Abstract

Cysticercosis caused by the larval form of the Taenia hydatigena tapeworm poses a global challenge to the livestock industry. A total of 56 goats slaughtered in Khishig-Undur, Mongolia were evaluated for the presence of cystic lesions. Collected cysts were assessed using the mitochondrial 12S rRNA gene. In total, 46.4% (26/56) of evaluated goats were positive for T. hydatigena infection, with most cysts attached to the omentum, mesentery, liver, or spleen. Partial 12S rRNA gene sequences were obtained from all evaluated cysts and aligned with known sequences for T. hydatigena. Infection prevalence was higher in goats three years of age and older (50.0%; 17/34) compared to goats less than three years of age (40.0%; 9/22) (p=0.035). Infection with T. hydatigena appears to be highly prevalent in goats in Khishig-Undur. Additional studies are needed to evaluate local parasite transmission dynamics and the impact of this parasite on local livestock production.

蒙古奇西格-乌都尔山羊水蛭的分子鉴定

由水蚤绦虫幼虫引起的囊尾蚴病是畜牧业面临的全球性挑战。我们对蒙古Khishig-Undur屠宰的56只山羊进行了囊肿病变评估。利用线粒体 12S rRNA 基因对收集的囊虫进行了评估。在接受评估的山羊中，46.4%（26/56）对 T. hydatigena 感染呈阳性，大多数囊肿附着在网膜、肠系膜、肝脏或脾脏上。从所有评估的囊肿中获得了部分 12S rRNA 基因序列，并与已知的 T. hydatigena 序列进行了比对。三岁及三岁以上山羊的感染率（50.0%；17/34）高于三岁以下山羊（40.0%；9/22）（p=0.035）。在 Khishig-Undur 的山羊中，T. hydatigena 感染似乎非常普遍。需要进行更多的研究，以评估当地寄生虫的传播动态以及这种寄生虫对当地畜牧业生产的影响。
