and Chinese major carps. C. catla, C. idella and H. molitrix have the lowest number and concentration of essential amino acids and hence appeared more susceptible to lernaea attack.
Finally it was concluded from the entire study that C. carpio may have high resistance for the L. cyprinaceaea as compared to the other experimental fishes. It possesses higher values for Ig M-immunoglobulin as compared to C. catla that indicated its high immunity against the parasite. Similarly C. carpio has maximum number of granulocytes (WBCs, esinophils, basophils and lymphocytes) that may support the fish against the parasitic attack. SDS-PAGE analysis of mucus revealed that C. carpio has one unique protein band of 14.13 kDa not present in any other species in current setup. This protein band may indicate the presence of lysozyme enzyme that actively participates against the invading pathogen. Essential and non-essential amino acids concentrations were also higher in the C. carpio that play a vital role in immunity especially arginine, lysine, phenylalanine, tyrosine, histidine, leucine, glutamic acid and aspartic acids.

Publisher: 2013Dissertation note: In spite of the significance of dairy animals to poor citizens relatively is the neglected area of research. Considering this an active surveillance based study was conducted to analyze the impact of climate change on the epidemiology of diseases in dairy animals in Khyber Pakhtunkhwa (KPK) province, Pakistan. Ecologically and geographically two different clusters having four randomly selected districts each; furthermore randomly a single village from each district was selected. Data from 1252 (49.8%) cattle and 1260 (50.2%) buffaloes was collected on a predesigned questionnaire about the epidemiological parameters for the period of one year i.e. from July 2012 to June 2013. The results revealed a significant (p < 0.05) association of change in environmental temperature with the morbidity, mortality and case fatality rate of the diseases and major health problems. As the mean temperature at lower altitudes (below 500m) increases above 300C the rates of incidence of disease also increases. While at higher altitudes temperatures when increases above 300C the rate of incidence increases faster than in HCC. In CCC, the higher morbidity rate was due to ID in cattle and RB in Buffalo population and in HCC RB was higher morbidity causing health problem in both species. While in terms of mortality and case fatality HS was the leading cause in both clusters and species. The results also showed that the susceptibility of buffaloes and cattle to heat stress varied significantly according to specie, breeds, genetic potential and life stage. It was concluded that climate change do have an impact on occurrence, pattern and severity of health problems and infectious diseases at different altitudes. Further research work is needed to find out the best breeds in terms of production and reproduction that could well establish themselves in these climates.

Publisher: 2013Dissertation note: Catheter-associated urinary tract infections (CAUTIs) are most common type of nosocomial infection. This study was designed to recognize and identify the bacterial pathogen of catheter-associated urinary tract infection in patients, the sensitivity pattern of bacterial pathogens to commonly used antibiotics and the synergistic effect of antibiotics with ascorbic acid to improve the efficacy of antibiotics. The prospective, observational study was conducted in Sir Ganga Raam hospital Lahore. The urine samples from 100 catheterized patients were collected and were analyzed for its causative /pathogenic organism. Out of 100 patients, 58 patients carried E.coli (27%), Citrobacter (22%), Enterobacter (5%) and Staphylococcus aureus (4%) and these patients were included in study. Sensitivity patterns of Ampicillin, Co-amoxiclav, Ceftriaxone and Ciprofloxacin were checked by Kirby-Bauer disk diffusion method. Uropathogens appeared to be highly resistant against Ceftriaxone (84%), followed by Co-amoxiclave (83%) and Ampicillin (76%).Amikacin and Ciprofloxacin are effective drugs against uropathogens and their sensitivities to Amikacin and Ciprofloxacin were 74% and 71% respectively.
Susceptibility testing of bacteria against antibiotics and ascorbic acid alone and in combination was checked and it was observed that bacterial resistance to Ceftriaxone was reversed with ascorbic acid and the effectiveness of ciprofloxacin was improved with ascorbic acid. In Citrobacter, ascorbic acid antagonized the effects of Amikacin.
Empirical therapy of patients included in study was evaluated by clinical response and their definitive therapy was assessed by observing the adverse effects associated with that drug. Co-amoxiclav produced 100% side effects. Tinnitus (63%) was observed in patients treated with Amikacin while Ciprofloxacin adverse effects were headache and dizziness.
It was concluded in the study that there was high incidence of infection in catheterized patients with resistant bacteria and inappropriate antibiotic therapy. Ascorbic acid may be prescribed prophylactically to catheterized patients and to those who take Ceftriaxone to minimize its resistance in patients. To improve the effectiveness of drugs in CAUTI patients, ascorbic acid may be used with antibiotics.

