Escherichia coli from Crohn's disease patient displays virulence features of enteroinvasive (EIEC), enterohemorragic (EHEC), and enteroaggregative (EAEC) pathotypes.

ABSTRACT:

Background

Escherichia coli is a normal inhabitant of the gut which upon acquiring virulence factors becomes potentially able to cause diseases. Although E. coli population augments in Crohn's disease (CD), the reason of this proliferation is not yet clear. CD associated E. coli shows features of extraintestinal pathogenic categories (ExPEC), and eventually the ability to invade cultured epithelial cells, a property observed among diarrheagenic E. coli (DEC). In this work, data on the characterization of an E. coli isolate from a CD patient reveal that, besides invasiveness, CD associated E. coli may harbor other typical DEC markers, namely those defining enterohemorragic (EHEC) and enteroaggregative (EAEC) pathotypes.
