Abstract: The atypical enteropathogenic Escherichia coli (EPEC), a subgroup of EPEC, has the ability to cause histopathologic attaching and effacing lesions in eukaryotic cells, but lacks the virulence-associated EPEC adherence factor plasmid. The aEPEC strains may harbor virulence markers of other Diarrheagenic E. coli pathogroups as well as of extraintestinal pathogenic E. coli strains. This observation led to the assumption that aEPEC strains comprise a very heterogeneous group with diverse additional virulence mechanisms that altogether can modulate ...
