From July 2017 to January 2019, total of 645 retail fresh vegetables collected from 19 retail shops and markets was investigated to know the contamination of enterohemorrhagic Escherichia coli (EHEC) and enterotoxigenic E. coli (ETEC). Of 645 samples, 2 samples (0.3%) were positive for pathogenic E. coli. Of 2 pathogenic E. coli positive samples, 1 was EHEC (stx2 positive) and the other was ETEC (sta positive). Two pathogenic E. coli strains were isolated from crisphead lettuce. EHEC strain was not serotyped by commercial antisera and ETEC was serotyped as O20. EHEC and ETEC strains showed multi-drug resistance against 4 and 7 antibiotics, respectively. These results indicate that retail fresh vegetables seem to be not an important source of human EHEC and ETEC infection in the Mekong Delta, Vietnam. |
