| Abstract: | Autotransporter (AT) protein-encoding genes of diarrheagenic Escherichia coli (DEC) pathotypes (cah, eatA, ehaABCDJ, espC, espI, espP, pet, pic, sat, and tibA) were detected in typical and atypical enteropathogenic E. coli (EPEC) in frequencies between 0.8% and 39.3%. Although these ATs have been described in particular DEC pathotypes, their presence in EPEC indicates that they should not be considered specific virulence markers. |
