Parasitic Infections and Diagnostics

Gastrointestinal (GI) parasitism in small ruminants is one of the major problems in the Indian subcontinent.The resent study was designed to generate prevalence data on GI parasitism of sheep in 7 different districts comprising 6 Agroclimatic zones of Assam, India.During 24 months study period, out of 334 faecal samples examined, 123 were found to be positive for gastrointestinal parasites (prevalence 36.82%) and the highest prevalence recorded was 47.14% in Biswanath Chariali district and lowest 20% in Dhubri district.In sheep, prevalence was found highest in North Bank Plain (47.14%) followed by Hills Temperate (40.74%) and Lower Brahmaputra Valley (32.38%).Age wise prevalence was 48.29 % in adults and 18.60% in young.Sex wise prevalence indicated that the females were slightly more infected i.e. 39.15%, than the males (33.79%).Species of gastrointestinal nematode eggs recorded on microscopic examination of faecal samples were viz.Chabertia ovina, Trichuris ovis, Trichostrongylus spp., Haemonchus contortus and Oesophagostomum spp.eggs amongst the Strongyle nematodes, oocysts of coccidia and amphistome eggs amongst the trematodes.Chabertia ovina was found to be the predominant species.
