Carbapenemase-Producing Enterobacteriaceae in Yunnan Province, China.

Among 144 carbapenem-resistant Enterobacteriaceae strains isolated from 4 hospitals in Yunnan province, 113 were identified as carbapenemase-producing Enterobacteriaceae (CPE). Bla (99/113, 87.6%) was the most common carbapenemase gene and Klebsiella pneumoniae (100/113, 88.5%) was the most common species. Bla (11/113, 9.7%), bla (10/113, 8.8%), and bla (1/113, 0.9%) genes were also detected. Extended-spectrum β-lactamase genes were common in CPE, and the SHV- and CTX-M-types were predominant.
