An infestation with Raillietia auris in a 4 years old cow is reported. For a period of 3 weeks the animal showed an increasing unrest, extreme efforts while trying to feed, and continuous shaking of the head which slanted to the left. After slaughter numerous specimens of the ear-mite R. auris were found in the basic part of the left auditory canal, located in the vicinity of a purulent paste-like plug. Histological examinations of the brain revealed a severe non-purulent meningoencephalitis with necroses of the vascular walls, focal malacia and gliosis. An etiological correlation of these lesions with the mite-infestation, however, is considered to be most unlikely. To the best of our knowledge the occurrence of R. auris in Switzerland was up to now unknown.
报道了一头4岁奶牛感染耳螨(Raillietia auris)的病例。在3周的时间里,这头奶牛表现出越来越不安,进食时极度费力,并且持续摇头,头偏向左侧。屠宰后,在左耳道基部发现了大量耳螨(R. auris)标本,该部位靠近脓性糊状堵塞物。对脑部进行组织学检查发现严重的非化脓性脑膜脑炎,伴有血管壁坏死、局灶性软化和胶质增生。然而,这些病变与螨虫感染之间的病因学关联被认为极不可能。据我们所知,耳螨(R. auris)在瑞士的出现此前并不为人所知。
