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 bla OXA-58 and bla NDM-1 , was detected in 9 Acinetobacter spp. |
