Abstract

A surveillance study for diagnosis of C. perfringens enteritis affecting early weaned rabbits was carried out on sixteen rabbit flocks, during the period 2012 - 2014. Two hundred and sixty seven rectal swabs from diseased rabbits suspected to be infected with C. perfringens, moreover tissue samples from intestine and liver of 48 freshly dead rabbits were aseptically collected for isolation, biochemical and molecular identification of C. perfringens. Tissue specimens from small, large intestine, liver, spleen and kidney from each examined freshly dead rabbits were processed for histopathological examination. The examined breeds were (baladi, french, california, bauscat, chinchilla, new - zealand and dutch) with age ranged from 3-9 weeks and mortality rate 12 - 60%. Observed clinical signs were severe diarrhea and bloat. Postmortem lesions showed different degrees of enteritis, liver and kidney congestion with enlargement. Histopathological alterations were necrohemorrhagic enteritis in small and large intestine, portal congestion, periportal edema, sinusoidal dilatation and hepatic hemorrhage in liver, depletion and necrosis of lymphoid elements in spleen and degeneration in the tubular epithelium, vacuolization of epithelial lining of renal pelvic with perivascular edema in kidney
