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)
While in conimercial (W.L.H) layers
Raillietina tetraona
Raillietina cesticillus
Raillietina echinobothrida
Cotunia dionopora
Choanotaenia infundibuluni
Anioebotaenia sphenoides
they were:
22.0% (66/300)
1.0% (3/300)
3.0% (9/300)
1.0% (3/300)
4.3% (13/300)
2.0% (6/300)
No trematode parasites was however recovered both in
desi (indigenous) and commercial (W.L.H.) birds during the
present study.

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: 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: 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.
