Abstract
This study aims to characterize the presence of virulence factors of enterotoxigenic Escherichia coli (ETEC) causing traveler's diarrhea. Among 52 ETEC isolates, the most common toxin type was STh, and the most frequent colonization factors (CFs) were CS21, CS6, and CS3. On the other hand, the nonclassical virulence factors EAST1 and EatA were frequently present.
摘要
本研究旨在描述引起旅行者腹泻的肠产毒性大肠杆菌（ETEC）毒力因子的存在情况。在 52 株 ETEC 分离株中，最常见的毒素类型是 STh，最常见的定植因子（CFs）是 CS21、CS6 和 CS3。另一方面，非经典毒力因子 EAST1 和 EatA 也经常存在。
