Clostridium perfringens type E is considered a rare toxinotype and an infrequent cause of enterotoxemia of lambs, calves, and rabbits. Until now, only cases of young animal of C. perfringens type E bovine enterotoxemia, characterized by hemorrhagic enteritis and sudden death, have been reported. The present report details the genotypic characterization of C. perfringens type E isolates obtained from intestinal samples of adult cattle during an outbreak of enterotoxemia in Argentina. The sequences of several housekeeping genes of these isolates were analyzed and compared with those obtained from calves in North America showing a clonal unique lineage.
产芽胞梭菌 E 型被认为是一种罕见的毒素型，也是羔羊、犊牛和兔肠毒血症的不常见病因。到目前为止，仅报道了几例产芽胞梭菌 E 型牛肠毒血症的幼年动物病例，其特征为出血性肠炎和突然死亡。本报告详细介绍了在阿根廷肠毒血症暴发期间从成年牛肠道样本中获得的产芽胞梭菌 E 型分离株的基因特征。分析了这些分离株的几个管家基因的序列，并与北美的犊牛分离株进行了比较，显示出一种独特的克隆谱系。
