In spring 2009 several cases of infestation with Ornithonyssus bacoti («tropical rat mite») in pet rodents have been diagnosed at the Institute of Parasitology, University of Zurich. Although adequate animal hosts were present, owners also became victims of mite infestation. The owners presented cutaneous lesions such as pruritic red papules partly with a central vesicle, predominantly disposed in groups. Particularly children with close body contact to their pet rodents were strongly affected. Because the definite diagnosis was usually yielded at a late time-point, the medical treatment remained unsatisfactory in some cases. The mite-infestation of the pets was mostly detected after the owners also became affected. The owners noticed merely non-specific signs such as increased restlessness, itching and shaggy coat on their animals. Efficient healing was achieved only if the parasites were completely eliminated, i.e. also the pets were treated, the cages cleaned and the apartments professionally disinfested. A definite diagnosis of «Infestation with Ornithonyssus bacoti» is only possible by means of morphological identification on an isolated mite, which is most likely to be found in the environment of the animals. Pet owners should be informed about the zoonotic potential of O. bacoti.
2009年春季，苏黎世大学寄生虫学研究所诊断出几例宠物啮齿动物感染柏氏禽刺螨（“热带鼠螨”）的病例。尽管有合适的动物宿主，但宠物主人也成为了螨虫感染的受害者。主人出现皮肤病变，如瘙痒的红色丘疹，部分伴有中央水疱，主要成群分布。特别是与宠物啮齿动物有密切身体接触的儿童受到的影响较大。由于通常在较晚的时间点才能做出明确诊断，因此在某些情况下，药物治疗效果并不理想。宠物的螨虫感染大多是在主人也受到感染后才被发现。主人只是注意到动物有一些非特异性症状，如躁动增加、瘙痒和被毛蓬乱。只有彻底清除寄生虫，即对宠物进行治疗、清洁笼子并对住所进行专业消毒，才能实现有效治愈。只有通过对分离出的螨虫进行形态学鉴定才能明确诊断为“柏氏禽刺螨感染”，而螨虫最有可能在动物的生活环境中被发现。应告知宠物主人柏氏禽刺螨的人畜共患病潜力。