Publisher: 2013Dissertation note: Vehicular air pollution is a mounting health issue of the modern age, particularly in urban populations of the developing nations. Auto rickshaws are not considered eco-friendly as to their inefficient engines producing large amount of particulate matter (PM), which poses a significant environmental threat.
Major transformations in the environmental composition are principally attributable to the combustion of fuels by automobiles. Motorized gasoline powered two-stroke auto-rickshaws (TSA) and CNG powered four-stroke auto-rickshaws (FSA)are major sources of air pollution in south Asia and produce toxic amount of PM to the environment. In this study, during the first phase, the PM of TSA and FSA was characterized by using proton induced x-ray emission (PIXE) analysis. The observations of the existing investigation recognized significant increase in Al (P < 0.05), P (P < 0.01), and Zn (P < 0.01) from the PM samples of FSA. In addition, the concentrations of Cu, Fe, K, Mn, Mg, Na, S and Si were also observed exceeding the recommended NIES limits. On the contrary, increased concentration of Sr and V were observed in the PM samples from TSA. It is generally believed that FSA generates smaller amount of PM but the data obtained from this study clearly shows that emissions from FSA are comprised of potentially more toxic substances than TSA. The current research is specific to the metropolitan population and has evidently revealed an inconsistent burden of exposure to air pollutants engendered by FSA in urban communities, which could lead to disruption of several biological activities and may cause severe damage to entire ecological system.
The second phase of this study was conducted to ascertain toxic effects on angiogenesis, embryo development, embryonic movement and phytotoxicity of the PM from TSA and CNG powered FSA. Based on high amounts of aluminum quantified during PIXE analysis of PM from TSA and FSA, different concentrations of aluminum sulfate were also tested to determine its eco-toxicological potential. The PM solution from FSA, TSA and Aluminum sulfate exhibited anti-angiogenic potential with reduction in total area of CAM. Morphological evaluation of embryos exhibited varying degrees of hemorrhages in different groups. In case of phytotoxicity screening using Zea mays, the results demonstrated that all three tested materials were equally phytotoxic at higher concentrations in seed germination(p<0.001). Aluminum sulfate proved to be a highly phytotoxic agent even at the lowest concentration examined.
During the last phase, of the study, the MTT assay demonstrated a significant (p<0.001) dose dependent cytotoxic effect for TSA, FSA and aluminum sulfate on the BHK-21 cell line, establishing that the PM from FSA is a highly cytotoxic material. Mutagenicity was assessed by fluctuation Salmonella reverse mutation assay adopting TA100 and TA98 mutant strains with (+S9) and without (-S9) metabolic activation. Despite the fact that different concentrations of PM from both sources i.e. TSA and FSA were highly mutagenic (p<0.001) even at lower concentrations, the mutagenic index was higher in TSA. The chronic toxicity study revealed that chronic exposure to PM emitted from FSA and TSA resulted in peribrochiolitis, emphesema and infilteration of leukocytes in lung tissues. On the other hand liver, cardiac and kidney tissues exhibited degeneration and necrosis. The data shows that all tested materials are equally ecotoxicand if the existing trend of atmospheric pollution by auto-rickshaws is continued, air-borne metals/heavy metals will seriously affect the normal growth of local inhabitants and increased contamination of agricultural products, which will amplify the dietary intake of toxic element and could result in genetic mutation or long-term health implications.

Publisher: 2013Dissertation note: Metformin most commonly prescribed oral anti hyperglycemic drug for type 2 diabetes whereas Sitagliptin recently approved oral antidabetic drug for type 2 diabetes were evaluated for their mutagenic and genotoxic potential alone and in combination with three artificial sweeteners (Saccharin, Aspartame and Acesulfame-K) normally consumed by diabetic individuals.
In this research project Ames Salmonella/microsome assay was performed to check the mutagenicity of Metformin and Sitagliptin alone and in combination with artificial sweeteners using mutant Salmonella tester strains TA100 and TA98 with and without the S9 whereas Genotoxicity was evaluated by Single Cell Gel Alkaline Electrophoresis/Comet.
The results indicated that Metformin alone showed mutagenic effect at 120µg/plate against TA100 with S9mix. However Metformin when tested in combination with artificial sweeteners, significant enhance in mutagenicity occurred only against TA100 with and without S9. Sitagliptin displayed mutagenic potential only to TA98 with S9mix at the concentration of 3040µg/plate. In addition significant enhance in mutagenicity occurred when tested in combination with artificial sweeteners against both strains with and without S9. In case of genotoxicity both Metformin and Sitagliptin results indicated significant increase in DNA damage in dose dependant manner as compared to negative control. Though Metformin and Sitagliptin in combination with artificial sweetener did not reveal any significant boost in the genotoxicity relative to when they were tested alone.

Publisher: 2014Dissertation note: Background:
This project was designed to evaluate the anthelmintic efficacy of Chloroformic extract of Calotropis procera leaves against sheep nematodes. For this purpose hundred sheep positive for nematodal infection in BLPRI Kherimurat were selected after fecal examination.
Methodology:
The hundred animals were divided into 5 groups (Group A, Group B, Group C, Group D and Group E) having 20 animals in each group. Fecal eggs counts (EPG) and biochemical tests like the Alanine aminotransferase (ALT), Aspapartate aminotransferase (AST), Alkaline phosphatase (ALP), Albumin, Bilirubin, Creatinine and Urea were done on the day zero of the treatment. For further study, Group A served as an un-treated control. Group B, Group C and Group D were given the Chloroformic extract of Calotropis procera leaves at the dose rate of 3, 6 and 12mg/kg body weight by oral route respectively. Group E was given the Moxidectin at the dose rate of 0.2mg/kg body weight by subcut route. The biochemical tests on the day 3 showed no change in the normal level of the ALT, AST, ALP, Albumin, Bilirubin, Creatinine and Urea.

