Multilocus sequence typing (MLST) was carried out as described previously (http://bigsdb.web.pasteur.fr/klebsiella/primers_used.html; Diancourt et al., 2005). Briefly, Seven hosekeeping genes (gapA, infB, mdh, pgi, phoE, rpoB, and tonB) for K. pneumoniae were amplified, sequenced, and analyzed. Alleles and STs were determined according to the database (http://bigsdb.web.pasteur.fr/perl/bigsdb/bigsdb.pl?db=pubmlst_klebsiella_seqdef_public&page=profiles). STs that could not be found in the database were submitted to the curator of the database (klebsiellaMLST@pasteur.fr). eBURST version 3.0 software was used to analyze the clustering of related STs. In this study, isolates were grouped together if six of the seven alleles were homologs.
