The coypu (Myocastor coypus Molina) is an aquatic rodent that has become a widespread pest in the south-east of England. Since the natural habitat of this animal is aquatic, the possibility of infection with leptospires was investigated. Twenty-nine coypu were trapped and examined by serological, histological and cultural methods. Of these, there was serological evidence of infection in seven coypus and Leptospira interrogans var. Wolffii was isolated from a further animal. This appears to be the first report of the isolation of leptospira from a coypu in Great Britain.
河狸鼠（Myocastor coypus Molina）是一种水生啮齿动物，已成为英格兰东南部广泛分布的有害动物。由于这种动物的自然栖息地是水生环境，因此对其感染钩端螺旋体的可能性进行了调查。捕获了29只河狸鼠，并通过血清学、组织学和培养方法进行检查。其中，7只河狸鼠有感染的血清学证据，并且从另一只动物中分离出了沃尔夫氏问号钩端螺旋体。这似乎是英国首次从河狸鼠中分离出钩端螺旋体的报告。
