Seasonal and genotypic changes in escherichia coli phylogenetic groups in the Yeongsan River basin of South Korea.

With 3,480 E. coli strains isolated from the Yeongsan River basin, South Korea, correlations between phylogenetic groups and horizontal fluorophore enhanced rep-PCR (HFERP) genotypes were examined, and environmental factors affecting E. coli phylogenetic groups in the river water were determined. In...
