Publisher: 1990Dissertation note: The study was conducted to determine the prevalence of Paramphistomes in sheep, taxonomy of the species of the genus Paramphistomum, and their effects on various blood parameters of the infected animals. For this purpose Municipal Corporation Abattoir, Peshawar was visited regularly during the months of May, June and July,1990. A total of 300 sheep were examined for the study purpose. These animals were divided into two age groups each comprising of 150 sheep. Group-I comprised of sheep below one year of age, while Group-II had sheep of more than one year age. Fifty sheep, each from Group-I and Group-II, were examined each month during the course of study.
Five ml of blood was collected from the jugular vein of the sheep, prior to slaughter, in a test tube having a few drops of 0.1% EDTA. After its slaughter the compound stomach of the animal was obtained and put into a polythene bag, which was then brought to parasitology Section, Veterinary Research Institute, Peshawar for further investigations. After opening of the compound stomach, each compartment was searched for paramphistomes. Helminths so collected were put into glass jars. Preservation and staining of Paramphistomes was carried out by adopting the prescribed methods. Complete record of worms collected, regarding their number and site of predilection was maintained. The taxonomy of the species of the genus Paramphistomum was studied with the help of keys.
All the parasites of the genus Paramphistomum were recovered from the rumen of the infected sheep identified as Paramphistomum cervi.
A total of 2,329 helminths (Paramphistomum cervi) were recovered from infected sheep of both the age groups.Average infection rate in these animals was recorded as 7.00%, with an average worm burden of 111 helminths per animal.
Out of 150 below one year of age sheep examined, 8 were found infected with Paramphistomum cervi with an infection rate of 5.33%. Three sheep from Group-I were found infected with Paramphistomum Cervi in each of the month of May and June, while in July only two animals were found infected with these parasites. The highest rate of infection with these parasites was observed in May and June, and the lowest infection rate was recorded in the month of July. A total of 727 helminths were recovered from the infected animals of Group-I with a range of 73 to 112, and the average parasitic load being 91 per animal.
150 sheep of above one year age were examined,out of which 13 were found infected with Paramphistomum cervi, with an infection rate of 8.66%. Six animals of Group-II were found infected in May, for in June and three in the month of July. A total of 1,602 parasites were recovered from these animals, ranging from 96 to 140, with an average worm burden of 123 helminths per animal.
Blood of infected sheep was exposed to various haematological studies including total erythrocyte count (TEC), Hb estimation, packed cell volume (PCV) and erythrocyte sedimentation rate (ESR).These tests were also carried out for worm-free (control) sheep, 10 each from Group-I and Group-II.
A decrease of 8.39% and 14.20% was noticed in total erythrocyte count (TEC) of the infected sheep of Group-I and Group-II, respectively. The results revealed that a highly significant decrease in the TEC of these animals had occurred due to Paramphistomum cervi infection.
Haemoglobin contents of blood were determined. The results showed a fall in the Hb contents of blood. The results of the study revealed that a non-significant decrease resulted due to paramphistomiasis in the Hb contents of blood of animals with below one year age, while a highly significant decrease occurred in the haemoglobin contents of blood of animals with above year of age.
A decrease of 3.35% and 12.25% was recorded in the packed cell volume (PCV) of the infected sheep of Group-I and Group-II, respectively. The results showed that a non-significant decrease occurred in the PCV of infected animals of Group-I, while a highly significant decrease was caused by paramphistomiasis in Group-II animals.
The erythrocyte sedimentation rate (ESR) of worm free (control) as well as sheep infected with Paramphistomum cervi was determined. The results showed a 14.0% and 141.42% increase in the ESR after one hour in the infected animals of Group-I and Group-II, Respectively, while the increase in ESR after 24 hours was recorded as 120.5% and 196% for these groups, respectively. The results revealed that a significant increase occurred in ESR of infected sheep of Group-I, after one hour as well as 24 hours, a highly significant increase was observed.
Statistical analysis of the results of the study also revealed that there existed a negative correlation between age of the animal and total erythrocyte count, haemoglobin concentration, and packed cell volume of blood. A positive correlation existed between age of animals and erythrocyte sedimentation rate.

