64.3% K. pneumoniae isolates were the K1 serotype, 19.6% were the K2 serotype, and the rest were the non-K1/K2 serotype. The dominant sequence type was ST23 in the K1 serotype (34/36). Within the K2 serotype, ST65, ST86 and ST375 accounted for 27.3% of isolates, respectively. Others included one ST374 isolate and one ST380 isolate
