Publisher: 2012Dissertation note: The fasciolosis in sheep and goat is an important and infectious disease of ruminants characterized by dullness, weakness, lack of appetite, pallor and edema of mucosa and death of animal. The accurate diagnosis of Fasciolosis remained a difficult task for the field practitioners and the right choice of medicine.
For this purpose 600 sheep and goats was examined for fasciolosis. The fecal samples were collected directly from rectum while bile samples were collected from various private and public slaughter houses of districts Okara, Sahiwal and Lahore. Fasciola egg was identified by standard text while molecular conformation of Fasciola spp. was done by using PCR. For therapeutic trials, sixty animals (n=30 sheep; n=30 goats) positive for Fasciolosis was equally divided into A, B and C groups and each group comprising of 20 animals (n=10 sheep; n=10 goats). The animals of group A was given Zanil (Oxyclozanide) orally @ 1ml per 3kg body weight; the animals of group B was given Albendazole orally @ 1ml per 3kg body weight and the animals of group C was given the grounded powder of Neem leaves (Azadirachta indica) @ 5-6 teaspoon (25-30gm) orally. Efficacy of drugs was measured on the basis of disappearance of Fasciola eggs at 3, 7 and 14 day of post-medication. Data on the prevalence of fasciolosis was analyzed by Pearson's chi-square test while therapeutic trials data was analyzed with one way ANOVA using Statistical Package for Social Sciences (SPSS); P < 0.05 was considered significant.
To study fasciolosis in sheep and goats, samples were collected from Lahore, Okara and Sahiwal. The collected samples were processed at the Medicine laboratory at UVAS, Lahore and LPRI laboratories of Bahadurnagar, Okara. In this study first of all the fecal and bile samples were examined through microscope then these samples were processed by PCR test. No study was conducted previously on the molecular diagnosis of fasciolosis in sheep and goats in Pakistan, this is the first report for the molecular diagnosis of fasciolosis. In all F. hepatica positive samples approximate 300-bp fragment was generated on gel tested with DSJF/DSJ3 primers for sheep and goats. All positive samples by microscope were also positive by PCR, but out of the 92 samples positive (43 in sheep; 49 in goats) by PCR test, out of these 14 (7 in sheep; 7 in goats) were negative by microscopy. This study provides the base line data for the molecular diagnosis of fasciolosis in sheep and goats in Pakistan.
Overall prevalence of fasciolosis in sheep in both fecal and bile samples in various districts of Punjab was calculated. Out of 300 samples (150 fecal; 150 bile) of sheep, F. hepatica prevalence rate was 12% (36 samples) by microscopic examination while 14.33% (43 samples) by PCR test. On the basis of microscopic examinations districts wise prevalence rate was 11, 12 and 13% in Lahore, Okara and Sahiwal respectively and by PCR test prevalence rate was 13, 14 and 16% in Lahore, Okara and Sahiwal respectively. Prevalence of F. hepatica was more in Sahiwal than Okara and Lahore in sheep in both fecal and bile samples on the basis of microscopic examination and PCR.
Overall prevalence of fasciolosis was also calculated in goats on the basis of microscopic examination and PCR in both fecal and bile samples. Among 300 samples (150 fecal; 150 bile) of goats F. hepatica prevalence was 14% (42 samples) by microscopic examination while 16.33% (49 samples) by PCR. On the basis of microscopic examinations the prevalence was 13, 15 and 14% in Lahore, Okara and Sahiwal districts respectively while on basis of PCR test prevalence was 15, 18 and 16% in Lahore, Okara and Sahiwal districts respectively. Prevalence of F. hepatica was more in Okara than Sahiwal and Lahore in goats in both fecal and bile samples on the basis of microscopic examination and PCR.
The eggs per gram (EPG) values and efficacy of Oxyclozanide (Zanil), Albendazole and Neem leaves against fasciolosis in 30 positives sheep was recorded at 3, 7 and 14 days after the treatment. As group A was treated with oxyclozanide (Zanil), its efficacy was 50, 75 and 90% at 3rd, 7th and 14th day respectively after treatment. The efficacy of albendazole was 46, 65 and 81% at 3rd, 7th and 14th day respectively while the efficacy of Neem leaves was lowest that was 15, 30 and 42% at day 3rd, 7th and 14th day respectively. The efficacy of oxyclozanide and albendazole was significantly higher (p= 0.000) than Neem leaves. In sheep against the fasciolosis Oxyclozanide significant effect on EPG followed by albendazole and Neem leaves.
