Publisher: 2011 Dissertation note: Hydatidosis is a world-wide zoonotic parasitic disease which is caused by the larval stage of tape worm Echinococcus granulosus and E. multilocularis. It is highly endemic in some regions of the world. Keeping in view the importance of the disease, the present study was conducted to record the age, sex, species and season wise prevalence of hydatidosis in small ruminants. The study also includes comparison of the two serological tests used for the diagnosis of this disease and efficacy of mebendazole was aIso evaluated. Prevalence and organ specificity of hydatidosis was studied in 2400 sheep and 2400 goats of different age and sexes. The overall prevalence of hydatidosis in sheep and goats was 8.25 and 6.21 percent respectively. Sex wise prevalence indicated that it was 9.85 and 7.85 percent in female and male sheep respectively whereas in female and male goats it was 5.83 and 7.23 percent respectively. A reasonably higher prevalence of hydatidosis was observed in female animals as compared with males. In adult animals hydatid cysts were present in 11.38 and 7.77 percent in sheep and goatsrespectively while in lambs and kids it was 1.79 and 1.06 percent respectively. Statistically no significant difference was observed in any season through out the year in both the species. In the present study, lungs were found to be most commonly infected organ in sheep andliver in goats. Out of 198 infected sheep, 45.45 percent had cysts in lungs, 33.84 percentin liver, 10.10 percent in both liver and lungs, 2.53 percent in spleen, 2.02 percent in heart and 6.06 percent in abdomen and thoracic cavity whereas in goats organs specificity was 34.23, 40.27, 16.78, 0.67, 8.05 percent respectively for lungs, liver, lungs & liver both, spleen and abdomen and thoracic cavity. A total of 60 cysts in sheep were examined for fertility and it was found that out of 18 cysts of less than two centimeter size, maximum (50 percent) were suppurative orcalcified and minimum (16.7 percent) were fertile in nature. Of 30 cysts of 2-4 em size,
40 percent were suppurative and 40 percent were fertile and from 12 cysts of more than
four centimeter size, maximum (66.7 percent) were fertile and only 16.7 percent were
sterile in nature. In goats, of 15 cysts of less than 2cm size, maximum (46. 7percent) were
suppurative, and minimum (13.3 percent) were fertile. Of 7 cysts, belonging to the group
of more than four centimeter seize, 71.4 percent were fertile in nature and only 14.3
percent were sterile. Overall fertility rate in sheep and goats was 38.33 and 36.96 percent
respectively whereas overall sterility rate was 23.3 and 32.60 percent in sheep and goats
In sheep, total number of protoscolices found in 23 cysts was 936 of which 72.65 percent
were fertile in nature. The mean of total proto scolices was 40.70 with standard deviation
of 23.05 whereas the mean number of viable protoscolices was 29.57 percent with a
standard deviation of 18.92. In goats, total number of protoscolices observed in 17 cysts
was 719 whereas only 52.71 percent were fertile in nature. The mean of total
protoscolices was 42.30 with a standard deviation of 17.13 whereas mean of viable
protoscolices was 22.30 with standard deviation of 17.10.
Blood samples of 40 positive and 40 negative sheep for hydatid disease were collected
from slaughter house and serum was separated. ELISA and IHA test were applied on
these samples. The sensitivity, specificity, efficacy, positive predictive value and negative
predictive value of ELISA were 92.5 percent each whereas these values for IHA were 80
percent, 97.5 percent, 88.75 percent, 96.96 percent and 82.98 percent respectively. In
goats, blood samples from 40 positive and 40 negative cases of hydatidosis were
collected from slaughter house before slaughtering and ELISA and IHA were applied on
all of these samples. The sensitivity and specificity of ELISA was 90 percent and 95
percent respectively whereas the sensitivity and specificity of IHA was 75 percent and
97.5 percent respectively.
