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.
