Comparative genomic analysis of enterotoxigenic Escherichia coli O159 strains isolated from diarrheal patients in Korea

ConclusionsSerotype of NCCP15731 and NCCP15733, representing major types of ETEC in Korea, was O159:H34 and their MLST type was ST218. Comparison with other O159 strains revealed that NCCP15731 was specialized for transporter system and secretion system whereas NCCP15733 had unique genes related to capsular polysaccharide. Compared with E159, the most recent common ancestor, these two strains had different toxin type and virulence factors. These results will improve our understanding of ETEC O159 strains to prevent ETEC disease.