A total of 12 i.e. 6 sheep and 6 goats (healthy) were purchased and kept at Ravi campus
Pattoki, University of Veterinary and Animal Sciences, Lahore. These were divided into
experimental (4 sheep and 4 goats) and control group (two sheep and two goats). In
experimental group, 100 eggs of Echinococcus granulosus were given orally to all
animals and then mebendazole was given to two sheep and two goats on zero day and
then after two months intervals. Blood samples were collected from all animals on zero
day, 90 days and 180th day and serum was separated. ELISA and IHA were applied to all
samples. Mebendazole was not found completely effective and ELISA detected the
infection earlier than IHA. On postmortem examination, multiple cysts were found in all
animals of group A and no cyst was found in group B.
Eighty blood samples of humans i.e. 40 positive and 40 negative for hydatidosis were
coilected, serum was separated and ELISA and IHA test were applied to all the samples.
The sensitivity and specificity of ELISA was 95 percent and 97.5 percent respectively
whereas the sensitivity and specificity of IHA was 82.5 percent and 97.5 percent
The present study will be helpful in disseminating the informations regarding the
prevalence, zoonotic importance, effect of mebendazole in animals and the use of
immunodiagnostic tests for the diagnosis of hydatidosis in small ruminants and human

Serofpidemiology, Zoonotic Potential And Chemotherapy Of Neosporosis In Dogs And Cattle
Material type: Book ; Format:
; Literary form:
Publisher: 2010 Dissertation note: The aim of current study was to demonstrate the most important features of Neospora caninum infection in Pakistan. In the present study, I examined the prevalence of N. caninum in 7 districts of the country and to accessed the efficacy of various drugs against the parasite in cell culture.
For the achievement of this purpose, the core objectives were,
To have an overview on the overall seroprevalence of neosporosis throughout the country by means of cELISA in aborting, at risk and clinically healthy cows.
To check the correlation of Iscom ELISA and cELISA, and determination of prevalence of N. caninum by means of Iscom ELISA on milk samples.
To identify the transmission of disease towards human.
To determine the efficacy of various drugs against N. caninum.
In phase 1, overall seroprevalence of N. caninum in dairy cattle (detected by means of cELISA, VMRD, Inc., Pullman, WA, USA) was found to be 43.4% with a significant difference (P < 0.05) of seropositivity among all 18 herds (n = 5 aborting herds, n = 13 non-aborting/clinically healthy herds) selected from 7 districts of Pakistan. The seropositivity of cattle to N. caninum antibodies was significantly higher in aborting animals (52.7%) as compared to non-aborting cows ( 41.5%), indicating a significant difference between aborting and non-aborting cattle. In case of pregnant and non-pregnant animals, similar findings were recorded in our study. A significantly higher rate of seroprevalence was observed in pregnant dams (59.8%) than non-pregnant cattle (35.2%). Overall, higher serological prevalence was evaluated during the summer season (61.1%) in all areas followed by autumn (46.9%), spring (34.9%) and least seropositivity was observed in winter season (26.6%).
The difference in seropositivity was significantly different among all age groups, greater in animals older than 2 years of age. Furthermore, the prevalence was statistically significant (P < 0.05) among cattle of different breeds. Seroprevalence in cases of crossbred animals were higher followed by exotic and indigenous breeds.
Phase 2, describes the seroprevalence of N. caninum in clinically healthy dairy cows. A selection of 760 animals from 13 dairy herds located in Punjab and Sindh Province, Pakistan to demonstrate the presence or absence of the Neospora caninum infection in commercial dairy cattle. The serostatus of the cows towards N. caninum was detected by cELISA (VMRD, Pullman, WA). Out of 760 animals, (43.2%) were seropositive to N. caninum. A significant difference of positivity was recorded among all 13 dairy herds. Age wise prevalence though not statistically significant among all age groups, was greater in animals over 2 years of age and least in heifers. Variation was also observed in samples from cattle of different breeds. A significantly higher prevalence was observed in crossbred animals than in purebred and nondescript cattle. Seasonal prevalence was higher during summer season than rest of the seasons. The seroprevalence of N. caninum in pregnant cows was significantly greater than in non-pregnant animals.
