Abstract

Paa (porcine attaching and effacing associated) may be an important virulence factor E. coli of piglets with diarrhea. This study showed for the first time in Brazil the prevalence of the paa gene (22%) in E. coli strains isolated from piglets and these isolates also harboured genes for other adhesins and toxins LT II, STa and STb.

摘要

Paa（猪附着和破坏相关）可能是仔猪腹泻致病性大肠杆菌的一个重要毒力因子。本研究首次在巴西显示了从仔猪分离的大肠杆菌菌株中 paa 基因（22%）的流行，这些分离株还携带其他黏附素和毒素 LT II、STa 和 STb 的基因。