Publisher: 1991Dissertation note: The present project was designed to estimate and compare the extent of helminth infestation in Desi (indigenous) and commercial (W.L.H) poultry layers along with taxonomi study of the isolated species.
A total number of six hundred (600) gut samples of adult layers i.e. three hundred (300) each of desi (indigenous) and commercial (W.L.H) were collected from June through october 1991. The parasites were recovered from the gastrointestinal tract of birds by adopting described method at the Parasitology Laboratory College of Veterinary Sciences Lahore.
The overall prevalence of helminth parasites (netnatodes and cestodes) was 80.3% in desi and 32.6% in commercial (W.L.H) birds.
The nematodes were found in 210(70%) in desi (indigenous) and in 62 (20.6%) of commercial (W.L.H) guts. Among the nematodes different species were identified and their infection rate on single and/or multiple basis was established. Ascaridia galli was the most prevailing species 167 (55.6%) followed by Heterakis allinae 38(12.6%), Subulura bruinpti 45 (1b.k) wniie iiojua trachea was very rare and was present only in 5 (1.6%) of desi (indigenous) birds.
In commercial (W.L.H) layers the nematodes singly and/or on multiple basis were recorded in 98(32.61) of birds Ascaridia alli alone infected 49(16.3%), HtrJd. gallinae 7 (2.3%) and Subulura brunipti 8 (2.6%) of birds while Svnainus trachea was very rare and present only in 2 (0.6%) of the tracheas.
The overall incidence of cestodes was slightly higher than those of nematode parasites. It was found to be 65.0% and 22.6% in desi (indigenous) and commercial (W.L.H) layers respectively.
The species of cestode with percentage of infection recovered from the small intestine of desi (indigenous) birds were:
Raillietina tetraona 58.0% (174/300)
Raillietina cesticillus 12.6% (38/300)
Raillietina echinobothrida 14.0% (42/300)
Cotugnia digonoora 10.8% (32/300)
Choanotaenia infundibulumn 20.0% (60/300)
Amoebotaenia sphenoides 3.3% (10/300)

Publisher: 1993Dissertation note: A study was under taken to find out the incidence of hydatidosis and to evaluate the efficacy of indirect haemagglutination (IHA) test for the confirmation of natural hydatidosis in sheep slaughtered at Lahore municipal abattoir.
Blood samples from 200 sheep (50 each from hydatidosis affected and free sheep on the basis of postmortem findings and 100 blood samples Elected randomly without considering postmortem finding). The serum from each sample was separated, properly labelled and stored at -20°C.
For the preparation of antigen, crude cyst fluid was aspirated aseptically from hydatid cysts. Blood from healthy sheep was collected in 3.8% sodium citrate solution and red blood cells were separated by centrifugation. A 2.5% red cell suspension was prepared in Phosphate Buffered Saline (PBS). The sheep erythrocytes were sensitized by Hydatid fluid antigen. Optimal dilution of antigen 1:16 was used in Phosphate Buffered Saline (p11 6.4) for sensitizing the sheep erythrocytes. All the sera were inactivated at 56°C for half an hour and serial two f1d serum dilutions were prepared by micropipettes in microtitre U plates and sensitized erythrocytes were added to the plates and incubated at room temperature in a humid chamber for 3 hours. A titre of 1:32 and above was considered as positive. In positive reactions, the cells agglutinated like a carpet at the bottom of the wells where as in negative cases the cells settled as a compact mass in the centre of the wells. By the indirect haemagglutination test Ninety-two percent sheep were found positive for hydatidosis. (Table-4.2). Out of 50 serum samples (Group A2), 46 (92%) were confirmed positive on postmortem while 3 out of 50 (6%) hydatid free samples (Group A3), gave false positive results with IHA test.
It was concluded that indirect haemagglutination test is an accurate, reliable and sensitive test (92%) for the diagnosis of hydatidosis in sheep.
The blood cell counts (TLC, DLC) and blood chemistry (Total protein, A/G ratio) of the samples under investigation were also carried out. From the results it was evident that the hydatid cysts did not affect the blood values of the host significantly. However, only 28% of hydatid positive animals showed eosinophilia ranging from 7 to 23% which was non pathognomonic.