Second experiment of this phase describes the seroprevalence of 240 animals from 5 herds with a high rate of abortion, the percentage of seropositivity observed in these herds was 43.8%, slightly higher than the clinically healthy and non-aborting cattle. No significant difference was observed among all sample locations in this experiment. However, significant difference of positivity was recorded among different breeds of cattle. Age wise prevalence, though not statistically significant (P > 0.05), was greater in animals older than 2 years of age.
The assessment of milk samples from lactating cows were also determined for Neospora caninum antibodies by means of Iscom ELISA (SANOVIR® Sanova Biotech AB, Uppasala, Sweden) and showed a good level of agreement (r² = 0.9959) between the two tests (cELISA and Iscom ELISA). Although, the cELISA (VMRD, Inc., Pullman, USA) expressed a higher seropositivity and sensitivity than Iscom ELISA (Sanova Biotech AB, Uppasala, Sweden). Therefore, both of the ELISA tests (cELISA and Iscom ELISA) for the detection of N. caninum antibodies in dairy cattle can perform better in lactating animals. The Iscom ELISA has some advantages over cELISA as it's easy to collect milk samples than serum samples, moreover Iscom ELISA is cheaper and easy to use but has low sensitivity than cELISA and cannot be used in dry animals. The percentage of positivity detected through Iscom ELISA on individual milk samples were 61.4% and 76.6% by cELISA.
In phase 3, an epidemiological study was conducted to determine seroprevalence of N. caninum in dogs of different breeds and age groups. The serum samples of dogs were analyzed by cELISA (VMRD, Pullman, USA) showed a seropositivity of 23.5%. There was no significant difference of seropositivity among various sample locations, highest prevalence was observed in Muzaffar Garh (31.9%), followed by Gujranwala (27.9%), Lahore (25.1%), Hafizabad (20.2%) and least prevalence was recorded in district Okara (14.6%). A significant difference in prevalence of N. caninum antibodies between male (26.1%) and female (18.8%) dogs were recorded. The difference in seroprevalence was not significant among all age groups. The samples with no age record showed a highest prevalence (29.5%) and least seropositivity was observed in adult dogs of 3-6 years of age (18.7%). During Summer season, highest positivity to N. caninum was (31.0%) recorded while the lowest prevalence (16.0%) was observed in Winter season.
Phase 4, describes the seroprevalence and transmission of N. caninum in humans. A selection of 52 serum samples from humans was analyzed for the presence of N. caninum antibodies. The serostatus of the humans towards N. caninum antibodies (IgG) was determined by using commercially available antigen coated IFAT slides (VMRD, Inc., Pullman, Washington USA) and human conjugate. Overall very low prevalence (1.9%) of N. caninum antibodies was reported in this study. Only one case was found to be positive, these findings indicate that no strong evidence of N. caninum infection in humans.
In phase 5, in vitro drug trials was conducted to access the best efficacy of three commercially available drugs. We found that among three anticoccidial drugs i.e Clindamycin, Diclazuril and Sulfadiazine, Diclazuril has best inhibitory effect against N. caninum tachyzoites in cell culture followed by Clindamycin and sulfadiazine.

Epidemiology, Zoonotic Potential, Serodiagnosis And Chemotherapy Of Sheep Fasciolosis In Different Ecological zones of balochistan
Material type: Book ; Format:
; Nature of contents: ; Literary form: Publisher: 2012 Dissertation note: Various epidemiological aspects of human and sheep fasciolosis were investigated in four districts of Balochistan (Pakistan) having different ecology i.e. district Bolan from (Plain zone), Lasbela (Coastal zone), Qilla Saifullah (sub humid and semi arid sub zone of Upland zone) and district Pishin from (Arid sub zone of Upland zone). Sheep samples were examined through Coprological examination showed overall prevalence of 10.26% in one year study period from June 2010 t0 May 2011. The uppermost prevalence was recorded in district Bolan (14.79%) followed by Lasbela (10.63%), Qilla Saifullah (8.75%), and the lowest in district Pishin (6.88%). Overall the highest prevalence by season was recorded in autumn (25.31%) followed by winter (9.22%), summer (6.41%) and lowest in spring (5%). Amongst the month the overall highest prevalence was recorded in the month of September (30.63%) and lowest in the month of May (1.88%). Sex wise prevalence was found highest in female more susceptible to infection (11.22%) than male (8.48), but sex wise difference was non-significant statistically. Amongst the age group significantly higher prevalence was recorded in adults young than adult of age group (5.91%).
