Abstract

Three VIM-2-producing Enterobacteriaceae (two Enterobacter cloacae and one Klebsiella oxytoca) isolates recovered from patients in a Mexican hospital were characterized during the SENTRY Antimicrobial Surveillance Program (2005-2007). These strains carried identical bla(VIM-2) integrons in a 450-kb plasmid. The interspecies dissemination of this bla(VIM-2)-harboring element emphasizes the potential for spread of genetic structures carrying metallo-beta-lactamases that could limit therapeutic options in this geographic region.
