“Background Enteroaggregative E. coli (EAEC) is defined by its adhesion to cultured cells in a stacked Tryptophan synthase brick-like formation [1]. This phenotype, termed aggregative adherence (AA), is mediated by specific fimbriae (AAF) encoded by plasmids (pAA) [2, 3]. However, other factors, including afimbrial adhesins, are also associated with this adherence pattern, indicating its complex nature [4, 5]. The virulence of at least some prototype EAEC strains has been demonstrated [6], although it remains unclear whether virulent strains can be accurately screened in epidemiological studies. The gene sequence termed CVD432, found in pAA plasmids, has been employed as an EAEC molecular marker while the transcriptional activator termed AggR has been described as the major EAEC-virulence regulator [7].