During one year study period prevalence (%) of human fasciolosis in some districts of Balochistan was recorded (0.42%), with overall district wise prevalence in Qilla Saifullah and Bolan (0.83%) and (0%) in Lasbela and Pishin. Overall season wise prevalence was noted the highest in autumn (1.25%) followed by summer (0.63%) and 0% prevalence in winter and spring. Month wise results showed 2.5% prevalence only in the month of August and October while 0% in the other months. Gender wise prevalence 0.42% was
found only in male, no female samples were collected due to some religious, traditional and community problems. Prevalence by age was recorded the highest in above 20 years of age group (0.74%) while this value decreased to zero in below 20 years of age group.
Antibodies against fasciolosis in serum samples through indirect (ELISA) were recorded 13.13% (63/480) in sheep and 0.42% (2/480) in human indicates the higher prevalence (%) as compared to fecal examination. Likewise district, age and sex wise seroprevalence (%) of fasciolosis was reported higher than coprological examination in case of humans as well as in sheep.
In sheep positive correlation was noted between fasciolosis and relative humidity while negative correlation with temperature (ºC) and rainfall (mm). While in humans prevalence positive correlation was observed with temperature (ºC), relative humidity (%) and rainfall (mm).
Overall 1123 snails belonging to different 5 genera were collected from different district from different agr-ecological zones of Balochistan from June 2010 to May 2011. Amongst the snails the highest prevalence (37.04%) was found for Indoplanorbis, followed by Bulinus (32.15%), then Lymnea (20.66%), Melanoides (5.52%) and the lowest Physa (4.63%).
Comparative study for coprological and serological tests (ELISA) was conducted for four districts from different agro-ecological zones of Balochistan i.e. District Bolan from (Plain zone), Lasbela (Coastal zone), Qilla Saifullah (sub humid and semi arid sub zone of Upland zone) and district Pishin from (Arid sub zone of Upland zone) for one year i.e. from June 2010 t0 May 2011. Overall prevalence of sheep and humans was 0% and 8.13% by coprological examination and 13.13% and 0.42% by indirect ELISA tests. Prevalence by ELISA was found higher than fecal examination when analyzed statistically. Similar seroprevalence for month, districts, age and sex was noted higher than coprological examination for sheep and humans. ELISA Sensitivity (%) and specificity (%) was recorded >97.0% and 95% and 100%, 100%, respectively for sheep and humans.
Indigenous plants i.e., Saussurea lappa (roots), Fumaria parviflora (aerial) and Caesalpinia crista (seeds) were used at dose level of 60, 70 and 80 mg/kg body weight against naturally infected sheep with fasciolosis and their effectiveness was compared with triclabendazole (10mg/kg body weight). Triclabendazole was found 100 % effective after second dose whereas all herbal medicine it reached up to this mark after administration of second dose of 80 mg/kg body weight. From this study we can conclude that these herbal medicines can safely replace the triclabendazole, which is not, only cost effective but have no side effects.

Publisher: 2012 Dissertation 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.

Epidemiology Zoonotic Potential Haematology Amd Chemotherapy Of Sarcoptic Mange In Camel In Punjab
Material type: Book ; Format:
; Literary form:
Publisher: 2015 Dissertation note: A camel is a very hardy ruminant animal, which can survive under harsh climatic
conditions very effectively by utilizing the marginal areas with excellent capabilities and produce
under such conditions (Hjort and Hussein, 1986; Abbas and Tilley, 1990). Camel is an important
animal as it is well adopted in unique manners in the hot, arid and semi-arid environments
(Schwartz, 1992). It can survive without water and food for many days and this unique ability of
camel makes it an ideal for such harsh conditions for which it is also commonly known as “The
Desert Ship”. In spite of the fact that camel is an important member of a group of animals which
produces food for human consumption in the shape of milk and meat, yet it is the most neglected
one in the field of scientific research. It may be due to the fact that camel belongs to such areas
of the world which are arid, semi-arid or rain fed in nature, having harsh climatic conditions,
where poor nutrition and poor management are the major issues (Sohail, 1983).