The EPG and efficacy of Oxyclozanide (Zanil), Albendazole and Neem leaves were determined in 30 goats against fasciolosis at 3, 7 and 14th day of post treatment. The efficacy of oxyclozanide was 57, 76 and 90% at 3, 7 and 14th day of post treatment, respectively. The efficacy of oxyclozanide was higher than Albendazole against the fasciolosis. The efficacy of albendazole was 55, 68 and 79% at day 3, 7 and 14th, respectively. Efficacy of Neem leaves against fasciolosis was lower as compared to other two drugs, it was 15, 23 and 40% at day 3, 7 and 14th, respectively. When the efficacy was compared at different days, Oxyclozanide reduced the EPG significantly, followed by Albendazole and Neem leaves.
From this study it was concluded that PCR is more reliable technique than microscopic examination for the diagnosis of fasciolosis in sheep and goats. Microscopic technique provides the base line data for the diagnosis of fasciolosis in sheep and goats but PCR provides help to conduct further molecular diagnosis on fasciolosis as well as others parasitic diseases. Secondly fasciolosis which is an important parasitic problem of ruminants is significantly prevalent in sheep and goats in Lahore, Okara and Sahiwal districts of Punjab. Oxyclozanide is the most effective drug while albendazole and neem leaves (Azadirachta indica) are relatively less effective against fasciolosis in sheep and goats.

Publisher: 2012Dissertation note: Theileriosis is an infectious malady of equidae characterized by intermittent fever, loss of appetite, anemia, loss of weight, dyspnea, pale mucous membranes, jaundice and recumbency. Considering the significance and utilization of equines in our country and the substantial losses rendered by theileriosis, the present study was designed to study prevalence and chemotherapy of theileriosis in equines in and around Lahore.
For this purpose 300 equines (Horses=100; mules=100; donkeys=100) were examined for theileria infection.The blood was collected by ear tip puncture and from Jugular venipuncture. Then thin blood smear slide was prepared and dried up in air and stained with Geimsa's staining method and examined under microscope. Theileriaequiwere identified by their morphological characteristics as described by Rashid et al. (2009) and Guimaraeset al. (1997).Over all prevalence of Theileriaequiin equines was estimated as 58%. There was also a mixed infection of Theileriaequi and Babesiacaballiin some cases. Individually there was 54%, 64% and 56% prevalence of Theileriaequi found in horses, mules and donkeys respectively.
The effect of theileriosis on various blood parameters (Hb, ESR, TEC, TLC, DLC and PCV) was determined in 30 equines (Horses= 10; mules= 10; donkeys= 10). The remarkable decrease in hemoglobin, TEC, PCV and lymphocytes was observed. The value of ESR increased while there were no remarkable changes in TLC, monocytes, basophils, neutrophils and eosinophil.
For chemotherapy, 36 equines (Horses=12; mules=12; donkeys=12) positive for theileriosiswere divided into three groups (A, B, and C). Each group was further subdivided into three subgroups comprising of 4 animals in each subgroup. The animals of group A (Horses=4; mules=4; donkeys=4) were treated with Imidocarbdipropionate (Imizol®, ICI, Pakistan) @ 2 mg/kg BW I/M, and the efficacy of drug was found 91.7% in equines against theileriosis.The group B (Horses=4; mules=4; donkeys=4) was treated with Buparvaquone (Butalex®, ICI, Pakistan) @ 2 mg/kg BW I/M alone and was observed 66.7% effective. While the group C (Horses=4; mules=4; donkeys=4) was treated with Auk(Calotropisprocera)@ 0.3mg/kg BW, 8 doses at alternate days (local treatment), which was found 58.3% effective. The efficacy of drugs was measured on the basis of disappearance of clinical signs and blood smear examination at day 2, 4, 6 and 10 of post-medication. The efficacy of each drug was measured through recovery rate of the animals.
Finally, the data on prevalence of theileriosis was estimated by Pearson's chi-square test for significance whereas data on hematology was analyzed by Student's T-test using statistical software package STATA 9.1 (College Station T×77845, USA), P < 0.05 was considered significant.
Considering the significance and utilization of equine in our country and the substantial losses rendered by theileriosis, the present project was designed to check prevalence and chemotherapy of theileriosis in equines in and around Lahore. The results of this study will help farmers and veterinary practitioners in field.

Publisher: 2013Dissertation note: Trypanosomiasis is an infectious malady of equines characterized by weight loss, anemia, progressive paresis, enlarged lymph nodes, petechiae of serous membranes, conjunctivitis, edema of the legs and lower part of the body, urticaria, and alopecia. Considering the significance and utilization of equines in our country and the substantial losses rendered by trypanosomiasis, the present study was designed to study prevalence and chemotherapy of trypanosomiasis in equines of Gujranwala and Sialkot districts.