It was thus inferred that blood cell counts and blood c1vmistry of the hydatid cyst patients was of no diagnostic value.

; Nature of contents: ; Literary form: Publisher: 1993Dissertation note: Ascaridia galli is the common intestinal nematode of poultry that causes severe losses in birds resulting in decreased weight gain and fall in egg production. These symptoms show that parasitic diseases are the constraints in the development of profitable poultry industry.
To find out the prevalence 300 chicken guts were obtained from different poultry meat shops in Lahore from May to August, 1993.
An overall prevalence of 60 percent was recorded in chicks. The incidence of infection was highest (73.3 percent) in the month of July and lowest (42.6 percent) in the month of May.
For conducting haematological examination one hundred and thirty-five chicks were purchased and reared under good hygienic conditions. At the age of 15 days chicks were divided into 3 groups (A, B and C). Chicks of groups A and B were infected with 50 and 100 eggs, respectively, while group C was taken as control. After 35 days of inducing experimental infection blood samples from all the three groups were taken at an interval of 5 days i.e., 35, 40 and 45 days postinfection to examine erythrocyte count, packed cell volume, haemoglobin level, total leukocyte count and differential leukocyte count.
Significantly lower values of erythrocyte count, packed cell volume and haemoglobin were estimated in infected groups A and B as compared to control group C, while higher values were obtained for heterophil, lymphocyte and eosinophil in infected chicks resulting in an overall increase in total leukocyte count. It was also estimated that A. gal/i produced no significant change in monocyte count.
Chicks from group A, B and C were weighed every week after infection to see the effect of A. gaili infection on body weight.
Results regarding body weight showed that there was significant decrease in weight in group A and B as compared to control group C and there was also significant decrease in group B as compared to group A.

Publisher: 1994Dissertation note: Pakistan has a large population of live stock, which plays an important role in the economy of the country. Parasitism adversally effects the growth and production of livestock. Great economic losses have been attributed to the sheep population in our country due to the parasitic infections including cestodes. A study of cestodal infections with taxonomy of the prevalent cestoctes species affecting sheep at different age groups in and around Lahore was conducted. The taxonomical study was conducted in the month of August, September and October, 1993. For this purpose 200 guts (one hurtdered each from below six month and above six month of sheep) were collected from Lahore Abattoir. Parasites were identitied under the microscope by preparing permanent mounts.
The over all incidence of cestodes infection in sheep was 65.5%.
The species of various genera of cestodes observed during the present
study were:
Moniezia pansa (64%), Moniezia benedeni (60%), Avitellina cjj[iur1ctta
(49.50%), Avitellina lahorea (40%), Avitellina sudanea (30%), Stilesia vittata
(30%), Stilesia globiounctata (50%) and Thvsanosoma actinioides (6%).
Monthwise prevalence of cestodes infection was also carried out and it was observed that the highest infection rate was (76%) during the month of August and (66.25%) during the month of September. While the lowest incidence was recorded as (57.14%) during the month of october, 1993.
The taxonomy of the prevalent cestode species was carried out. The effect of age of the animals on the intensity of cestodal infection was also studied. There was a significant difference in the prevalence of cestode infections among the two groups.
The present work was also aimed to verify the efficacy of two commonly available anthelmintics namely albendazole (valbazen) and niclosarnide (mansonil), in naturally infected stceep with Gastrointestinal cestocJes. Fifty sheep positive for cestods infections were randomly divided into two groups A and B, each group comprising of 25 animals. Group. A was given albendazole (valbazen) at a dose rate of 2.5 mg/kg body weight orally while the group B was administered niclosamide (mansonil) at a dose rate of 100 mg/kg body weight orally. The efficacy of both the drugs was evaluated on the bases of reduction of segments and number of eggs per gram of faeces after medication. The egg counts were made on zero, 3rd and 21st day. Both the drugs revealed a progressive decrease in the faccal egg/segment counts. The efficacy of albenclazole on 3rd and 21st day was 96.02 and 99.23% repectively while the efficacy of niclosamide (mansonil) was 100% on 3rd and 21st day.

