BookPublisher: 2000Subject(s): Department of ParasitologyDDC classification: 0721,T Dissertation note: The study was undertaken to assess the prevalence and taxonomy of the gastro-intestinal tract helminths in 200 sparrows that were naturally parasitized. In addition, the blood examination was carried out to record the effect of worm infestation on different blood parameters namely Haemoglobin (Hb) estimation, Total leukocyte count (TLC), Packed cell volume (PCV) and Differential leukocyte count (DLC) and these values were compared with the normal values.
Two hundred sparrows purchased from the market were kept in cages in Parasitology Section, College of Veterinary Sciences, Lahore. The birds were slaughtered at due intervals. Blood was collected and gastro-intestinal tract was searched for the collection and identification of the helminthic species.
The results revealed that out of 200 sparrows, 120 had the worm infestation, showing an overall incidence as 60%. The worms collected were subjected to the taxonomical study which was carried out in the laboratory of PaLrasitology Section.
Two species namely Ascaridia galli (36%) and Heterakis gallinarum (24%) were found inhabiting the small intestine and caeca of the infested birds, respectively. No trematodes and cestodal species were recorded from the GIT of these experimental sparrows. Blood examination revealed slight increase in TLC and Heterophils, while basophils and monocytes were not affected. However, Hb levels, PCV and lymphocytes showed decrease resulting into anaemia and retarded growth of the affected birds versus non-infected ones.
The eggs per gram (EPG) ranged between 200-1000 in case of Ascaridia galli and 400-1000 in Heterakis gallinarum infestation in naturally parasitized sparrows. The main EPG count recorded was 516.666 and 660.41 in case of Ascardia galli and Heterakis gallinarum infestation, respectively.