For this purpose, 300 equines (horses=100; mules=100; donkeys=100) were examined for Trypanosoma infection. The blood was collected by ear-tip puncture and from Jugular venipuncture. Then thin blood smear slide was prepared and dried up in air and stained with Geimsa's staining method and examined under microscope. T. evansi was identified by their morphological characteristics as described by Smyth, (1996). Overall prevalence of T. evansi in equines was estimated as 13%. Individually there were 16%, 13% and 12% prevalence of T. evansi found in horses, mules and donkeys respectively.
The effect of trypanosomiasis on various blood parameters (Hb, ESR, TEC, TLC, DLC, and PCV) was determined in 30 equines (horses=10; mules=10; donkeys=10). The remarkable decrease in Hb, TEC, PCV, and lymphocytes were observed. The value of ESR increased, while there were no remarkable changes in TLC, monocytes, basophils, neutrophils, and eosinophils.

Publisher: 2014Dissertation note: Pakistan being an agriculture country has 70% of its population that is totally dependent on agriculture and livestock sector which plays an important role in the economy of the country. Livestock has contribution of about 55.4 percent to the agricultural value added and 11.9 percent to the National GDP. Pakistan has population of about 64.9 millions of goat, 38.3 millions of cattle, 33.7 millions of buffaloes and 28.8 millionsheep population according to the economic survey estimate. Mutton production is about 643 million tons and beef production is about 1,829 tons out of total 3,379 million tons of meat production. Livestock produces approximately 49,512 million tons of milk out of which buffalo produces 62.0% while cattle produces 35% and sheep-goat produces 1.69% (Economic Survey, 2012-2013). Pakistan is the 3rd largest milk producing country in the world (Afzal, 2010).
Diarrhea can be defined as an increased in volume and quantity of fecal excretion. The diarrhea may contain mucous, blood, poor odor and variation in color then the normal feces.On the basis of time period, diarrhea has different types likeacute, constant and chronic. Time Period of acute diarrhea is not more than 14 days while in case of persistent/constant form, it continued for more than 14 days and in chronic case the diarrhea remain for a time period of 28 days(Bazeley, 2003)
Diarrhea is a leading factor towards the death of calves. Neonatal calf diarrhea is among the very important diseases of the calves worldwide. It is animportant contribution to the major economic losses in cattle industry. The cause of calve diarrhea may be infectious or non-infectious (Elhassan et al. 2011).
Bad hygiene, overpopulation, overfeeding, hot/cold temperature, feeding the calves artificially and the colostrum’s deprivation are all predisposing factor in the complex etiology of the disease (Hemashenpagam et al. 2009).
Infectious agent and the co-infection of different multiple pathogens are common in calves having diarrhea. Rotavirus, Cryptosporidium, corona virus and enterotoxigenicE. coli collectively are associated with 75-95% of the infections in calf diarrhea around the world. Clinically, Neonatal calf diarrhea is characterized by profuse acute watery diarrhea, progressive dehydration, acidosis and death within a few days. The degree of dehydration is estimated by the physical examination of calf and has been introduced as a reliable method (Radostits et al. 2009).
Experimentally the intestinal potassium and sodium combination can be bothered by different causes and various types of factors. However, electrolytes that are built up in the gastrointestinal tract have a function to reduce the water assimilation. Due to this, the organism losses water and the electrolyte commonly (Smith, 2009)
To evaluate the serum electrolytes as well as the acid-base imbalance, there is a need of laboratory tests which cannot be measured regularly in field condition.To check the degree of dehydration is a uniform protocol and is anticipated by body condition score of calves (Naylor 1989).
The electrolytes deficiency in neonatal diarrheic calves might be the cause of death in some cases. Althoughit is understood that serum concentrations of potassium (K) and sodium (Na) are very much necessary with reference to the fluids composition used for treatment purpose (Rucker et al. 2008).
Trace elements have also important part inthe reproduction, growth and productivity of the householdanimals. The imbalance and Difference in ratio of minerals leads towards both production and economic losses throughout the world. The important symptoms of trace element deficiencies that can be clinically shown in animals are anemia, diarrhea, loss of hair, pigmentation loss, growth disorders in bones, difficulty during walking, a flaky deposit in skin, bending, hyperkeratosis, Para keratosis, lack of appetite, decrease in reproductivity and fertility, young animal growth disorders, Tetany, reduction in protein synthesis, immunity compromised calves, abortion related to non-infectious factors and pica. However, reduction in the concentration of trace elements like cobalt, copper, iron, iodine, manganese, selenium or zinc leads to lower reproduction rates and lactation. Untreated changes in the serum concentrations of Ca, Mg and some trace elements may be the root of cause of some death or post diarrhea complications such growth retardation (Tajik and Nazifi, 2012).
