An adult, female, free-ranging, sika deer (Cervus nippon yakushimae) from Wicomico County, Maryland, USA, was found circling and having no fear of humans. The animal was euthanized and submitted for a postmortem exam. There were no gross lesions and the deer was negative for rabies. Microscopic examination revealed lymphoplasmacytic, neutrophilic, and eosinophilic meningoencephalitis with intralesional adult nematodes, larvae, and eggs consistent with nematodes in the family Protostrongylidae. Parelaphostrongylus tenuis was identified by polymerase chain reaction and DNA sequencing. To our knowledge, this is the first report of P. tenuis-associated encephalitis in a sika deer.
一只来自美国马里兰州威科米科县的成年雌性散养梅花鹿（日本梅花鹿亚种）被发现绕圈行走且不怕人类。这只动物被安乐死并送去进行尸检。没有肉眼可见的病变，这只鹿的狂犬病检测呈阴性。显微镜检查显示为淋巴细胞性、嗜中性和嗜酸性脑膜脑炎，病变内有成虫线虫、幼虫和虫卵，与原圆科线虫相符。通过聚合酶链反应和DNA测序鉴定为细颈线虫。据我们所知，这是梅花鹿中首例与细颈线虫相关的脑炎报告。
