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.
