Outbreak of NDM-1-Producing Klebsiella pneumoniae in a Neonatal Unit in Colombia

Abstract

ABSTRACTSix multiresistant, NDM-1-producingKlebsiella pneumoniaestrains were recovered from an outbreak that affected six neonatal patients in a Colombian hospital. Molecular analysis showed that all of the isolates harbored theblaNDM-1,qnrA, andintI1genes and were clonally related. Multilocus sequence typing showed that the isolates belonged to a new sequence type (ST1043) that was different from the sequence types that had previously been reported. This is the first report of NDM-1-producing isolates in South America.
