ABSTRACT
The present observation was recorded at National Research Centre on Mithun, Jharnapani from May 2010 to September 2012. A total of 15 mithun calves, which died in and around Jharnapani, were attended and detailed post-mortem examination was carried out. Out of these, five calves (33.33 %) aging between 1 and 1.5 years exhibiting the condition of chronic wasting and diarrhoea were found positive for pimply gut condition based on gross and microscopic examination. Post-mortem examination revealed extensive nodule formation on the wall of the rectum; however, the entire lumen did not reveal any of adult parasites. In all the cases, there were congestion in the mucous layer and thickening of the intestinal wall. Histopathological examination revealed chronic enteritis with mononuclear cell infiltration comprising mostly of macrophages, lymphocytes and eosinophils. In the muscularis mucosae, encysted larvae were found along with fibrous tissue proliferation. These lesions gave the intestine a nodular appearance as they thickened the wall and projected from the serosal surface. These extensive numbers of nodules in the intestine might have interfered with peristalsis and intestinal absorption which led to chronic wasting and diarrhoea in the calves.