Publisher: 1995Dissertation note: There is an increasing interest in pigeons and other game and ornamental birds. These birds are generally kept either free roaming or confined in outdoor pens and hence are vulnerable to various parasitic infectious, which greatly effects the productivity of these birds.
The meat production of the pigeons can be improved by controlling disease problems particularly helrninths and blood protozoan infections, so that in near future they may contribute towards narrowing down the animal protein supply gap by substituting poultry meat with squabs.
The present work was planned for the comparative study of helminths and heemoparasites of domestic and wild pigeons. For this purpose 300 each of guts and blood smears were studied. The overall incidence of gastrointestinal helminths and blood protozoans was 77.33% and 31.99% respectively, while 36% of birds had mixed infection. The incidence of gastro-intestinal helminths and blood protozoa in wild pigeons was 89.33 and 20.66 percent respectively and in domestic pigeons it was 65.33% and 11.33% respectively. Whereas mixed infections were 22% and 14% respectively.
The following species of helmitiths and blood protozoa were recorded and identified.
1. Raillietina tetragona
2. Raillietiiia cesticillus
3. Choanolaenia infundibulum
4. Ascaridia colurnbae and
5. Cap illaria obgnata
The two species of blood protozoa recovered were:
1. Aegypanella pullorum and
2. Haeiçotuscumbae
Among the helrninths recorded, cestodes were found predominating as compared with nernatodes in both wild and domestic pigeons. Raillietina cesticillus was the most common cestode species in both Wild and domestic pigeons i.e. 51 and 33 percent respectively while Asci colurnbae predominated the nernatode species i.e. 18 and 15 percent respectively. The Incidence was higher in wild pigeons.
Aegyptianella pullorum was more common blood protozoan i.e. 22 and 11 percent respectively in wild and domestic pigeons. The incidence of Haemoproteus clumbae was 9 and 11 percent respectively.

Publisher: 1996Dissertation note: Nature has blessed Pakistan with a large population of livestock which play an important role in the economy of the country. Parasitism adversely effects the growth and production of livestock. Great economic losses have been attributed to the sheep population in our country due to parasitic infections including gastro-intestinal parasitism. A study of gastro-intestinal parasitism with isolation and identification of the parasite species affecting sheep at different age groups in and around Lahore was conducted in the months of July, August, September and October, 1994.
For this purpose 200 G.I. tracts of sheep (One hundred each from below six months and above six months of age) were collected from Lahore Metropolitan Corporation, Abattoir.
The overall incidence of gastro-itestinal parasitism in sheep was found to be 68.5%. Age group wise incidence was found to be 71% and 66% in sheep below and above six months of age respectively. Classwise overall incidence was found to be Sporozoan (51%), Trematodes (21%), Cestodes (62%) and Nematodes (68%).
Age group wise incidence of Sporozoan, Trematodes, Cestodes and Nematodes was found to be 60% and 42%, 12% and 30%, 71% and 53%, 73% and 63% in sheep below and above six months of age.
Month-wise prevalence of gastro-intestinal parasitism was also carried out which was higher in the month of August and lowest in the month of October. Nineteen different species of Parasites were recorded which are detailed as under:
1. Eimeria arloingi
2. Eimeria ninakohlvakimovae
3. Eimerla parva
4. Elmerla intricata
5. Eimeria faurei
6. Paramphistomum cervi
7. Cotylophoron cotvlophorum
8. Moniezia. expansa
9. Moniezia benedeni
10. Avitellina centripunctata
11. Haemonchus contortus
12. Oesophagostomum colunThianum
13. Oesophagostonim venulosum
14. Trichuri
15. Ostertagia circumcincta
16. Ostertagia ostertagi
17. Chabertia ovina
18. Trichostrongvlus colubriformis
19. Nematodirus spathiger
The isolation and identification of various collected parasites was carried out. The relationship between the age of sheep and the occurrence of gestro-Intestinal parasitism was also studied. There was a Non Significant difference in the prevalence of gastro-intestinal parasites among the two groups.
