The gel electrophoresis images of PCR product of the phylogenetic groups and virulence genes. A The PCR profiles were specific to the phylogenetic groups of E. coli. The determination of a strain’s phylogenetic group was achieved through the amplification of the chuA and yjaA genes, as well as the DNA fragment TSPE4.C2. The negative control was included in Lane NC. B PCR was used to detect virulence genes