It is an established fact that diseases originating from parasites lead to the main health
hazard issues in animals. These parasites survive at the expense of the host animals causing lot of
health problems, like skin irritation, anemia leading to weakness and debility. Some of the
parasites have zoonotic importance and may become a source for the transfer of many contagious
diseases like scabies to the human beings (Dominguez et al. 1978). McClain et al. 2009,
observed the scabies as a major health problem globally both for humans and animal population.
Sarcoptes scabiei is an ectoparasite which is a cause of scabies, a skin problem in the human
beings worldwide and the similar species of mites do also produce a similar type of disease in a
large variety of wild and domesticated mammals (Pence and Ueckermann, 2002; Fitzgerald et
al. 2004). Fain, 1978, reported that more than fifteen (15) different species of Sarcoptes scabiei
morphologically and genetically distinct from each other have been identified in different hosts.
Sarcoptic mange is the second important problematic disease of camel after
Trypanosomiasis (Nayel and Abu-Samra, 1986). Scabies caused by Sarcoptes scabiei var cameli
is a serious & highly contagious skin problem and also economically important disease of the
camels (Pegram and Higgins, 1992). Camels, which are reared with deficient nutrition, poor
management and under unhygienic conditions are mostly affected by this disease (Kumar et al.
A large group of people and communities living in arid diverse ecozones in the entire
world, particularly in harsh climates earns their livelihoods by depending on camels. This
dependence may spread to the utilization of camel milk, meat, wool and leather besides its use in
transportation, riding and sports (Wilson, 1984; Snow et al. 1992). In Pakistan camels are also
raised by the people for meat, milk, riding, transportation and sports purposes in the deserts, semi
desert & rain-fed / warm areas of the entire country being a hardy animal as it can tolerate easily
the rugged climate as well as extremes of temperatures of such areas.
The natural harsh and adverse climatic conditions, particularly during long dry seasons
lead to a paucity of feeding regimes resultantly the camels raised in such areas are subjected to
stress conditions which lower their resistance and make them easily vulnerable to diseases
(Abbas et al. 1993; Agab, 1993). Abbas & Tilley, 1990; Saint-Martin et al. 1992; Abbas and
Agab, 2002; Pathak and Chhabra, 2010; while reviewing the parasites & parasitic diseases of
camel population in India were of the opinion that Sarcoptic mange is a serious, debilitating,
dreaded and widely prevalent disease of camels in India.
Besides other infectious diseases of bacterial and viral origin, camels are exposed to a
wide range of internal & external parasitic infestations. Amongst other so many external
parasites to which camels are exposed, the Sarcoptic mange is recognized to be one of the most
serious and damaging disease. This disease is caused by a mite known as Sarcoptes scabiei var
cameli which belongs to genus Camelus of SARCOPTIDAE family in Veterinary Entomology.
It is an extremely pruritic, contagious and debilitating skin disease which is very
frequently and sudden in onset. It is also ranked as one of the most serious and important disease
of the camels. Sarcoptic mange infestation is very common in the areas of thin skin, the head,
neck, flanks, medial aspect of thighs or inguinal region, mammary glands and prepuce. The head
is usually affected very rapidly as the animal uses its teeth for scratching the affected areas.
Besides linking the occurrence of the disease with poor camel management, malnutrition and
contact with infected objects, the stray & infected camels also often become a focus of infecting
the healthy animals when mingling with them particularly at watering places for drinking
purpose (Richard, 1987; Abdel-Rehman et al. 2001).
