Fig. 2: Distribution and trend over time of ESC-R genes in E. coli by compartment.

a Trends in percentage and b count for ESC-R types over time in Canada and France across humans and farm animals (cattle, chickens, pigs and turkeys). The lines and bars are coloured by ESC-R types. c Trends over time of the percentage of the major ESC-R gene in main compartments (colour key is in inset legend). Source data are available in the Source Data file. ESC-R extended-spectrum cephalosporin resistance, ESBL extended-spectrum β-lactamases.
