Abstract

Present study was conducted to explore the gross and histopathological lesions in intestine of goats naturally affected with parasitic infections in eastern plain zone of Uttar Pradesh. The post-mortem examination of dead goats was conducted for any gross lesions in intestine and samples showing lesions suggestive of parasitic infections were collected and preserved in 10% buffer formalin saline solution for histopathological study. Grossly, haemorrhagic and erosive lesions along with sloughed ruminal mucosa and papilla, severe to moderate haemorrhag¬es and thickened mucosal wall, blood mixed faeces or intestinal contents were noticed in the intestine. Microscopically, intestine showed congestion of vessels, haemorrhages, necrosis of intestinal epithelium, blunting of intestinal villi with desquamation of epithelium from mucosal surface. Hyperplasia of goblet cell, necrosis and replacement of glands of Leiberkuhn’s by inflammatory cells mainly mononuclear cells were also noticed. Lesions were more common in jejunum and ileum except in Trichuris infection in which lesion was common in caecum. Affected villi and crypts of intestine also revealed different developmental stages of coccidian oocyst infiltration of mononuclear cells (monocytes and lymphocytes) in cases of coccidiosis.

Conclusion

It may be concluded from gross and histopathological study of intestine in goats died due to diarrhoea that major changes occur in small intestine and are characterized by congestion, haemorrhages, necrosis of crypts, desquamation of epithelial cells, blunting of villi with infiltration of inflammatory cells mainly mononuclear cells. Developmental stages are also found in affected tissues in case of coccidiosis. The pathological changes observed in cases of coccidiosis, amphistomiasis, strongyles and Trichuris infections might help in differential diagnosis with other infections viz., salmonellosis, giardiasis, coronavirus infections, tapeworm infections, cryptosporidiosis. In field condition, post-mortem examination provides correct and rapid diagnosis on the basis of characteristics and pathognomic lesions.
