A STUDY ON INCIDENCE OF GASTROINTESTINAL PARASITES IN BUFFALOES FROM DIFFERENT SLAUGHTER HOUSES OF CHITTAGONG METROPOLITON.

Abstract

Buffaloes are the food animals commonly slaughtered in the abattoirs throughout Chittagong city. Various gastrointestinal parasitic infestations usually occur in them. Therefore a total of 100 fecal samples were collected from three slaughter houses and studied by coproscopic examination drudging the period of December 2010 to January 2011 with a view to find out the incidence of parasitic gastrointestinal parasites here. Direct smear, sedimentation and floatation techniques along with egg micrometry were conducted to identify various parasitic eggs in the laboratory of Department of Pathology and parasitology, Chittagong Veterinary and Animal Sciences University. Out of 100 fecal samples 70% were positive for different individual parasitic infestation. Trematodes, nematodes, cestodes and protozoan infestations were 50%, 15%, 2% and 3% percent respectively. Among the trematodes parasitism with Schistosoma sp 25%, Paramphistomum sp 15%, and Fasciola sp 10% . Incidence of nematodal infestations were 4% Toxocara sp, 3% Cooperia sp, 3% Oesophagostomum sp, , 3% Bunostomum sp. and 1 % for both Trihostrongylus sp and trongyloides sp. Mixed infection were observed among 7% of positive samples. This result indicates the heavy worm burden in buffaloes causing severe economic loss to the farmers by reducing the overall productivity.