Publisher: 2013Dissertation note: Short term Preservation of broiler breeder semen is an unnatural method in which spermatozoa faces oxidative stress, osmotic and thermal shocks. This affects preserved semen quality resulting in low conception rates. In order to overcome oxidative stress, Butylated Hydroxytoluene was used as antioxidant in poultry semen during short term preservation at 4ºC for 48 hours.
Keeping in view the significance of BHT as a potent antioxidant, the present study was conducted to determine the significance of BHT inclusion in preserved Hubbard broiler breeder semen for reduction of oxidative stress. In the current study, semen from six (n=6) healthy broiler breeder was collected by abdominal massage and butylated hydroxytoluene (BHT) was added to the semen @ 0.5, 1.0, 1.5 and 2.0 mM. One group was kept control and no BHT was added to that group. The routine quality evaluation of semen for motility and concentration was made, extender was added and then semen was stored at 4°C for 48 hours.
The parameters evaluated were percentage motility, plasma membrane integrity (HOST), viability (Live/Dead) and DNA integrity (Acridine orange assay). Seven samples were taken from each concentration of BHT and thawed individually in water bath at 37°C for 30 seconds and evaluated for quality parameters. In conclusion, the addition of 1 mM BHT to semen extender improved marginally the broiler breeder spermatozoa motility, viability, plasma membrane integroty and DNA integrirty at different period of time.
In controled group the quality of semen after preservation was poor due to oxidative stress which will effect the fertility rate. The Butylated Hydroxytoluene has antioxidant properties, so inclusion of BHT in preserved Hubbard broiler breeder semen was tested in our research.

Publisher: 2013Dissertation note: Livestock plays pivotal role in the economy of country and small ruminants are the major source of food products for human. Haemonchus contortus is the most significant parasite of small ruminants and cause heavy production losses by causing reduction in meat and wool production. The parasite directly affects the health of an animal and causes anemia, hemorrhages, anorexia, weight loss and death of affected animal.
This study was designed to diagnose the Haemonchosis in sheep in and around Lahore. The accurate diagnoses of the parasite are important for its control and treatment. Direct smear, floatation technique and Polymerase Chain Reaction (PCR) were applied to check the sensitivity and specificity in diagnosing Haemonchosis in sheep. For this purpose 100 faecal samples were collected randomly from different areas of Lahore. Each faecal sample was examined by direct smear method and floatation technique. Out of 100 faecal samples 44 were microscopically positive. 30 by direct smear method and 44 by floatation technique.
Specific primers were designed to diagnose Haemonchosis in sheep by using ITS-2 Region. 44 microscopically positive samples were confirmed by PCR. 29 (66%) samples were found to be PCR-positive and 15 (34%) were found to be PCR-negative.
Several other species of parasites were also found during microscopic examination of faecal samples. Two samples wetre found positive for coccidial oocyst and seven samples were also positive for other nematodes along with Haemonchus spp.
Flotation technique was found to be superior in diagnosis of Haemonchosis as compared to direct smear.
Conclusion:
From current study it is concluded that Haemonchosis is widely prevalent in ovines. Its accurate diagnosis is essential for the treatment of infectious diseases and control of this parasite. Molecular technique has the advantage over conventional diagnostic techniques because PCR is more specific than conventional methods of diagnosis. According to the present study by conventional method there is 34% error chances to diagnose other Trichstrongylid eggs as Haemochus spp. The main advantage of using PCR as diagnostic test, are an increased speed of diagnosting the disease and its capability to notice low worm burden in small volume of faeces from individual animals.

Publisher: 2013Dissertation note: Three kiddings in two years or five kiddings in three years refers as accelerated kidding which is helpful to have more kids, helps to fetch higher market prices during off-season. This can also increase life time production in the form of meat, milk and fiber. High reproduction rate is the basiccondition to increase efficiency of production. Most of the goats do not follow seasonal breeding pattern and breed round the year resulting in management problems and high mortality during severe weather conditions. Accelerated kidding strategy is a viable option that affects the health and fertility of the flock. In the present investigation, three experiments were conducted at Small Ruminant Training and Research Centre (SRT&RC) Ravi Campus Pattoki, UVAS, Lahore. The experiment-I was about the initiation of estrus activity in anestrus Beetal goats during low breeding season. Twenty Beetal goats were selected from the existing flock, maintained at SRT&RC. These goats were divided randomly into 4 groups i.e. A, B, C and D having 5 animals in each group. Group A was treated as negative control by offering only green fodder, group B was provided flushing ration along with green fodder (control), group C was kept on green fodder along with hormone therapy of gonadotropin releasing hormone (GnRH) and prostagladin (PGF2?) while group D was provided with green fodder, flushing ration (600 gms/animal) and hormone therapy by providing GnRH and PGF2?. Hundred percent estrus induction was achieved in group B, C and D as compared to group A. The results revealed that fertility rate and kidding rate was high i.e. 80 and 60 percent among animals of B group while animals of control group had less fertility, kidding and gestation rate. The shortest gestation length was found in group B and C while triplet births were observed in goats of group D.
The experiment-II was regarding the initiation of estrus through buck effect in Beetal goats. This experiment was conducted in two phases. Phase 1 comprised two groups A and B for which estrus induction was done during pre-breeding (August) and normal breeding (September/October) season. Similarly, Phase 2 comprised two groups C and D in which estrus induction was done during post-breeding (December) and normal breeding (September/October) season. Different reproductive parameters like estrus, fertility percentage, were noted. The data regarding average birth weight (kg) and gestation length (days) were recorded. Estrus signs were maximum in group B while low in group C. However fertility rate was high in group A, instead of group B. Overall kidding percentage was higher in A group but the lowest in group D. The highest gestation length was observed in group D whereas the lowest value was found in group B. Average litter size was higher in group D as compared to A and B group, respectively.
The experiment-III was conducted to compare productive and reproductive performance of Beetal goats in accelerated and annual kidding systems. Total of 50 adult Beetal goats were divided into two groups viz. accelerated kidding and annual kidding having 25 animals each. The does were selected on the basis of their age, body size, weight and parity. Different breeding bucks were used for each group having similar size, weight and age. All the animals included in this study were fed according to national research council (NRC) nutrient requirements for goats (NRC, 1981). Flushing rations and estrus inducing hormones both were provided to the does of respective groups for preparation of breeding activity during out of season breeding. The annual kidding group was considered as the control group, while the does were bred every eight months for accelerated kidding. The offsprings produced by the pregnant does of 1st batch of both the groups were reared under similar managemental conditions up to maturity. Three crops were produced in accelerated kidding system as compared to two crops in annual kidding system. It was observed that more number of animals i.e. 17 out of 25 showed estrus signs as compared to annual kidding system where 15 animals showed estrus signs. There were non significant differences for number of services per conceptionin two crops under annual kidding groups. Higher percentage of estrus was observed in accelerated to annual kidding. Total number of kids produced in accelerated kidding system was 42 with an average 14 kids in three crops while 23 kids were produced in annual kidding system in two years. Average cost of concentrate was observed high in accelerated kidding system as compared to annual kidding system. Birth weight of kids produced in 3 different seasons i.e. March-April, October- November and June-July were found as 2.84, 2.91 and 2.98 kg. The overall results in term of reproductive efficiency, oestrus behavior and kidding percentage were better in accelerated group than annual kidding.

