Extended-Spectrum β-Lactamase Genes of Escherichia coli in Chicken Meat and Humans, the Netherlands
Figure 2. Multilocus sequence typing patterns of Escherichia coli from chicken meat, other meat types, human rectal swabs, and human blood cultures, the Netherlands. A) All E. coli containing extended-spectrum β-lactamase genes; B) E. coli containing blaTEM-52; C) E. coli containing blaCTX-M-1; D) E. coli containing blaCTX-M-15. Major sequence types are shown as numbers. Black connecting lines indicate single-locus variants; gray connecting lines indicate double-locus variants; dashed connecting lines indicate strains with >3 loci that are different; and shadowing indicates that >2 sequence types belong to 1 complex.
