Abstract

ABSTRACT Cephalosporin-resistant Vibrio alginolyticus was first isolated from food products, with β-lactamases encoded by bla PER-1 , bla VEB-1 , and bla CMY-2 being the major mechanisms mediating their cephalosporin resistance. The complete sequence of a multidrug resistance plasmid, pVAS3-1, harboring the bla CMY-2 and qnrVC4 genes was decoded in this study. Its backbone exhibited genetic homology to known IncA/C plasmids recoverable from members of the family Enterobacteriaceae , suggesting its possible origin in Enterobacteriaceae .