The present project was also aimed to observe the effect of single or multiple parasitism on certain haematological parameters like, estimation of haemoglobin contents, total erythrocytic count, total leukocytic count, erythrocyte sedimentation Rate, packed cell volume and differential leukocytic count.
These heamatological studies were carried out on control (parasitic free) and parasitised sheep of below and above six months of age.
The findings of haematological studies showed that there was decrease in haemoglobin contents. total erythrocytic count, packed cell volume, total leukocytic count and increase in erythrocyte sedimentation rate in both sheep below and above six months of age under the effect of single or multiple gastrointestinal parasitism. The values of differential leukocytic count were variable in both age groups.
Most of the haematological disturbances on various blood parameters in both age group of sheep were proved to be statistically significant.
From the results of the presents study, it has been concluded that the incidence of gastro-intestinal parasitism in sheep below and above six months of age is on the higher side which warrants that certain essential preventive measures must be adopted to safeguard our valuable livestockfrom these serious parasitic infestations. It is also evident from the results that gastro-intestinal parasitism adversely affects the blood components in sheep which may lead to anaemia, loss of growth and loss of production.

Publisher: 1996Dissertation note: The study was designed to find the prevalence and intensity of liver fluke infection in buffaloes in Lahore District. The study period was from April 1995 to July 1995. The data was based on:
Data collected from four Veterinary Hospitals in Lahore District namely, Herbenspura, R.A. Bazar, Shamkey Bhattian and Rukh Chandra indicated that during the study period from 1 April, 1995 to 31 July, 1995, a total of 2184 buffaloes were treated for different diseases in these hospitals. Based on history, clinical symptoms and response to treatment 229 (10.48%) buffaloes were positive for fascioliasis.
Information collected from Municipal Corporation, Lahore abattoirs regarding economical losses revealed that one hundred eight million rupees were lost annually due to damage and condemnation of liver fluke infected livers.
Two hundred faecal samples collected directly from the rectum of buffaloes from various localities at Lahore were examined microscopically by fresh smear and sedimentation methods, which revealed that 75 (37.5%) buffaloes were suffering from fascioliasis.
In order to determine the intensity of Fascioliasis in infected animals, quantitative faecal examination was done (and it ranged from 32.6 to 45.6 EPG indicating that the disease is likely to be pathogenic).
Overall liver fluke infection was recorded by examining forty livers along with their bile ducts collected from slaughtered buffaloes and it was found that 16 (40%) had liver fluke infection.
Identification of live flukes from the infected flukes revealed that 8 (50%) had mixed infection of Fasciola hepatica and Fasciola gigantica, 5 (31.25%) had only Fasciola gigantica infection while 3 (18.75%) had only Fasciola hepatica infection.
It was concluded from the above studies that Fascioliasis in buffaloes in Lahore district is quite prevalent, and it needs to adopt appropriate measures to control the infection.

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: For this research project, about 305 fresh fertile hen eggs were obtained from Veterinary Research Institute, Lahore. These eggs after cleaning were incubated at 37°C in automatic incubator for 11 days. At the 11th day, candling was done to confirm the fertility of eggs, either they are embryonated or not,. Eggs found dead at the time of candling were discarded. Fertile eggs 305 in number were inoculated with physically and chemically treated mesogenic strain of Newcastle disease virus which had already been treated and stored in plastic vials at -20°C. Each egg was inoculated with about 0.lnil of the treated viral sample. Four eggs were set for each of the factor for each time period. Four eggs were kept control in each factor in which viral suspension without physical or chemical treatment was inoculated.
The project was designed to study the effect of physical and chemical factors on the survival of Newcastle disease virus. The physical factors were temperature, p11 and UV light and chemical factors included five disinfectants like Formaline, Iosan, Phenol Aldekol and Bromosept (QAC). It was noted that at 56°C temperature virus lost its haemagglutinating activity after 45 minutes, but survived this temperature at 15 and 30 minutes exposure. It was observed that virus survived at pH 4 and 9 for 6, 12, 18 and 24 hrs but was killed at pH 1 and 13 for all the said time periods. After exposing virus to UV light, it was examined that Newcastle disease virus survived at UV light exposure for 45 minutes.