Publisher: 2014Dissertation note: Small ruminants are one of the domestic animals of the inhabitants of Pakistan. In semi-arid and arid areas goat and sheep provides the main means of survival and security. So the proper health management of animals is must require for their survival. Hematlogical and biochemical tests are widely used for the diagnosis of serious animal diseases which can lead to economics losses in animals like reduced fur, wool and milk production. A large number of factors such as sex, age, gender, breed, illness, stress, seasonal variation and nutrition can affect the pattern of these clinical values. Our hypothesis was to evaluate the effect of age and gender on hematological and biochemical indices of Beetal goat and Lohi sheep in Ravi campus Pattoki UVAS.
One hundred and twenty blood samples (60 Goats and 60 sheep) were taken and divided on the basis of their age and gender (0-3 months, 9-12months and 18-20 months). Complete blood counts were performed by hematology analyzer (Abacus junior vet. Serial # 130076, Diatron GmbH wein, Austria) at W.T.O, UVAS. The biochemical parameter included albumin, globulin, cholesterol, triglycerides, total protein, urea AST and ALT were determined by commercially available kits (Biogene® and Crescent®). The arithmetic means (± SE) of hematological and biochemical parameters in different groups were calculated. The arithmetic means (± SE) of hematological and biochemical parameters in different groups were calculated. The collected data were subjected to two way analysis of variance through statistical package SPSS version 13 to evaluate mean differences in hematological and blood biochemical parameters of different age groups. Difference among the means of groups with p<0.05 was considered as significant through LSD test (Steel et al.1997).
In this study age and gender had a remarkable influence on the pattern of hematological and biochemical values of both sheep and goat. The RBCs, Hb, PCV, MCV, MCH, MCHC, WBCs and lymphocytes counts found significantly (p<0.05) higher in animal of age 18 to 20 months as compared to other groups in both species, While MCHC, monocytes and granulocytes found non-significantly (p>0.05) different. Male showed statistically (p<0.05) higher RBCs, Hb, PCV and MCV values as compared to female. The glucose, cholesterol, triglyceride, urea, AST, ALT, Total protein, albumin and globulin were found significantly (p<0.05) different by the aging of animal. Gender had no significant (p>0.05) influences on biochemical parameters of both sheep and goat.
Conclusion
Based on these findings age and gender had significant influence on hematological and biochemical parameters. In general veterinary practices, body weights are usually considered for therapeutic and nutritional strategies. Often too young animals are treated with more caution. In conclusion it can be mentioned that not only body weight but also age of the animals should be considered for devising therapeutic and nutritional strategy in livestock.

Publisher: 2013Dissertation note: Background:
Anthrax is a bacterial zoonotic disease caused by Bacillus anthracis. Accurate assays for etiological identification are necessary to ensure proper veterinary and medical health facilities against such diseases. Real-time PCR is a powerful technique to identify this organism based on the presence of two unique plasmids (pXO1 and pXO2) and is highly preferable technique over conventional detection assays in clinical and environmental samples both.
Methodology:
Real Time-PCR technique was used to identify Bacillus anthracis bacteria in the soils of districts Lahore and Sheikhupura. Soil samples were collected from each village of both districts and processed for genome extraction using commercial soil DNA extraction kit. Following genome extraction, the samples were run further for real-time PCR analysis. Positive controls, primers and probes were provided by the Penn state University. SPSS software and pearson's chi square distribution test were used for statistical analysis.
Findings and Suggestions:
Real-time PCR was found as a powerful tool to detect Bacillus anthracis in environmental samples. The bacterium detected was of non-virulent type and showed associations with soil humidity and land use. Further studies may include study of the bacterium with respect to soil-chemistry and sero-prevalence among positive areas of the two districts. Strain characterization is also recommended. The present results may also help in ecological niche modelling by using spatial mapping techniques. Such studies will help in a better understanding of soil as a reservoir for zoonotic organisms and surveillance of the diseases.