The serum values of calcium (Ca) and magnesium (Mg) that is abnormal persists for a significantly long duration after the treatment of neonatal diarrheic calves. The normal serum concentration of Ca in cow has been reported as 2.43-3.1 mmol/L while the mean serum Ca in diarrheic calves reported was 1.297mmol/L. The normal serum concentration of Mg in cow has been reported as 0.74-0.95 mmol/L while the mean serum Mg was reported to be 0.8145mmol/L (Kaneko et al. 2008).
There are many advantages of using the hypertonic saline solution (7.5% NaCl; 4ml/kg BW) in diarrheic buffaloes and cattle to resuscitate them. Infusion of Hypertonic saline solution resulted in significant increase in sodium and chloride level in serum. The important feature for the successful and complete resuscitation of hypovolemia along with endotoxaemia in diarrheic buffalo calves is the total amount of sodium. The infusion of Hypertonic saline solution is quite safer and it does cause hypernatremia but not for a prolonged period. So, hypertonic saline solution has advantage of resuscitating the calves from acidemia and hypovolemia. It was also helpful in the improvement of oxygenation and cardiovascular performance (Zafar et al. 2012).
The neonatal calf diarrhea can be cured by using the electrolyte therapy like ringer lactate, non-steroidal anti-inflammatory medicines and antibiotics in case of infectious diarrhea and through better farm management depending upon the root of cause (Radostits et al. 2009). There is a hypothesis that treatment of diarrheic calves with NSAIDs attenuates the behavior of sickness as well as gastrointestinal discomfort and encourages the calves to maintain an appetite supports the calves for better performance (Ghanem et al. 2012)

Publisher: 2015Dissertation note: Agriculture sector plays a pivotal role in the economy of Pakistan. At present it
participates 11.4% to GDP. Agriculture provides 45% employment to labour of our country
and contributes in the development of other sectors of the economy. The livestock sector
occupies a distinguishing position in the National Agenda of economic development. It
provides net source of foreign income. In the history livestock has been dominated by small
holders to meet their needs of milk, food safety and cash earnings on daily basis. Besides,
livestock is considered a source of employment generation at rural level. It plays an important
role in poverty mitigation and keeps in elevating the socio-economic situation of our rural
commonalities. Livestock share approximately 55.4 percent to the agricultural value added
and 11.9 percent to national GDP during 2013-14. Anonymous (2013-14).
Parasitism is one of the major problems lowering livestock productivity round the
earth Vercruysse and Claerebout et al. (2001). The significance of helminthes infections is
increased manifold in developing countries like Pakistan where 65.2% population is rural
(Population Census Organization (2007) depending upon livestock for their incomes and
where parasitism acts as a serious trouble for livestock economy Chaudhry et al. (1984).
Among helminthes infections, fasciolosis commonly called as liver fluke disease is of vital
importance due to its wider spectrum of ultimate hosts Rondelaud et al. (2001) causing acute
and chronic infections Sampaio-Silva et al. (1996). The disease is primarily caused by
Fasciola hepatica and Fasciola gigantica Soulsby et al. (1987). Fasciolosis is a parasitic liver
infection of wild and domestic ruminants caused by genus Fasciola, which has worldwide
distribution Soulsby et al. (1986). Fasciolosis causes economic losses as a result of
mortalities, abortions, retard growth, reduced milk and meat production, condemnation of
infected liver and emaciated carcasses and cost of animal treatment Gracey and Collins et al.
(1992). Fasciolosis caused by F. hepatica is a cause of important economic losses in
ruminants. The disease is widely spread throughout in Africa, Asia and the Pacific. Although
mostly a problem of young stock, the disease is also found in older animals where it
adversely affects health, growth rate and development. Apart from its great veterinary
importance throughout the world, fasciolosis caused by both F. hepatica and F. gigantica has
recently been shown to be a re-emerging and wide spread zoonosis affecting a number of
human populations Mas-Coma and Bargues et al. (1997); Esteban et al. (2003).
Prevalence of fasciolosis infestation in buffaloes is 49.01%. The infestation of
fasciolosis was optimal from January to September, while least during October to December.
Fecal samples indicated F. hepatica prevalence 65%. Whereas prevalence of F. gigantica
was observed higher in adult cattle as compared to cattle calves by fecal egg counts Khalil et
al. (2009). 4% Buffalo calves infested with trematodes. Availability of intermediate host and
the grazing habits of the final host determines the epidemiology and seasonal pattern of
infection with trematodes Pfukenyi et al. (2005); Bhutto et al. (2002). The life cycle of F.
hepatica includes many stages which develop in the environment or the intermediate host.