As far as the chemical factors were concerned, the results showed that 0.48% concentration of formalin inactivated virus in 30 minutes but not in 15 minutes. Other two concentrations i.e. 0.12% and 0.24% could not inactivate the virus. Phenol and Bromosept showed good antiviral activity against ND virus. 0.4% and 0.6% concentrations of Phenol inactivated the virus within 15 minutes but virus retained its HA activity at 0.2% phenol concentrations for 15, 30 and 45 minutes. The virus survived at 0.1% Bromosept concentration for 45 minutes and at 0.5% concentration for 15 minutes time but its haemagglutinating property was lost at 0.5% concentration in 30 minutes and at 1% concentration, the virus was killed within 15 minutes time. 0.1% concentration of Aldekol could not inactivate the virus in 15, 30 or 45 minutes. At its 0.5% concentration virus was inactivated after 45 minutes exposure but not at 15 and 30 minutes. However 1% Aldekol inactivated virus after 30 minutes but not within 15 minutes time. losan with 0.5% and 1.0% concentrations killed the mesogenic strain of Newcastle disease virus in 15, 30 and 45 minutes respectively. So the results of this study show that losan shows excellent antiviral activity against ND virus and is the best for disinfection of this virus at the farm. Bromosept (QAC) and Phenol should be the other two options for farmers to disinfect their sheds and hatcheries to minimize the chances of infection from Newcastle disease virus.

Publisher: 1998Dissertation note: A study of gastro intestinal helminth parasites of sheep and goats of District Peshawar has been conducted, covering a period of 4 months (May to August, 1998). During this study incidence of GIT. helminths and their impact on production potential (weight gain) of sheep and goats was studied. Random collection of samples were made from Peshawar slaughter house and a total of 40 guts each in sheep and goats were examined and following species of helminths were recovered and identified. Oesophagostomum columbianum, 0. venulosum, Trichuris parvespiculum, Haemonchus contortus, Chabertia ovina, Bunostornum trigonocephalum, Nematodirus spathiger, Moniezia benedeni, Moniezia expansa, Trichuris lani, T. globulosa, Cysticercus tenuicollis.
Only two species of cestodes and nine species of nematodes were recorded during the study. However no trematode specie was recorded. Amongst the nematodes Trichiurisparuespiculum infection was recorded to be the highest in sheep and goats with an incidence of 64.70% and 73.33% respectively. The incidence of Haemonchus contortus was 24.19 and 53.33% in sheep and goats respectively. The worm burden ranged from 1-470 in sheep and 3-141 in goats respectively.
Out of total gastro intestinal tracts examined (40 each in sheep and goats), 73.33% and 60.29% were found positive for mixed infection in sheep and goats respectively.
In order to assess the effect of GIT helminths on live weight gain and its measurement in terms of economics of the above mentioned animals, 0 Hasthnagri sheep and 30 beetal goats were divided into two groups (control vs. treated by Nilzan Plus of ICI). The average daily weight gain in sheep group was 83.78 gms while in goats it. was 85.26 gms per animal. On comparison with treated group, the increase weight gain was 3.03 kg and 2.56 kg in sheep and goats respectively at the end of the experiment. Calculating the increase on live weight basis Rs.234.5 and 158 per animal were earned more in sheep and goats respectively. After deducting the cost of anthelmintic treatment the net gain Rs.222.5 and Rs.146 per animal in sheep and goats. During this study a progressive decrease in faecal egg counts with increasing age was observed both in sheep and goats.
Statistical analysis by using un-paired "t" test confirmed that there was significant differences in weight gain and faecal egg counts, between control and treated groups of sheep and goats.

Publisher: 1998Dissertation note: The study was conducted to determine the prevalence of genus trypanosome and the effects of natural infection on some blood parameters in dogs.
For this purpose blood samples of 500 pet dogs (250 adult dogs and 250 pups) were examined at Dog Hospital, College of Veterinary Sciences, Lahore. Giemsa staining procedure was admpted to stain glass slides having blood smears made from blood samples.
