Publisher: 1992Dissertation note: Due to neglect of proper hygienic measures, the water buffaloes are subjected to many snail-borne parasitic diseases. Amongst these diseases, paramphistomiasis due to bile duct fluke Gigantocotyle explanatum has been reported from many tropical countries including Pakistan. This parasite has been reported to cause various degrees of hepatic dysfunction in the buffaloes.
In the present study, 450 buffaloes were examined for the record of prevalence of explanatum infection. The age dependent prevalence recorded in 3 age groups i.e. upto 2 years, 2-5 years and above 5 years, was 18.2%, 30.5% and 61.4% respectively. Majority of the buffaloes in age groups upto 2 years and 2-5 years were lightly infected (100% and 78.8% respectively). Moderate infection was observed in 2-5 years and above 5 years age groups (2 1.2% and 33.3% respectively). Heavy infection (45%) was only observed in buffaloes above 5 years of age.
The pathological lesions produced by G. explanatum were observed in infected livers from groups A(upto 2 year), B(2-5 years) and C(above 5 years). Grossly, the notable changes in the size, color, consistency and appearance were recorded only in heavily infected buffaloes above 5 years of age (group C). The parasites were mostly seen attached to the common bile duct mucosa. Only in heavily infected buffaloes the parasites were seen attached to intra-hepatic bile ducts mucosa. Lentil sized nodules were observed at the site of attachment of the parasites. The walls of affected bile ducts were thickened and lumina were dilated to accomodate the parasites.
The microscopic lesions included degeneration and desquamation of epithelium of affected bile ducts. The subepithelial mucous glands showed hyperplasia. Mono-nuclear cells infiltration was observed in the subepithelial tissues. Proliferation of fibrous connective tissue was seen on the outermost layer of the affected bile ducts. Disruption of hepatic cords and dilatation of sinusoids were mostly observed in the areas adjacent to affected bile ducts. The portal tracts showed fibro-cellular reaction.
The serum samples from infected groups A, B and C and control groups A1, B1 and C1 were analysed for the study of serum total bilirubin patterns. The serum bilirubin level gradually increased with the increase in degree of parasitic infestation. The serum bilirubin level increased significantly in infected buffaloes above 2 years of age (group B and C) as compared to infected buffaloes below 2 years of age (group A). In the case of buffaloes above 5 years of age (group C), there was a significant increase in serum total bilirubin level in infected group as compared to control group. The major cause of increase in bilirubin level, in this case, was heavy parasitic infestation.

Publisher: 1993Dissertation note: Prevalence of HPS was recorded by surveying 55 broiler farms in and around Lahore between September 1990 to December 1990. Out of these 55 broiler farms 12 farms were affected with HPS. From 12 affected farms 15225 birds died due to HPS, so the average mortality recorded was 16.36 percent. Indicence of HPS recorded was maximum between 3rd to 5th to week of age, however birds of younger & older age groups were also affected with HPS. Different breeds & feeds have no affect on prevalence of HPS. HPS inoculum prepared from morbid livers, when inoculated into 10 days old, twenty embryonating eggs with 0.2 ml through chorioallantoic membrane route, caused 100% mortality within 3-6 days post inoculation.
Day old, 120 broiler chicks were reared and divided into four groups A, B, C, D each comparising of 30 chicks. At the age of 21 days, broiler chicks of A, B and C groups were inoculated against HPS through various routes i.e. oral, subcutaneously and Intramuscularly, respectively, while D group remained control. Mortality was recorded for the experimental period of 12 days. It was noted that the broiler chicks in group A, 3 birds died having 10% mortality, in group B, 17 birds died having 56.66% mortality while in group C, 14 birds died having 46.66% mortality.
Mortality was maximum within first 5 days, whereas mortality become minimum in the last 4 days of the experimental period. Common clinical signs observed were sudden increase in mortality, depression, yellowish diarrhoea, huddling of the birds.
The histopathological changes in affected broiler chicks included ballooning of the pericardial sac with blood stained (amber) fluid. The pericardial fluid varied from 0.5 to 2.5 ml. The heart become flabby, rnisshaped and enlarged. Microscopically, cardiac muscles showed degeneration, mild congestion, leukocytic infiltration. Liver appeared swollen, enlarged, friable, dark brown in colour and show mottling. Pin point subscapular haemorrhagic lesions observed in markedly fatty livers. Microscopically, liver showed fatty changes, massive necrosis, dilatation of sinoids, nuclei become larger than normal. Light basophilic intranuclear inclusion bodies of different sizes observed in liver parenchymoal cells. The kidneys become swollen, enlarged, friable and dark brown to pale yellow in colour. Microscopically, kidneys showed tubular dilatation, degeneration and necrosis. The glomeruli were misshaped and showed glomerunephritis. The thymus did not exhibit any gross or histopathological changes.

