Coypus (Myocastor coypus) are widespread throughout Europe. In northern Italy, they are abundant in the flatland areas, and their high population densities can cause economic loss and ecosystem damage. We examined 153 coypus for selected parasitic and bacterial infections. We found Strongyloides myopotami (63.4% prevalence), Trichostrongylus duretteae (28.1%), Eimeria coypi (86.3%), and Eimeria seideli (6.8%), but did not find Giardia duodenalis or Cryptosporidium spp. We also isolated Staphylococcus aureus (10.1%), Escherichia coli (4.5%), and Streptococcus spp. (3.4%) from lung samples; no Salmonella spp. were isolated from fecal samples. Coypus had antibodies to Toxoplasma gondii (28.9%) and to four serovars of Leptospira interrogans (44.9%); Australis/Bratislava was the serovar most frequently detected. It is clear that coypu can be infected with pathogens of human and veterinary importance.
河狸鼠（Myocastor coypus）在欧洲广泛分布。在意大利北部，它们在平原地区数量众多，其高种群密度会造成经济损失并破坏生态系统。我们检查了153只河狸鼠是否感染特定的寄生虫和细菌。我们发现了肌圆线虫（Strongyloides myopotami，感染率63.4%）、杜氏毛圆线虫（Trichostrongylus duretteae，28.1%）、河狸艾美球虫（Eimeria coypi，86.3%）和塞氏艾美球虫（Eimeria seideli，6.8%），但未发现十二指肠贾第虫或隐孢子虫属。我们还从肺样本中分离出了金黄色葡萄球菌（10.1%）、大肠杆菌（4.5%）和链球菌属（3.4%）；粪便样本中未分离出沙门氏菌属。河狸鼠对刚地弓形虫有抗体（28.9%），对四种问号钩端螺旋体血清型有抗体（44.9%）；澳大利亚/布拉迪斯拉发血清型是最常检测到的血清型。显然，河狸鼠可能感染对人类和兽医具有重要意义的病原体。