Publisher: 2013Dissertation note: This 9-month study extending from March 1, to November, 30, 2012 was conducted to find out the effect of different feed ingredients on growth, haematology and vital organs in juvenile Labeo rohita. The experiment was performed to find out the cost-effective substitutes of fishmeal and their effect on growth, digestive enzymes activity, blood profile, histology of intestine and flesh quality was monitored. To obtain the said objectives the experimental fish, Labeo rohita was subjected through three different research trials. i. A 3-month research trial was conducted to evaluate the effect of different plant/animal origin feed ingredients on growth, feed conversion ratio (FCR) and survival of fingerling Labeo rohita. Fish was fed on fish meal, guar meal, corn gluten meal (30%), soybean meal, sunflower meal, rice polish, cotton seed meal, canola meal and rape seed meal individually. Statistical analysis revealed significant differences (P?0.05) in growth, average weight gain, average length increase and specific growth rate among various ingredients. The highest average weight gain 27.162±6.950g and average length increase 6.153±0.833cm was observed in fish fed on guar meal while same was lowest 5.327±1.067g and 1.858±0.137cm, respectively in fish fed on corn gluten. However, fish showed better FCR values (2.01±0.08) when fed on guar meal while the FCR was very poor (9.57±48) for corn gluten (30%) fed group. The survival rate was highest (100%) for soybean meal fed group and lowest (70%) in canola and rapeseed meal fed group. ii. During second 3-month feeding trial, the effectiveness of individual feed ingredient from either plant or animal origin on growth, body composition, enzymes activity, haematology, histology and flesh quality of Labeo rohita was observed. The experiment was conducted in ten fiber glass tanks having size 12 ft x 4ft x 3 ft (length x width x depth). Single ingredient was considered as an independent treatment, hence guar meal, soybean meal, cotton seed meal and canola meal were considered as an independent treatment and fishmeal which was considered as a superior ingredient due to its ideal nutrient balance served as control. Ten juvenile Labeo rohita having an average weight of 200±2.33 g were harvested indiscriminately from the bulk and stocked in each fiberglass tank. Two tanks were randomly allotted to each treatment and control. Each group received uniform ration @ 4% of total fish biomass twice a day. Results revealed significant differences (P?0.05) in growth, FCR and specific growth rates among treatments. Weight gain was the highest in guar meal fed fish while the lowest on fish meal. Body composition of fish showed slight variations in fat contents with no differences in other nutrients though chemical composition of individual ingredient varies a lot. Minerals specifically Na, Ca, Fe, Zn, and Cu significantly differed (P?0.05) among treatments which might be linked with their variable release in digestive system of fish in the presence of various anti-nutritional factors. For different feed ingredients protease activity varied significantly (P<0.05) between anterior and posterior part of the intestine and also that of whole intestine when compared among various treatment groups. While amylase activity differed significantly when enzyme activity compared from the homogenate of whole intestine but not when compared partly. WBC, RBC, Hct, HB, PROT, ALB and GLOB showed significant (P<0.05) differences for blood samples of the fish fed with different feed ingredients while values of MCV, MCH, MCHC and ESR remained uniform. The feed ingredients differently affected the liver and intestinal cells. No difference was observed when fried fish fed on different ingredients were compared among each other indicating that ingredients with nominal variations in chemical composition do not leave much after effects on fish flesh. iii. Third 3-month trial was conducted to evaluate the effect of plant-animal feed and/or plant by-product based feed on growth, body composition, enzymes activity, haematology, histology and flesh quality of Labeo rohita. Fish fed on rice polish alone served as control (T0). Previously selected potential fish feed ingredients were grouped together with two ingredients in each isocaloric test diet which served as an independent trial during these studies. Group 1(T1) contained guar meal and canola meal, group 2(T2) soybean meal and cotton seed meal, group 3(T3) guar meal and cotton seed meal, group 4(T4) soybean meal and canola meal and group 5(T5) fishmeal and canola meal. Each group including control had two replicates. 12 earthen ponds with uniform area of 0.03 ha each, were randomly stocked with 100 fish (average weight 200±4.43g) in each following standard stocking protocols. All the 12 ponds were then randomly allotted to individual treatment including control group. Experimental fish were fed @ 4% of their wet biomass twice a day except Sundays which was kept open providing fish an opportunity to clean left over feed from the previous day. Better growth rate, food conversion ratio (FCR) and specific growth rate (SGR) in T3 than rest of the treatments including control suggest that guar meal and cotton seed meal is much better option to include in future feed formulations for maximum performance and minimum feed wastage. This preposition will minimize feed providing cleaner and healthy environment to fish ultimately enhancing stocking rate and fish production. Proximate analysis of dried and ground fish samples showed higher protein values in T4, fat in T2, moisture contents in control, dry matter in T1 and ash in T5. Mineral composition of Labeo rohita showed statistically significant (P ? 0.05) differences in Na, Ca, Fe, Zn and Cu content. Amylase concentration showed non-significant differences in anterior, posterior parts and the whole intestine in all the treatment and control ponds except T5 while protease concentrations were statistically significant (?0.05) in anterior and posterior part within the same group as well as among various groups. Enzymatic activity in whole intestine also varied significantly when compared among groups. Haematological parameters viz. WBC, RBC, ALB, GLOB and PROT differed significantly (?0.05) among all the treatments. Disrupted hepatic cords and hepatocytes showing pyknotic nucleus were observed in T1, moderate infiltration of fat vacuoles in T2 and, T4 caused vacuolar and hepatic cord degeneration while fish from T0 were subjected to severe vacuolation in hepatocytes. Non-significant differences in flavor, juiciness, and oiliness of fried fish from all the treatments and control ponds indicated that the sensory attributes of fish flesh were not affected by feeding fish with blend of various ingredients. It is concluded that the response of body organs varies with varying feed stuffs and the feed items have pronounced effect on enzymatic activities, hematological and histological parameters in juvenile Labeo rohita. During present study fish showed comparatively better growth when fed with guar meal as a single feed ingredient or combined with cotton seed meal than the rest of feed ingredients either offered individually or in combinations. The study provides base line information and will help aquaculture nutritionists to formulate cost-effective feeds.

