Cystic Echinococcosis (CE) caused by the larval stages of taeniid cestodes of the genus Echinococcus is a neglected helminth zoonosis affecting humans and various animal species. The aim of this study was to assess the fertility of cattle from two provinces in the northeast and southwest of Iran, and molecularly characterize the hydatid cysts collected from them. From 5000 carcasses of naturally infected cattle inspected from October 2013 to December 2015, 70 hydatid cysts were collected in Mashhad in the northeast and 50 from Ahvaz in the southwest. All 120 samples were identified as E. granulosus senso stricto (G1, common sheep strain) by PCR-RFLP analysis and sequencing of the ITS1 gene. All cysts recovered from these animals were sterile, highlighting the lower importance of cattle in the transmission of the “sheep strain”. The fact that that the zoonotic E. granulosus s.s. is dominant makes CE an important public health concern in Iran.
由棘球绦虫属幼虫阶段引起的囊型包虫病（CE）是一种被忽视的人畜共患蠕虫病，影响人类和多种动物物种。本研究的目的是评估伊朗东北部和西南部两个省份牛的感染率，并对从这些牛身上采集的包虫囊肿进行分子特征分析。在2013年10月至2015年12月期间检查的5000头自然感染牛的尸体中，在东北部的马什哈德采集到70个包虫囊肿，在西南部的阿瓦士采集到50个。通过PCR-RFLP分析和ITS1基因测序，所有120个样本均被鉴定为狭义细粒棘球绦虫（G1，普通绵羊株）。从这些动物身上回收的所有囊肿均不育，这突出表明牛在“绵羊株”传播中的重要性较低。人畜共患的狭义细粒棘球绦虫占主导地位这一事实使囊型包虫病成为伊朗重要的公共卫生问题。
