Distribution of putative extraintestinal pathogenic E. coli (ExPEC) virulence factor genes (VFGs) compared to non-ExPEC associated VFGs among E. coli STs from Alameda County, CA hospital patients from 2017–2019. (A) Putative ExPEC virulence genes representing 19 sub types from seven virulence gene families (afa, fim, hlyD, iutA, kpsM, traT, pap, sfa) were selected for sub-analysis. The average number of ExPEC VFGs among all STs was calculated and displayed as the dashed blue y-intercept line, with a value of 35.68 ExPEC VFGs per ST. (B) The relative abundance of each virulence gene is the total length of the virulence gene sequence divided by the total genome sequence length. The mean value of relative abundance was calculated by ST.
