RESUMO
A total of 12 adult buffaloes were presented for the necropsy over the period of 6 months at the Department of Veterinary Pathology, CGKV, Anjora, Durg, Chhattisgarh. Prevalence of Gigantocotyle spp. parasite infection was found to be 16.67% (2/12). Significant number of parasites was found in the bile duct and ductules of the infected liver along with the necrotic debris caused by parasite. Other gross lesions observed were included hepatitis, haemorrhages and fibrosis of the liver. Black color hard nodules at the site of mucosal attachment of parasites were noticed. Microscopic changes observed were included bile duct hyperplasia, haemorrhages, moderate fibrosis and granulomatous nodule characterized by infiltration of inflammatory cells
RESUMO
The objective of the study was to evaluate the acute toxicity of lambda cyhalothrin in rat. Male albino rats were exposed to 80 mg/kg body weight of lambda cyhalothrin by means of gavage. The toxicological manifestations include myocardial hyalinisation, lysis of reticular framework in spleen, and spermatogonial cell degeneration in testes.
