Characterization of the novel optrA-carrying pseudo-compound transposon Tn7363 and an Inc18 plasmid carrying cfr(D) in Vagococcus lutrae.

To the best of our knowledge, we report the first identification of the cfr(D) and optrA in Vagococcus. Two novel oxazolidinone resistance gene-carrying mobile genetic elements, Tn7363 and pBN31-cfrD, were identified in V. lutrae BN31. Considering their transmission potential, attention should be paid to the risk of transfer of the optrA and cfr(D) genes from V. lutrae to clinically more important bacterial pathogens.
