Emergence of KPC-producing Klebsiella pneumoniae hypervirulent clone of capsular serotype K1 that belongs to sequence type 11 in Mainland China

KPC-2 has been rarely reported in hypervirulent Klebsiella pneumoniae strains. Here, we describe a KPC-2-producing K. pneumoniae hypervirulent clone of capsular serotype K1 belonging to sequence type 11. The presence of KPC carbapenemase in hypervirulent clone could mark an evolutionary step toward its establishment as major nosocomial pathogen.