Metacercariae which is the infective stage encysted and ingested by grazing herbivores.
Temperature and rainfall are the important factors affecting the life cycle and the prevalence
of F. hepatica infection McCann et al. (2010). Many studies revealed that F. hepatica is
endemic in buffaloes, cattle, goats, sheep and humans in Pakistan Ijaz et al. (2009); Iqbal et
al. (2007); Khan et al. (2010) and Qureshi et al. (2005).
Fasciolosis is the disease by which about 250 million sheep and 300 million cattle are
potentially affected worldwide Boray et al. (2005), and more significantly infects all
ruminants Iqbal et al. (2007). F. hepatica and F. gigantica are the two liver flukes commonly
reported to cause fasciolosis in ruminants Walker et al. (2008). Infected cattle can exhibit

poor weight gain and dairy cattle have lower milk yield, and possibly metabolic diseases
Mason et al. (2004). Losses due to fasciolosis in the United Kingdom and Ireland alone are
more than ￡18 million a year Mulcahy and Dalton et al. (2001); €52 million a year or €299
per infected animal in Sweden Schweitzer et al. (2005); 0.26 million USD annual due to
fasciolosis associated liver condemnations in cattle slaughtered in Kenya Kithuka et al.
(2002). In Pakistan, 35697 USD (3141360 PKR) are reported in only one tehsil of Punjab
province, the Sargodha T.U. Rehman et al. (2013). While Fasciolosis is prevalent in whole
Punjab province of Pakistan but the marshy areas such as regions of Gujranwala, Lahore,
Multan, Faisalabad, Jhang, Muzaffargarh, Sheikhupura, and Sargodha are of major concern.
Fascioliasis in ruminants causes substantial economic losses, estimated at US$ 2
billion per annum worldwide, to rural agricultural communities and commercial animal
producers due to death of infected animals, condemnation of affected livers and production
losses associated with reduced feed conversion efficiency Urquhart et al. (1996); Spithill and
Dalton et al. (1998). In tropical countries, fascioliasis is prevalent up to 90% and is
considered the most important helminthes infection of cattle Spithill and Dalton et al. (1998).
Most important, human can also become infected with Fasciola spp. and the disease is
referred to as human fasciolosis. It is estimated that 2.4 million people in more than 60
countries are infected and the number of people at risk is more than 180 million throughout
the world Haseeb et al. (2002); Mas-Coma et al. (1999); Ishii et al. (2002). Khalil et al.
(2009) recorded 49.01% prevalence of fasciolosis infestation in buffaloes. He also observed
that optimum infestation was seen from January to September, while minimum during
October to December. Whereas Bhutto et al. (2002) recorded 4% buffalo calves infested with
trematodes.

Morphological identification of Fasciola species requires significant parasitological
skills and is not an accurate method of characterization, especially for the ‘intermediate’ form
Kendall et al. (1965); Lin et al. (2007); Le et al. (2008). Hence, different molecular tools have
been developed during the last decade for the accurate identification of Fasciola spp.
Marcilla et al. (2002); Velusamy et al. (2004); Cucher et al. (2006); Magalhaes et al. (2008);
Ai et al. (2010). Conventional techniques like fecal examination used for its diagnosis are not
comprehensive because of Species similarity in distribution in many countries of East and
North Africa, and Southeast and Central Asia, and are similar in egg morphology.
Coprological methods continue to be the most widely used approach for the detection and
quantification of Fasciola and other helminth eggs in laboratory animals, domestic and
sylvatic animals and humans Cringoli et al. (2004, 2010); Bergquist et al. (2009), with a more
recently developed method that is currently undergoing broad-scale validation the FLOTAC
techniques Cringoli et al. (2010) for the detection and quantification of F. hepatica eggs in
feces obtained from experimentally-infected rats before and after drug administration.
FLOTAC has been used successfully in the diagnosis of F. hepatica infections in naturallyinfected
sheep, which underwent treatment with standard Cringoli et al. (2006). However
PCR based diagnosis using specie-specific primers has been proved more accurate and
successful in diagnosis and distinction of Fasciola species Le TH et al. (2012). The molecular
technique such as PCR is used for the recognition of parasite. These molecular techniques are
largely accepted all over the world. These are more exact methods than traditional in
epidemiological studies Heckeroth and Tenter et al. (1999).
