An infestation with Otodectes cynotis, the ear mite of cats and dogs, was observed in three free-ranging Eurasian lynx (Lynx lynx) killed in Sweden. The ear canals were obstructed by waxy secretions and exfoliated epithelium. Histologically, there were hyperkeratosis and acanthosis, and the epithelial surface was overlained by hyperkeratotic and parakeratotic crusts with mites, mite detritus and cerumen. In the subcutis there was a slight to moderate infiltration of lymphocytes and macrophages. The ceruminous glands were bypertrophic and hyperplastic, and there was also an hyperplasia of the sebaceous glands. The lesions seemed to correlate with the degree of infestation. To our knowledge, this is the first report of otoacariasis in free-ranging lynx.
在瑞典捕杀的三只自由放养的欧亚猞猁（猞猁属）身上观察到感染了犬耳螨，即猫和狗的耳螨。耳道被蜡样分泌物和脱落的上皮组织阻塞。组织学检查显示，存在角化过度和棘皮症，上皮表面覆盖着有螨虫、螨虫碎屑和耳垢的角化过度和不全角化痂皮。皮下组织有轻度至中度的淋巴细胞和巨噬细胞浸润。耵聍腺肥大和增生，皮脂腺也有增生。病变似乎与感染程度相关。据我们所知，这是关于自由放养猞猁耳螨病的首次报告。
