Distribution of virulence genes in C-I, other cryptic clades and recently defined Escherichia species. a Pie chart showing the distribution of the STEC and ETEC hallmark virulence genes in C-I strains. b Grid charts showing the numbers of virulence genes other than the hallmark virulence genes identified in C-I, other cryptic clades and recently defined species. C-I strains were grouped into four pathotypes. STEC: STEC-type, ETEC: ETEC-type, Hybrid: STEC/ETEC hybrid-type, Non: nontypeable. c Distribution of virulence genes in C-I strains from humans and livestock animals (bovine, poultry and swine)