Herbal drugs have been used since ancient times to cure diseases and medicinal plants
have been used to treat fasciolosis among these Nigella sativa and Allium sativum have been
used to treat the worm infestation. No report of resistance development to plant anthelmintic
although many have been used in veterinary medicine for many years Ashaal et al. (2010);

Publisher: 2015Dissertation note: Gastrointestinal helminths are responsible for wide range of health problems, economic losses in camels and are characterized by impaired milk, meat, infertility, low calving rates, decreased working efficiency and even death of the camel.
To study the gastrointestinal helminths, 384 camels of different age, sex and breed was examined coprologically. For this, five gram of fresh fecal sample was carefully collected into a sealed container from each camel and was transferred to Medicine lab, UVAS, Lahore in containers with ice packs. Fecal samples were scored 1-3 based on the consistency. The individual samples was triturated in saturated salt solution, sieved and examined for helminths eggs by using different techniques i.e. Direct Smear Method, Sedimentation technique and Floatation technique while the eggs count was performed by McMaster technique. Among the camel population, the current study indicates that in Marrecha breed the prevalence of Nematodes was Trichostrongylus 1.77%, Haemonchus 8.44%, Nematodirus 3.11% and Trichuris 7.11% respectively. Mixed infestation of all the nematodes was found 26.66% in infested camels, while the prevalence of Camelostrongylus, Trichostrongylus, Strongyloides, Haemonchus, Nematodirus and Trichuris in Barella breed was 4.40%, 1.88%, 2.51%, 6.91%, 2.51% and 7.54% respectively.

To study the effect of gastrointestinal helminths on various blood parameters of camels, blood samples were collected from 5 infected and 5 healthy camels. Samples were analyzed using Hematology Analyzer and results were compared.
For therapeutic trials, a total of 30 camels positive for helminths was taken and divided into three groups A-C each group comprising of 10 animals. A fourth group D was selected comprising of 10 uninfected camels. The camels of group A were treated with dry Neem (Azadirachta indica) leaf powder at a daily oral dose of 100 gm/camel for five days, group B was treated with Albenzole granules® (Albendazole) at a dose rate of 15mg/kg bd. wt. PO once. Group C (untreated) was designated as positive control, and the camels in Group D as negative control. Efficacy was determined on the reduction of eggs in feces at day 3, 7 and 14 (post-treatment). In the current study Neem leaves and Albendazole gave following results in the camels affected with Helminths. Neem leaves cured 20% of the animals on day 3rd after the drug administration while 40% and 60% of the animals cured on the day 7th and 14th respectively. Albendazole also gave good results against helminths affected camels. On the day 3rd of the treatment 30% animals cured while 60% animals were cured on the 7th day and on 14th day 80% animals recovered.
Data regarding prevalence was measured by non-parametric, chi-square (χ2), while therapeutic trails were analyzed by repeated measures one way ANOVA, using SPSS (Statistical package for social sciences), P < 0.05 was considered significant.

Publisher: 2015Dissertation note: Dogs are one of the most commonly owned companion pets worldwide. They are kept for various factors such as hunting, guarding, and amusement or for animal assisted therapy. Tick infestation is a common problem in dogs and its transmitted infections usually tick borne hemoparasitic diseases are emerging as a worldwide problem not just for animals but also for humans. Due to this phenomenon, ticks are now recognized as a major cause of various diseases in of urban environments. The current research has been conducted to study the prevalence of tick infestation, associated risk factors and chemotherapeutic trials of topical acaricides were used in order to study comparative efficacy, were conducted in dogs. Furthermore, prevalence of tick borne hemoparasitic diseases was also observed by performing microscopic blood smear examination in dogs of Lahore district.
A total of 300 dogs (n= 200 positive for tick infestation; n= 100 negative for tick infestation) having tick infestation were included in the present study. Dogs of different sex, age and breed were selected for tick collection. The ticks were collected with the help of forceps from the target sites of each dog, while adopting all necessary measures to avoid damage to the mouth parts of the ticks and skin of the host. The collected ticks were preserved in plastic containers containing 70% ethanol, which was separate for each specimen. Ticks were identified under stereoscope by observing morphological characteristics of each tick, according to the key. Blood sample for tick borne hemoparasitic diseases was drawn from cephalic vein of each dog using disposable syringe and was poured into EDTA vacutainer. Thin blood smear slide was then prepared from the blood of the animal, dried in air and was stained using Geimsa’s staining method. The hemoparasites observed in the blood of the dogs were then characterized and

identified by their morphological characteristics. For chemotherapy, a total of 30 tick infested dogs of different breeds viz. Rottweiler, German shepherd and Labrador was used in therapeutic trials. Each breed of dog was divided into 2 subgroups which were then treated with topical ivermectin and fipronil 1500μg/kg b.w and 15mg/kg b.w respectively. Efficacy of the drugs was then measured on the basis of disappearance of clinical signs and reversal of tick infestation at day 2, 4 and 6 of post-medication. Data regarding the prevalence of tick borne hemoparasitic diseases and tick infestation was analyzed by using Non-parametric, Chi-square test whereas data on therapeutic trials was analyzed by Z-test, using statistical package for social science (SPSS). P < 0.05 was considered significant.
