Three metacestodes were collected from the mesentery and the surface of the liver of three adult alpacas (Vicugna pacos) in a slaughterhouse located in Puno, Peru. Various features of the metacestodes were observed for morphological identification. A molecular diagnosis was performed by PCR-based sequencing of mitochondrial genes of cytochrome c oxidase subunit 1 (cox1) and the NADH dehydrogenase subunit 1 (nad1). All metacestodes were identified as Taenia omissa by morphology and molecular methods The isolates from alpacas showed significant sequence similarity with previously reported isolates of T. omissa (95.7-98.1% in cox1 and 94.6-95.1% in nad1). Our report is the first to detect T. omissa metacestodes in alpacas and to reveal that alpacas are natural intermediate hosts for this parasite.
在秘鲁普诺的一家屠宰场，从三只成年羊驼（小羊驼）的肠系膜和肝脏表面采集到了三个绦虫蚴。观察了绦虫蚴的各种特征以进行形态学鉴定。通过基于聚合酶链反应（PCR）的细胞色素c氧化酶亚基1（cox1）和烟酰胺腺嘌呤二核苷酸脱氢酶亚基1（nad1）线粒体基因测序进行分子诊断。通过形态学和分子方法，所有绦虫蚴均被鉴定为遗漏带绦虫。来自羊驼的分离株与先前报道的遗漏带绦虫分离株显示出显著的序列相似性（cox1为95.7 - 98.1%，nad1为94.6 - 95.1%）。我们的报告首次在羊驼中检测到遗漏带绦虫蚴，并揭示羊驼是这种寄生虫的天然中间宿主。
