We isolated 47 strains carrying (X3) and 4 ST767 strains carrying (X4) from 296 rectal swab samples from dairy cows on a Chinese farm. (X3) was located on chromosomes or diverse plasmids, and (X4) was located on IncFIBκ/FIA(HI1)/X1 nontransferable plasmid. The coexistence of (X3) and carbapenemase genes, including and , was detected in 9 spp. These findings suggested that the use of tetracycline and other antibiotics in food production warrants urgent attention.