Sarcoptes is a burrowing mite as it penetrates deeply through the skin surface of the
infected camel. This burrowing of mites in the skin helps these parasites lead to intense pruritus
and exudative dermatitis. In pruritus, mites penetrate deep into muscular areas, damaging the
flesh and lowering the quality of meat. The early inflammatory reaction of the host body towards
the mites becomes evident in the shape of small popular elevations, invasion and injuries leading
to formation of hairless areas, scaly crust formation or scabs on the affected parts and the skin
become dark and thickened. Skin of mangy camel show hemorrhages, and subcutaneous odema
after the development of fissures in the underlying epidermis (Kumar et al. 1992; Amer et al.
The fertilized female mites create winding burrows or tunnels in the upper layers of the
epidermis of the skin of the host animal and feeding on the serous exudate, a liquid oozing from
the damaged tissues. The female mites lay about 40-50 fertilized eggs in these tunnels which
hatch in 3-5 days into a six legged larvae. These larvae immediately crawl to the surface and
burrow themselves in the superficial layers of the skin and create small molting pockets. In these
molting pockets, the larvae molt to next stages of nymph and adult. The adult male then emerges
and seeks a female either in the molting pocket or on the surface of skin. After fertilization the
female produces new tunnels, either de novo or, by extension, of the molting pockets, lays eggs
in these tunnels and a new life cycle starts. The entire life cycle of Sarcoptic mange is completed
in 17-21 days.
New hosts can be infected through direct transmission by contact between the animals,
presumably from larvae, nymph or adult mites, which are commonly present on the skin surface
of the infected animal. Indirect transmission of infestation can also take place through the objects
or fomites having mange infection, which come into contact with the affected camel, such as
harnesses, blankets, baggage tack, tents and tree trunks (Richards, 1987). The pruritus increases
as the mites penetrate deeper in the skin (Al-Rawashdeh et al. 2000, Driot et al. 2011, Bekele et
al. 2012). Based on the rate of infection camels can be seriously disturbed by the Sarcoptic
infestation as they may stop grazing which can lead to a rapid fall in milk production, and
deterioration of health condition. With the increase in the irritation due to scabies, the camel
rubs, bites and scratches the affected areas in an attempt to reduce the itchiness. Due to rubbing,
biting or scratching, the mites move to the periphery affecting the healthy tissues and resultantly
affected area spreads. As the disease prolongs, the skin becomes excoriated, leading to hair loss
and the development of scabs. These scabs in turn may be rubbed away and a red surface
developed. The animal becomes restless due to severe Sarcoptic mange infestation and
involvement of most of the body surface. If the diseased animal is not treated in time, the animal
loses its health condition, become emaciated and within two, three weeks the acute stage of
disease may give way to more chronic state (Gorakh et al. 2000, Abubakar et al. 2002, Driot et
al. 2011). Sarcoptic mites rarely survive long off the host under natural conditions.
A continuous direct contact of animal keepers with their camels can also lead to
transmission of diseased condition in human beings which is termed as pseudo scabies.
Transmission of infection from camel to man usually takes place during milking, handling or
riding. The main symptoms of pseudo scabies can therefore be seen in the inter digital spaces of
the hands, on the wrists, forearms, the elbows, the axillary folds and inner side of the thighs.
Once a herd is infected with Sarcoptic mange, continuous reinfection of the disease occurs
(Schillinger 1987, Singh & Veer 2005, Premalatha et al. 2010).
Sarcoptic mange is usually considered to be a seasonal disease and is often reported
severe during the winter months as in cold weather the disease had an acute course. However,
there is some evidence that in some countries hot weather predisposes to acute outbreaks of
camel mange and in the cooler, winter season the rate of mange infestations are at the lowest. In
the summer the activity of the mite seems to decline or disease becomes chronic. Dietary intake
is an important factor in mange infestation. Nomadic camels on a low nutrition plan, probably
carrying heavy worm burdens in hot desert conditions are likely, therefore, to be highly prone to
Sarcoptes at this time (Dinka et al, 2010). During such periods of great activity, the mites are
readily transmissible from one animal to other animals (Richards, 1987, Banaja & Ghandour,
1994, Tefera & Gebreah, 2001).
Mange can easily be diagnosed clinically from the occurrence of pruritus, depilation,
alopecia, thickened skin, folds around the joints and encrusted plaques being the main
characteristics of this parasitosis. In order to control this zoonotic disease, it is essential to treat
both camel and man along with effective checks over other predisposing factors of the disease
such as hygiene and nutritional requirements of the animals.
