Abstract
Intestinal pathogenic Escherichia coli is a major causative agent of severe diarrhea. In this study the prevalences of different pathotypes among 702 E. coli isolates from Brazilian patients with diarrhea were determined by multiplex PCR. Interestingly, most strains were enteroaggregative E. coli (EAEC) strains, followed by atypical EPEC (ATEC) strains. Classical enteropathogenic E. coli (EPEC) strains were not detected.
摘要
肠致病性大肠杆菌是严重腹泻的主要病原体。在这项研究中，通过多重 PCR 方法检测了来自巴西腹泻患者的 702 株大肠杆菌分离株中不同血清型的流行情况。有趣的是，大多数菌株为聚集性肠产毒性大肠杆菌（EAEC）菌株，其次是非典型性肠致病性大肠杆菌（ATEC）菌株。未检测到经典肠致病性大肠杆菌（EPEC）菌株。
