Abstract excerpt
Two types of fimbriae, designated aggregative adherence fimbria I and II (AAF/I and AAF/II) have been described in enteroaggregative Escherichia coli (EAEC) strains. These fimbriae mediate the aggregative pattern of adherence (AA) to epithelial cells. The genes encoding the structural subunit of each fimbria have been designated aggA and aafA, respectively. The prevalence of these genes was investigated in 155...
