Early Dissemination of NDM-1- and OXA-181-Producing Enterobacteriaceae in Indian Hospitals: Report from the SENTRY Antimicrobial Surveillance Program, 2006-2007

Abstract
Among 39 carbapenem-resistant Enterobacteriaceae (2.7% overall; Escherichia coli, Enterobacter cloacae, and Klebsiella pneumoniae strains) isolated in 2006 and 2007 in India, 15 strains carried bla NDM-1 and 10 harbored a gene encoding a variant of the carbapenemase OXA-48, named bla OXA-181. One E. cloacae strain harbored bla VIM-6, and one K. pneumoniae strain carrying bla OXA-181 also possessed bla VIM-5. Multiple pulsed-field gel electrophoresis patterns and clonal dissemination within and among sites were observed. Isolates producing NDM-1 were disseminated in Indian health care facilities as early as 2006.