Out of 500 ogs, 30 dog were found positive for tryponosomiasis. It revealed that only 6% prevalence of trypanosomiasis in dogs was estimated. In case of adult dogs out of 250 dogs, 13 dogs (5.2%) and in pups out of 250 dogs, 17 dog (6.2%) were found trypanosome infected. So pups were found more susceptible as compared to adult dogs. During research it was also noticed that mot of the dogs which were found positive being kept with horses.
Then blood samples of 10 adult dogs and pups each which wre positive for trypanosomiasis and 10 adult dogs and pups each which were healty (as control) were further examined for the estimation of haemoglobin paced cell volum, erythrocytes sedimentation rate and total serum protein to check the effects of natural infection on mentioned blood parameters.
The blood parameters of trypanosome infected and healthy adult dogs were compared and similarly blood parameters of trypanosome infected and healthy pups were compared. For this comparison unpaired 't' test was applied. By calculation it was found that haemoglobin, packed cell volume and total serum protein of trypanosome infected adult dogs and pups were significantly decreased as compared to healthy adult dogs and pups, respectively. But the erythrocytes sedimentation rate was found significlantly increased in case of trypanosome infected adult dogs and pups as compared to healty, adult dogs and pups.

Publisher: 1999Dissertation note: The present study was conducted to see the effects of the experimentally induced coccidiosis on weight gain and some blood parameters and its control with medication and vaccination. For this purpose, 150 day-old quail chicks were purchased from the local hatchery and were reared under control managemental and coccidiosis free condition upto the 42 days of experiment. A commercial coccidiostat free feed and drinking water were provided ci libitum throughout the experiment. The birds were divided in five separate groups i.e. A, B, C, D and E, each comprising of 30 birds. Group A was kept as a non-infected, non-medicated and non- vaccinated. The chicks of groups B, C, D and E, were administered 50,000 oocysts of. tenella directly into the crop at the 18 days of age, the chicks in group C were immunized against coccidiosis with a locally prepared vaccine on 3rd and 10th day of age, while those of group D with an imported coccidiosis vaccine (Coccivac) on 7th day of age. The chicks of group E were medicated with Salinomycin on the appearance of clinical symptoms and OPG of the infected birds.
No oocysts were seen in the droppings of group A chicks, throughout the experiment, while group B, chicks had the highest OPG count after induction of infection, the highest peak being in the 3rd week post-infection.
The highest mortality recorded in the infected B group and low in other infected C, D and E groups and highest mortality in 3rd week of induced infection in all infected groups.
The birds in groups A and E attained highest weight gain as compared with groups B, C and D but the difference was non significant.
The lowest Hb and TEC values were recorded in infected group B, while in other infected groups C, D and E both these values were also decreased but comparatively lesser than B group. Similarly, values of TLC were increased in infected group B as compared with other infected groups i.e. C, D and E and the difference was statistically significant.
In case of differential leukocyte counts there were increased heterophil and monocytes values in group B, while decreased values lymphocytes, basophils and eosinophils were recorded in other infected groups than the other i.e. C, D and E.
The postmortem lesions observed were swollen intestines petechial haemorrhages on the wall of the intestine and dehydrated liver and lungs in infected carcasses.

Publisher: 1985Dissertation note: Haemonchosis is a serious helminthic infection of sheep and goats resulting in the mortality due to excessive blood loss and causes great economic losses. The objective of the present study was to determine the effect of natural infection of Haemonchus contortus in sheep upon blood haemo- globin, serum iron and magnesium level so that it could aid in accurate diagnosis and effective therapeutic measures. Infection was confirmed through faecal examination. Eggs per gram of faeces were calculated by McMaster egg counting technique. To see the effect of severity of infection on these blood components, blood samples of positive cases were taken from jugular vein.
Blood haemoglobin, serum iron and magnesium were estimated by using standard diagnostic kits with spectrophotometer. A decreased level of haemoglobin and serum iron was directly proportional to the severity of infection. However, no alteration in serum magnesium level was observed in infected and non-infected animals.
