Prevalence of Ec with ESBL and mcr genes in humans and animals. The prevalence of samples with Ec with the three most frequent bla _ESBL genes (CTX-M-14, CTX-M-55, and CTX-M-15) are shown in pig farmers, chicken farmers, and non-farmers (control) (Fig. 1a). The numbers for animal samples are illustrated for small- (SF) and very small-sized farms (VSF) (Fig. 1b). The prevalence of samples with Ec with mcr genes (MCR-1.1, MCR-3.5, and other mcr) are also shown for humans (Fig. 1c) and animals (Fig. 1d). The 95 % confidence intervals are indicated. Statistical significances were determined using a chi-square test.
