Multilocus Sequence Types and Virulence Determinants of Hypermucoviscosity-Positive Klebsiella pneumoniae Isolated from Community-Acquired Infection Cases in Harbin, North China.

We investigated the molecular epidemiologic characteristics and virulence of hypermucoviscosity-positive Klebsiella pneumoniae in mainland China. We detected 16 hypermucoviscosity-positive strains in 65 total clinical isolates (24.62%). We found that 68.75% (11/16) of the positive strains had K2 genotype and carried the rmpA and iucA genes.