Publisher: 1997Dissertation note: This project was designed to study the haematological values and the serum electrolytes (sodium, potassium and chloride) levels in the dogs exhibiting diarrhoeal signs. For this purpose one hundred dogs showing diarrhoeal signs were selected from Dog Hospital, College of Veterinary Sciences, Lahore while ten healthy dogs were also used as control group. Tentative diagnosis was tried to establish in each animal of experimental group. Blood samples were collected from the all the animals of both groups. The aematological parameters (TEC, PCV, ESR and Hb) and serum biochemical analysis (sodium, potassium and chloride) were conducted on all blood samples. The changes in blood values of each case was tried to correlate with its tentative diagnosis.
On the basis of tentative diagnosis conditions observed were: parvovirus infection, parasitic infestation, mixed infection, canine distemper and dietary disturbances. These conditions of experimental dogs were named as groups A, B, C, D and E. Haematological values (TEC, PCV, ESR and Hb) in group A were decreased considerably as compared to the control group. In group B the values of (TEC, PCV and ESR) were decreased while the values of Hb was normal as compared to the control group. Group C also showed considerable decrease in the values of haematological parameters. In group D the change in haematological parameters showed that the values of TEC, Hb and PCV were decreased considerably while the value of ESR was increased considerably. The haematological changes in group E were similar to the changes recorded in group E. The changes in biochemical substances revealed that in groups A, B, C and D the mean values of biochemical substances (sodium, potassium and chloride) were decreased as compared to the control group, in group E values of sodium and chloride were decreased slightly while the value of potassium was within the normal range. All the dogs of experimental groups exhibited macrocytic normochromic anaemia.

Publisher: 1997Dissertation note: This project was designed to determine the immune response, macroscopic and microscopic changes in the Harderian gland (HG) and respiratory organs of young chickens reared in well controlled environment following eye-drop vaccination against ND and subsequent challenge with a NDV field strain. This endeavour also represents an effort to raise the curtain on the extent of local and humoral immunity in response to eye-drop vaccination against NDV and also after challenge by two different routes (intraocular and intratracheal).For this project a total of 150 day old broiler chicks were procured from local commercial hatchery. At day one 6 birds were used to determine the maternal antibody titres against ND. On day 7, chicks were randomly subdivided into 6 subgroups Al and A2, Bi and B2, Cl and C2, each subgroup having 24 birds. Three subgroups were vaccinated through eye-dropping against NDV (i.e. Al, A2 and Cl) at 7th and 21st day of age. The other three sub-groups were kept non-vaccinated (i.e. Bi, B2 and C2). Challenge of virulent NDV was administered at 28t1i day of age by two different routes to the different subgroups. Intraocular challenge was given to Al and Bi subgroups and intratracheal challenge was given to A2 and B2 subgroups, whereas Cl and C2 subgroups were kept as control. Determination of antibody response against NDV by heamagglutination inhibition test and gross and histopathology of Harderian glands, trachea and lungs of six birds of all experimental and control subgroups were performed on days 14, 28, 31 and 35 of age. Ocular vaccination engendered higher level of circulating antibodies against NDV but developed poor local protective immunity in tracheal rrucosa. Intratracheal challenge, caused pronounced changes in vaccinateçl birds by eye-dropping in comparison to intraocular challenge, so it can be infered that route of challenge of NDV played a characteristic' role in developing disease to the host vaccinated through eye-droppings.
