40 Echinococcus isolates from sheep and cattle in Southern Brazil were genetically analysed in order to obtain further data on the presence of different taxa of the Echinococcus granulosus complex. Differentiation was done using a PCR technique and sequencing of mitochondrial cytochrome c oxidase subunit 1 (CO1). Most samples (38) could be allocated to the sheep strain (G1) of E. granulosus, while two samples belonged to E. ortleppi, previously known as cattle strain (G5) of E. granulosus. Due to the shorter prepatent period in dogs of the latter taxon, this records have important implications for the design of control measures in this endemic region.
对巴西南部绵羊和牛身上的40株棘球绦虫分离株进行了基因分析，以便获取有关细粒棘球绦虫复合体不同分类群存在情况的更多数据。采用聚合酶链反应（PCR）技术和线粒体细胞色素c氧化酶亚基1（CO1）测序进行鉴别。大多数样本（38个）可归为细粒棘球绦虫的绵羊株（G1），而两个样本属于奥氏棘球绦虫，以前称为细粒棘球绦虫的牛株（G5）。由于后一个分类群在犬类中的潜伏期较短，这些记录对该流行地区控制措施的设计具有重要意义。
