Abstract
We isolated 47 Acinetobacter strains carrying tet(X3) and 4 ST767 E. coli strains carrying tet(X4) from 296 rectal swab samples from dairy cows on a Chinese farm. tet(X3) was located on chromosomes or diverse plasmids, and tet(X4) was located on IncFIBΚ/FIA(HI1)/X1 nontransferable plasmid. The coexistence of tet(X3) and carbapenemase genes, including blaOXA-58 and blaNDM-1, was detected in 9 Acinetobacter spp. These findings suggested that the use of tetracycline and other antibiotics in food production warrants urgent attention.