The results obtained showed us that the study area is at a risk of tick infestation and tick borne hemoparasitic diseases. In dogs, Rhipicephalus sanguineus (brown dog tick) species was observed and identified as a major tick infesting dogs of the study area during the course of study. Various determinants including tick density and its genus, host age, sex, predilection site host breed and season significantly affected the tick infestation in the study area. The prevalence for tick infestation was found highest in Pastoral dogs as compared to other breed types found in dogs. Among breeds German shepherd showed highest prevalence for tick infestation. Adolescence age group among dogs was more prone to tick infestation. The number of males affected by ticks was highest as compared to females in dog population. Among the dog population, majority of the animals infested by ticks were categorized under mild infestation. The most favorable predilection site for tick infestation in dogs was ear pinnae, followed by head and then neck. Monsoon was the most favorable season for tick infestation in dogs. September was found to be highest favorable month for tick infestation in dogs.
Summary

In tick borne hemoparasitic diseases, babesiosis was the highest prevalent disease in dogs (63.33%), followed by trypanosomiasis (0.66%) and mixed infection (0.33%). Age group among dogs showed non-significant factor affecting prevalence for TBHD’s. The number of affected dogs for babesiosis was greater in adolescence age group as compared to other age groups. On the other hand, trypanosomiasis and mixed infection adult age group was found highly susceptible. Males of canine group were slightly more susceptible than females in case of babesiosis. Similarly for trypanosoniasis and mixed infection males were more prone than females. For babesiosis, monsoon was the most favorable season in dogs. Whereas for trypanosomiasis and mixed infection, post monsoon was found to be favorable season in dogs. In breed type of dogs, prevalence for babesiosis was found highest in Pastoral dogs. In dogs the prevalence for babesiosis was found highest in German shepherd breed, whereas for trypanosomiasis and mixed infection Cross breed was the most susceptible breed. For trypanosomiasis and mixed infection Cross breed was the most susceptible breed type. The prevalence for babesiosis was found highest in the month of September. For trypanosomiasis and mixed infection, the month of October was found to be highest susceptible month for dogs.
Chemotherapeutic trial of topical acaricides against tick infestation in dogs revealed that Fipronil was more efficacious drug as compared to Ivermectin.
Such type of epidemiological data of tick infestation, TBHDs and its chemotherapeutic trial will help to control tick infestation and tick borne hemoparasitic diseases to save the life of companion animal. Availability: Items available for loan: UVAS Library [Call number: 2303-T] (1).

Publisher: 2015Dissertation note: Foal diarrhea is one of the major threats to equine industry that causes high morbidity and mortality. Electrolytes (Na, K, Ca, Fe, Cu and Li etc) and water losses reduced dietary intake and probable translocation between intracellular and extra cellular compartments. Electrolytes are essential for controlling membrane potential, muscle contraction, nerve condition, and enzyme reactions, and they play a central role in the physiological processes. Serum electrolytes and trace elements deficits are the major causes of fluid and acid-base imbalance in diarrheic foals. Keeping in view the importance of foal diarrhea and its impact on the equine industry the current study was designed to determine serum concentration of electrolytes (Ca, K, Na) and trace elements (Li, Cu, Fe) along with the associated risk factors in diarrheic foals.
The present study was designed to examine diarrhea in foals at various equine stud farms, private and public veterinary hospitals. For this purpose a total of (n=100 foals) suffering from clinical diarrhea irrespective of the cause of diarrhea selected randomly after clinical examination and (n=10 foals) negative for diarrhea as control were included. Data of each diarrheic foal was collected separately in a data capture form. Blood and serum sample were collected for hematological and serum biochemical studies, respectively. Concentrations of serum electrolytes (Ca, Na, and K) were analyzed by Flame Photometry and trace elements (Cu, Li, and Fe) were estimated through Atomic Absorption spectrophotometer. PCV was determined by micro hematocrit method. Risk factors including species and age were analyzed for association.
