Distribution of non-LEE-encoded type 3 secretion system dependent effectors in enteropathogenic Escherichia coli

Braz J Microbiol. 2014 Oct 9;45(3):851-5. doi: 10.1590/s1517-83822014000300014. eCollection 2014.

Abstract

Enteropathogenic Escherichia coli (EPEC) are important human gastroenteritis agents. The prevalence of six non-LEE genes encoding type 3 translocated effectors was investigated. The nleC, cif and nleB genes were more prevalent in typical than in atypical EPEC, although a higher diversity of genes combinations was observed in atypical EPEC.

Keywords: diarrhea; enteropathogenic Escherichia coli (EPEC); pathogenicity; type 3 secretion system.