Publisher: 2013Dissertation note: Iodine has been proved over an extended period of time as antimicrobial especially antiviral and is employed extensively as skin disinfectant. Ascorbic acid also possesses antioxidant and antiviral activities. A micronutrient combination consisting of iodine, ascorbic acid, potassium iodide and excipients have been developed to cope with increasing burden of viral infections in Pakistan and particularly against Hepatitis C Virus clinically. The objective of this project was to analyze antiviral activity, cytotoxic and mutagenic potential of micronutrient combinationthrough H9N1 influenza virus strain antiviral infectivity assay, MTT cell viability assay and Ames Salmonella test, respectively. Commercial preparation of micronutrient combination i.e. MTI Renessans, comparable self-prepared micronutrient UVAS Renessans, pharmaceutical grade individual ingredientsand standard antiviral Ribavirin, Amantadine and Oseltamivir were tested.Renessan's concentrations of 375, 187.5, 93.75, 46.87, 23.43, 11.71, 5.86, 2.93, 1.46, and 0.73ug/ml were employed in these tests while comparable concentrations of UVAS-Renessans and individual micronutrients were analyzed. Ribavirin, Amantadine and Oseltamivir had doubling dilution from 100ug/ml concentrations 14 in descending manner. In MTT assay, confluent monolayer of Chicken Embryo Fibroblasts grown in 96-well cell culture plates were treated with ten concentrations of each extract in triplicate manner and was used to determine the viability of the cells and cell survival percentage was calculated.Antiviral efficacy was determined against influenza virus H9N1 strain by virus infection and subsequent cell viability assay. Cytotoxicity was measured by cell survival analysis after tetrazolium reduction assay (MTT assay) while mutagenicity was measured by bacterial reverse mutation analysis by Amestestusing two strains of Salmonella typhimurium TA100 and TA 98 with and without S9 and after appropriate incubation, number of revertant colonies per plate were counted in triplicate manner and Mutagenic Index MI was calculated. Our combination showed cytotoxicity at doses higher than 93 ug/ml while showed significant antiviral efficacy at concentrations of 93ug/ml, 46ug/ml, 23ug/ml, 11.5 ug/ml, 5.86ug/ml and 2.93ug/mlwhich faded away at lower dilutions. Renessans was found to be non-mutagenic in our experiment. The results are well supported by previous studies and may show a paradigm shift in systemic use of high dose of iodine as antiviral compounds.

Publisher: 2014Dissertation note: Antibiotic resistance is increasing along with the increasing use of antibiotic for the treatment of infectious diseases. The in-vitro study was designed to observe the reversal of
antibiotics resistance in Methicillin-resistant Staphylococcus aureus by non-antimicrobial
agents.
One hundred pus samples were processed for isolation and identification of MRSA.
Out of 100, 37 (37%) islotes were Gram +ve cocci, from these 37 isolates 34 (92%) turn red
colour of mannitol salt media to yellow and 23 (62%) gave +ve catalase and coagulase. In
this study Antibiotic Sensitivity Test was performed on pure culture of MRSA strain by
applying disc diffusion method. Out of 23 pure MRSA isolate, 100% isolates were
methacillin resistant, 79% isolates were co-amoxiclav resistant, 30% isolates were
meropenum resistant, 8% isolates were vancomycin resistant, 26% isoltes were moxifloxacin
resistant and 39% isolates were linezolid resistant. Reversal of antibiotics resistance was
observed by MIC or serial dilution method, using non antibiotic agents like Amiloride,
Lansoprazole and Promethazine, Concentrations of non-antibiotic agents 1024ìg, 512ìg,
256ìg, 128ug, 64ìg and 32ìg were used in combination of antibiotics to reverse the
antibiotics resistance in MRSA. These non antibiotic agents may cause the alteration in
mechanisms by which microorganism develop resistance. The collected data analyzed by
applying analysis of variance (ANOVA) through SPSS 16.0 computer software. Now we would be
able to treat some lethal infection caused by MRSA, and help to increase patient compliance
and decrease the cost of therapy.