The skin diseases like the scabies both in human beings and animals are being treated
with a variety of allopathic drugs now a day, but the role of herbal plants in use since centuries in
different shapes cannot be ignored at all, especially in the rural lifestyle. Further with the
continuous use of different acaricidal drugs, the issue of resistance development has come across
as a challenge for the researchers to find some alternatives for the purpose. Accordingly the
research work on the use of traditional herbal medicines is gaining attention day by day.
Although there are many reports and studies regarding the prevalence of Sarcoptic mange
in camel from different parts of the world, only few preliminary reports are available for Pakistan
and none of them provide detailed epidemiology of Sarcoptic mange and its effect on host
health. Therefore, keeping in view the importance of the mange problem in camel population of
the country, the present project was designed to determine the prevalence of Sarcoptic mange
infestation, factors in its occurrence its zoonotic importance, effect on blood physiology and
different treatment options in the camel population of Punjab, province in Pakistan.

Clinico-Epidemiological And Experimental Observations On Feline Lower Urinary Tract Disease Among Domesticated Cats
Material type: Book ; Literary form:
Publisher: 2015 Dissertation note: Idiopathic Feline Lower Urinary Tract Disease (iFLUTD) has been known as a major as well as important problem throughout the world especially the veterinary profession. Nicks of this problem also found in Pakistan, however the veterinarians are usually unable to properly diagnose this disease due to lack of knowledge as well as the ancillary diagnostic equipment availability for this disease. Present study was divided into two phases. Phase – 1 included clinico-epidemiological data. To this end, target of more than 502 domesticated client-owned cats of either sex, age, breed, etc showing signs of feline lower urinary tract disease (FLUTD) as per Buffington (1994) were examined accordingly from 3 different cities (Lahore, Faisalabad, and Islamabad) of Pakistan). All data collected was based on a predesigned proforma by using structured interview of the owners. Diagnosis was solely based on serum-cortisol levels, urinalysis, radiography and ultrasonography. Phase II involved experimental trial. The data obtained from whole of the study was then presented in tabulated form as frequencies and percentages. Treatment and outcome of the disease were also analyzed accordingly.
According to the present study conducted it is proved that iFLUTD is present among the cats in Pakistan. Its proper cognizance among the Pakistani veterinarians is still non-existent and is misdiagnosed as colic or constipation issues in cats. The present study was undertaken to bring iFLUTD into the reportive of small animal practitioners working in Pakistan. The present study debunked various previous notions like iFLUTD is associated with commercial diets and canned foods only if we talk about this region majority of cases were noticed that had home-cooked food given by the owner. Moreover, cases in Siamese breed are larger than Persian breed. It has been strongly associated with Indoor housing management. Additional work is still needed to explore untouched areas of epidemiology including factors other than those being studied in the previous literature. Academicians in veterinary pathology and veterinary medicine of Pakistani universities should embrace this malady in the Doctor of Veterinary Medicine (DVM) curricula.
According to the present study results it is concluded that two factors like stress and pain accelerate the sympathetic nervous system outflow compared to normal felines leading to the inflammatory response. Thus the stress factor must be reduced in the form of making hiding places for cats at home to reduced down the fear factor along with enhancing the feeling of owes for that particular place. Moreover, some more practices should be performed by the owner to reduce down the stress factor like playing with the pet, giving full attention, placing toys and other attractive things like yarn balls at the feline places (where they live/placed). There was no significant difference found between the groups based on the food with health score along with the therapeutic judgment. Hence, it is recommended that more experiments should be performed on larger scale to assess GAG therapy on increased number of felines and need of hour is to conduct more veterinary studies to get information and authenticity for its use against iFLUTD.
From this study conducted, I recommend to the owners that the cats must be provided with the indoor hiding places and play with their pets in order to reduce the stress factor that increases the risk of idiopathic lower urinary tract disease. Moreover, the trend of home-cooked diet should be reduced along with increase in water intake by the cat.
