Abstract:
The present report describes a case of Echinococcus multilocularis infection in nutria (Myocastor coypus) culled in the central area of Slovenia. Post-mortem exam showed multiple cystic lesions in the liver. Gross examination, as well as parasitological and histopathological examinations, revealed numerous cysts of various sizes, filled with yellow clear fluid and displacing most of the liver parenchyma. The cyst lumina contained numerous protoscolices approximately 100 μm in diameter and calcareous corpuscles. The protoscolices had two visible suckers and a rostellum with birefringent hooks. The lesions were consistent with an E. multilocularis cyst. Molecular analysis confirmed that the nutria was infected with E. multilocularis. To our knowledge, this is the first report of echinococcosis in nutria in Slovenia that presents gross, parasitological, and histological lesions and the result of molecular analysis. Nutrias in Slovenia are dangerous invaders but can also be a relevant bioindicator of the presence of the parasite in the environment.
摘要:
本报告描述了在斯洛文尼亚中部地区扑杀的nutria(Myocastorcoypus)中多房棘球蚴感染的病例。尸检显示肝脏有多个囊性病变。总检查,以及寄生虫学和组织病理学检查,发现了许多不同大小的囊肿,充满黄色透明液体,置换大部分肝实质。囊肿腔包含许多直径约100μm的原头囊和钙质小体。原型具有两个可见的吸盘和一个带有双折射钩的rostellum。病变符合多房性E.囊肿。分子分析证实营养液被多房性大肠杆菌感染。据我们所知,这是斯洛文尼亚营养品中棘球蚴病的第一份报告,寄生虫学,组织学病变和分子分析的结果。斯洛文尼亚的营养盐是危险的入侵者,但也可能是环境中寄生虫存在的相关生物指标。