Publisher: 2013Dissertation note: The present study was designed to explore the effects of aqueous and ethanolic extract of leaves and seeds of Eugenia jambolana on angiogenesis by means of the chicken chorioallentoic membrane assay. The Eugenia jambolana was collected from the locality of Lahore. Sequential dilutions were made with distilled water. Eggs were taken from local hatchery and divided into 4 groups. Each group was comprised of five eggs. The eggs were incubated at 37 C0. At day 4, 3-4 ml albumin was removed with the help of syringe. At day 5, sample solutions of various concentrations were applied to chorioallentoic membrane (CAM). After 24 hours, the change in CAM was observed by taking the images. SPIP was utilized for computerized measurements of the diameter of blood vessels and CAM. Overall area of the CAM was also drastically minimized among all groups treated with sample solutions.
The data was analyzed for statistical analysis by using SPSS software (version 13 for windows). ANOVA was performed to determine significance among different groups. The value of P<0.05 was considered as significant.
Different extracts of Eugenia Jambolana exhibited anti-angiogenic potential in the following order. WS > WL = ES > EL. In case of WS 4% solution area of CAM is 285.66 mm2, WL 4% 586.77 mm2, ES 4% 567.47 mm2 and EL 4% 634.23 mm2 while in case of negative control area of CAM 2473 mm2 . The extracts exhibited anti-angiogenic potential in variable magnitude. Dilutions of water extract of seeds exhibited most anti-angiogenic potential (p<0.01) in comparison to other treated groups. Collectively, these observations show that extract of Eugenia jambolana seeds and leaves contains polar compounds that ceased growth, primary vessel formation and cell propagation in CAMs.

Publisher: 2013Dissertation note: Pakistan has been bestowed with a huge population of livestock encompassing buffalo, cattle, sheep, goat, camel and other domestic animals such as cats, dogs, rabbits, etc. Out of these, dogs occupy a special attention due to many peculiarities they possess like sniffing, hunting, retrieving and many more. These specialties of dogs are utilized by military, rangers, police, anti-narcotic forces, other agencies, etc. There are three million dogs in Pakistan. A dog encounters many infectious and non-infectious diseases during the course of its life cycle. Some of the viral infectious diseases, and considered more important for a dog are, rabies, canine parvovirus infection, canine distemper, and infectious canine hepatitis. As a pathogen, canine parvovirus emerged in 1970s but later it evolved into two new antigenic strains, type 2a and type 2b which are distributed all over the world. Mostly, protection against CPV is gained from maternally derived antibodies in puppies but simultaneously they may interfere with CPV vaccination. Severe gastrointestinal signs are associated with CPV and this infection is transmitted through contact with infected feces via oro-fecal route or exposure with fomites and also via placental transmission. The virus is very stable in the environment and is susceptible to some cleaning agents like bleach.
The current study was conducted to study the descriptive epidemiology of canine parvovirus disease in dogs at Pet Center, University of Veterinary and Animal Sciences (UVAS) in Lahore and to compare two types of hyper immune sera i.e. Canglob (Ghazi Brothers) and UVAS hyper immune serum for parvovirus through interventional trial, for treating the clinically diseased pups. The study included puppies aged between six weeks and six months. Puppies aged between six weeks and six months, found clinically suspected to be affected with canine parvovirus and showing the signs and symptoms like vomiting, bloody mucoid diarrhea, emaciation and anorexia and found positive for hemagglutination test were included in the study. Hemagglutination test was used as a diagnostic and a screening test to confirm canine parvovirus in the clinically suspected puppies.
The disease was more observed in the puppies aged between 7 to 12 weeks. There were 28 females and 32 males observed in the study. The disease was more frequently observed in Labradors. The disease was observed to be more common in the dogs that weighed 4-6 kgs. Canine parvovirus HA titers were more observed in the dogs that had been ill due to CPV for the past 5-6 days. Only 16 puppies out of 60 were vaccinated. Also, it was observed that canine parvovirus geometric mean titer was higher in the non-vaccinated puppies. The disease was more observed in the pups vaccinated with a polyvalent vaccine and less observed in the pups that were inoculated with a monovalent vaccine. Most of the dogs were aged between 31-60 days when they got vaccinated. Sixty percent (60%) of the dog owners knew that if vaccination is done then the dog may be protected against the disease. The disease was more observed in the pups that were owned by more educated and economically stabled persons.
The result of the statistical analysis using Pearson Chi-Square Test suggests that the difference between Group A and Group B regarding the outcome of the interventional trial is not statistically significant. Therefore, the hypothesis is accepted that the UVAS produced hyper immune serum against canine parvovirus is equally good as compared with Canglob for the treatment of CPV diseased puppies.

Publisher: 2013Dissertation note: Plant products play an important role because of their medicinal activity. A wide variety of active phytochemicals peptides have been found to possess therapeutic applications against various functionally and genetically diverse viruses. Influenza A viruses (IAV) causes acute respiratory diseases in humans, birds, and other mammals, representing one of the major threats to public health.
In this study, the antiviral activity of Allium sativum L., Allium cepa L., and Zingiber officinale Roscoe against Avian Influenza H9 virus was evaluated in ovo. The aqeous extracts of Allium sativum L., Allium cepa L., and Zingiber officinale Roscoe were prepared by using macerate technique. From the macerate, nine different dilutions i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml of the extracts were prepared in normal saline. For each plant extract; Allium sativum L., Allium cepa L., Zingiber officinale Roscoe 100 embryonated chicken eggs were assigned to 20 groups, each group containing 5 embryonated chicken eggs (nine for antiviral activity, nine for cytotoxic activity, and two groups were kept positive and negative control respectively) and marked them with lead pencil. The different concentrations of the plant extracts were mixed with virus and 0.2 ml inoculum was inoculated to 9th to 10th day embryonated chicken eggs along with positive and negative controls containing only virus and normal saline respectively. The embryonated chicken eggs were incubated at 37oC and were checked after 12-72 hrs. After 72 hr post inoculation, all the eggs were chilled in refrigerator at 4oC for 12 hrs and the allantoic fluid was harvested. The antiviral activity was calculated as embryo survival percentage, positive or negative spot Hemagglutination activity and determination of virus titre by Hemagglutination Test. The cytotoxicity of Allium sativum L., Allium cepa L., Zingiber officinale Roscoe extracts was evaluated by only inoculating the extracts of respective concentrations as used for antiviral activity in embryonated chicken eggs and incubating for 72 hrs. The results were analyzed by ANOVA by means of SPSS.
All the concentrations of Allium sativum L. were non toxic while three concentrations showing antiviral activity were 8000 ƒÊg/ml, 4000 ƒÊg/ml and 2000 ƒÊg/ml. While in case of Allium cepa L. all the concentration i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml were non cytotoxic and five concentrations i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml and 500 ƒÊg/ml show potent antiviral activity. In case of Zingiber officinale Roscoe two concentrations 8000 ƒÊg/ml, 4000 ƒÊg/ml were virucidal and all concentration 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml were non cytotoxic. So the present study suggested the presence of antiviral activity of plant extracts of Allium sativum L., Allium cepa L., Zingiber officinale Roscoe, so they can be used for prevention and treatment of various viral diseases.

