Gastrointestinal parasitism of goats in hilly region of Meghalaya, India

Abstract

Aim: The aim of this study was to determine the prevalence of gastrointestinal (GI) parasitic infections in goats of hilly region of Meghalaya. Materials and Methods: A total of 834 fecal samples of goats were screened for 1 year (2014-2015) using flotation techniques. Results: The overall prevalence of GI parasitic infections in goats was 28.65%. Season-wise highest infections were recorded during rainy season (34.92%) followed by cool (26.87%), hot (26.62%), and cold (20.39%) seasons. Helminths and protozoa infections were recorded in 63.60% and 23.02% animals, respectively. Among the helminths, Strongyle spp. (32.63%) was recorded highest followed by Trichuris spp. (12.55%), Moniezia spp. (10.04%), and Trichuris spp. (8.36%). Among protozoa, only Eimeria spp. was detected. Seven different species of Eimeria spp. were identified, viz., Eimeria christenseni, Eimeria hirci, Eimeria caprina, Eimeria jolchijevi, Eimeria ninakohlyakimovae, Eimeria arloingi, and Eimeria kocharii for the first time from Meghalaya. Maximum egg per gram and oocyst per gram of feces were recorded in the month of August (932.4) and September (674.05), respectively. Mixed infections were recorded in 13.38% samples. Coproculture of goat fecal samples revealed the presence of Haemonchus contortus (72.16%), Oesophagostomum spp. (14.41%), Strongyloides spp. (8.91%), and Trichostrongylus spp. (4.50%) larvae. Conclusion: This study indicates that GI helminths and protozoa infections are prevalent in goats of this hilly region of Meghalaya, throughout the year and highly prevalent during rainy season.
