Phylogenetic group distribution and prevalence of virulence genes in Escherichia coli isolates from food samples in South Korea.

Abstract excerpt

We analyzed the distribution of phylogenetic groups of foodborne Escherichia coli isolates. We also investigated the prevalence of virulence-associated genes of diarrheagenic E. coli. In total, 162 E. coli isolated from foods (raw meat, fish, and processed foods) were collected in Korea. Approximately 90% of the foodborne isolates belonged to phylogenetic groups A and B1, whereas 1.2% were allocated to group B2,...
