Ninety trapped nutria (Myocastor coypus) from a protected area of Piedmont (Italy), including the Po river, were examined for the prevalence for lesions in major viscera, selected serum antibodies and enteric bacteria. Coccidial lesions in the liver included cholangitis, calcification and necrosis. Renal lesions were nonsuppurative interstitial nephritis and a single case of renal adenocarcinoma. The lungs had a 41.1% prevalence of nonsuppurative interstitial pneumonia. Ten of 87 sera (11.5%) had antibodies against Leptospira bratislava, 3 of 87 (3.4%) against Leptospira ichterohaemorrhagiae, 15 of 41 (36.6%) against Toxoplasma gondii, and antibodies against encephalomyocarditis virus were detected in 5 of 78 sera (6.4%). All fecal samples were negative for Salmonella, Shigella, and Pseudomonas, and growth of enterobacteriaceae was in the normal range.