Foals which were suffered from diarrhea showed increase in Pack cell volume. Serum concentration of Sodium, potassium, calcium, iron, copper and lithium were measured in diarrheic foals by atomic absorption and flame photometer method and were compared with healthy group of foals.Foals having diarrhea showed an acid baseimbalance as a result decrease in serum electrolytes and trace elements. The blood acid-base balance is precisely controlled because even a minor deviation from the normal range can severely affect many organs. The body uses different mechanisms to control the blood's acid-base balance.Sodium and potassium and calcium are important electrolytes imbalance in diarrhea. Potassium level was increased in foals having diarrhea. Calcium concentration in ppm significantly decreased from its normal value. In some diarrheic foals increased in level of calcium was also observed because these foals have blood in their feces that result in the calcium to come in blood as a clotting factor. Trace elements such as Cu, Fe and Li are needed in a very little concentration for many physiological functions. The serum iron was measured in foals having diarrhea.The iron concentration was less than normal value.The deficiency of iron lead to anemia. Clinical signs of anemia because of irondeficiency are rarely seen in foals. Therefore, mineral imbalances influence iron metabolism and may cause iron deficiency in foals. The serum copper concentration was significantly decreased in the diarrheic foals. Copper concentration is also related to the packed cell volume as in anemia copper deficiency is a significant feature. Copper is important element and its deficiency lead to decrease in serum concentration of iron. This decreased level might be because most of the circulating copper in plasma is attached to the serum glycoprotein, ceruloplasmin. Ceruloplasmin has ferroxidase activity and may be required to deliver iron into the circulation Therefore it was observed that low iron concentrations might have resulted from copper deficiency.The concentration of Lithium was also decreased in diarrheic foals when compared to healthy foals.

Publisher: 2017Dissertation note: Bovine mastitis is one of the most significant problems of livestock causing huge economic losses in dairy industry of Pakistan. Among other bacterial etiology of bovine mastitis, the Staphylococcus aureus is overwhelming to control and is well-known to cause subclinical and contagious mastitis. Methicillin resistant Staphylococcus aureus is our prevailing field issue. In view of the economic importance of Staphylococcus aureus mastitis, the current project was designed to study the Clinico-epidemiology of multiple drug resistant Staphylococcus aureus in bovine mastitis.
A total number of 900 milk samples (n=450 cattle, n=450 buffalo) were collected from Faisalabad district of Punjab, The collected samples were processed in laboratory of Microbiology and Medicine, Faculty of Veterinary Sciences, University of Veterinary and Animal Sciences, Lahore. Primarily, screening of subclinical mastitis was done by Surf Field Mastitis Test (SFMT). Milk samples were spread out primarily on blood agar to rule out possibility of loss of later growth. Colonies with round and golden color characteristic were put to sub-culturing on Mannitol salt agar as differential and selective medium. The morphological and microscopic clarification was done under microscope using Gram’s staining technique. Various biochemical tests including coagulase and catalase were applied.
Prevalence of subclinical mastitis was found 55% (495/900), however significant differences were found among different tehsils of district Faisalabad. The prevalence of subclinical mastitis in cattle from district Faisalabad was found 54% (243/450) that upon comparison between different cities presented significant difference. While buffaloes presented 56% of subclinical mastitis. Comparisons of subclinical mastitis among different tehsils were

found significant.
Among quarter based prevalence of subclinical mastitis and prevalence of blocked quarters the number of blocked quarters were found 5.58% (201/3600) with highest percentage of blocked quarter noted in case of front right followed by rear right , front left , and rear left with 6.89, 6.56, 4.67, and 4.22%, respectively. However, the quarter based prevalence was found 32% (1088/3399) from bovine. The association of bovine subclinical mastitis with different risk factors presented significant association with few exceptions. Age, parity and body health status of animal were found non- significant with prevalence of mastitis. The breed and open rearing system presented significant relation with chances of mastitis. Chi-square test was used to statistically correlate the risk factors and prevalence of subclinical mastitis. P-value less than 0.05 was considered as significant.
Molecular confirmation of S. aureus was done by using coag gene through PCR technique. The S. aureus which were isolated from milk samples were put to antibiotic (oxacillin) sensitivity test for estimation of prevalence of methicillin resistant S. aureus from the bovine mastitis. Molecular identification of mec-A gene in staphylococcus aureus was done through PCR. The PCR confirmed methicillin resistant S. aureus isolates from cattle (n=20) and buffalo (n=20) were tested for their in-vitro drug response. However, Ciprofloxcin, Moxifloxacine, Linezolid, and Trimethoprim + Sulphamethoxazole were found 100% effective against multiple drug resistant Staphylococcus aureus and Levofloxacin showed 90% efficacy in bovine. While Oxytetracycline, Tylosin, Gentamycin, Amikacin, Vancomycin, and Fusidic acid were also found sensitive moderately except cefoxitin which was responsible for 100% resistane in bovine. Gentamycin was found to much more effective in buffaloes rather than cattle.
Summary
