MLST of K. pneumoniae was performed according to Protocol 2 described on the MLST website1. The seven housekeeping genes (gapA, infB, mdh, pgi, phoE, rpoB, and tonB) of K. pneumoniae were amplified by PCR with primers in Protocol 2. Sequence types (STs) were determined by using the K. pneumoniae MLST database of Institut Pasteur2. To identify the capsular types of K. pneumoniae strains, the wzi allele was amplified, and the obtained sequences were aligned to the wzi sequences deposited in the database of Institut Pasteur (Brisse et al., 2013)2.