Publisher: 2014Dissertation note: Background
Opportunistic pathogens represent the type of pathogens which infects only those individuals
with impaired immune system and lead to diseases that can be severe, debilitating and difficult to
treat in immunocompromized host. These opportunistic pathogens include different bacteria,
viruses and fungi. This study was designed to identify the opportunistic bacterial pathogens
pseudomonas and Citrobecter in immunocompromized chronic liver disease (CLD) patients.
This study was performed to analyze sensitivity pattern of bacterial pathogens to commonly used
antibiotics quinolones, aminoglycosides, cephalosporin and co-trimoxazole and to evaluate the
synergistic efficacy of different combination s of antibiotics. The study was conducted on
different CLD patients admitted in different medical wards of Sir .ganga Ram Hospital Lahore.
Aim
By using blood and urine culturing technique and different biochemical tests opportunistic
pathogens Pseudomonas and Citrobecter in CLD immunocompromized patients belonging to
different age group were determined. Combination therapy of quinolones, aminoglycosides,
cephalosporin and sulpha drugs were effective against the bacterial pathogens Pseudomonas and
Citrobecter.
Material and Methods
Clinical sign and symptoms of all the CLD patients who were admitted in the hospital were
noted at the time of admission The patients who start showing sign and symptoms (Fever,
burning micturation, pain) of suspected infection on 2nd and 3rd day of their admission were
included in this study. Blood and urine samples were collected from infected CLD patients with

SUMMARY
suspected sign and symptoms by using all necessary aseptic precautions with the assistance of
trained professionals. The pathogens were isolated, identified and purified by selective culturing
methods, which were subjected to active growth, during which sensitivity to different antibiotics
was checked. Antibiotic sensitivity test was conducted on pure culture isolates employing the
Kirby Bauer disc diffusion method for the commonly used antibiotics. The diameters of growth
inhibition around the discs was measured and interpreted by using Clinical Laboratory Standards
Interpretations (CLSI).
Statistical Analysis
The collected data was analyzed by ANOVA and Chi-square test on SPSS software (16) .
Results
Pseudomonas and Citrobecter pathogens are now proved to be a multi resistant pathogens and
use of combinations of antibiotics against these pathogens found to be more effective. This study
was performed to evaluate the synergistic effect of different antibiotics combinations against
Pseudomonas and Citrobecter pathogens, so that the chances of recurrent infections among the
immunocompromized hospitalized patients were minimized. It will help to improve the quality
of life of immunocompromized patients through providing information about effective antibiotic
treatment. The effects of different combinations of antibiotics were also analyzed in CLD
patients through evaluating the improvement in infectious disease. It was found during study that
combination of ceftriaxone and amikacin prove to be more effective in clinical settings but in
vitro studies shows the combination of cephradine with gentamycin was 97% susceptible.

Publisher: 2013Dissertation note: Background: Sepsis is the presence of bacteria in blood. Neonatal sepsis indicates bacterial blood stream infection (BSI), such as gastroenteritis meningitis, pyelonephritis, pneumonia which results in fever in neonates (Weber et al. 2003). This study was designed to check the bacteriology and sensitivity pattern of microbes causing sepsis in neonates. In this study microbial susceptibility testing against antibiotics and pattern of resistance of microbes in septic patients was determined. It was conducted on neonates suspected from sepsis in Sir Ganga Ram Hospital Lahore, Pakistan. Hypothesis: By using blood cultures and different biochemical tests bacterial etiological agents of neonatal sepsis were determined and their sensitivity pattern and empirical therapies were evaluated. Material & Methods: Blood samples were collected from septic neonates admitted in Sir Ganga Ram Hospital keeping all necessary aseptic precautions with the assistance of trained professionals. The pathogens were isolated, identified and purified by selective culturing methods, which were subjected to active growth, during which sensitivity to different antibiotics were checked. The sensitivity was measured by area marked by the zone of inhibition, and National Committee for Clinical Laboratory Standards (NCCLS). Standard limit was a key indicator towards resistant bacteria. Statistical Analysis: The collected data was analyzed by appropriate statistical procedure. Outcome: It was designed to isolate and identify the pathogens responsible for neonatal sepsis and to see the effects of different antibiotics regimens for treatment of neonatal sepsis by evaluating the improvement in clinical condition, rate of complications of disease and incidence of death due to this fatal disease.
