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.
对来自意大利皮埃蒙特一个保护区（包括波河）的90只被困海狸鼠（Myocastor coypus）进行了检查，以确定主要内脏器官的病变患病率、特定血清抗体和肠道细菌情况。肝脏中的球虫病变包括胆管炎、钙化和坏死。肾脏病变为非化脓性间质性肾炎，还有一例肾腺癌。肺部非化脓性间质性肺炎的患病率为41.1%。87份血清中有10份（11.5%）含有抗布拉迪斯拉发钩端螺旋体的抗体，87份中有3份（3.4%）含有抗出血性黄疸钩端螺旋体的抗体，41份中有15份（36.6%）含有抗弓形虫的抗体，78份血清中有5份（6.4%）检测到抗脑心肌炎病毒的抗体。所有粪便样本的沙门氏菌、志贺氏菌和假单胞菌检测均为阴性，肠杆菌科细菌的生长在正常范围内。
