Carbapenemase-Producing Enterobacteriaceae in Yunnan Province, China

Abstract

Among 144 carbapenem-nonsusceptible Enterobacteriaceae isolated from 4 hospitals in Yunnan province, 113 were carbapenemase-producing Enterobacteriaceae (CPE). Bla_KPC-2 (99/113, 87.6%) was the most common carbapenemase gene and Klebsiella pneumoniae (100/113, 88.5%) was the most common species. Bla_NDM-1 (11/113, 9.7%), bla_IMP-4 (10/113, 8.8%), and bla_IMP-1 (1/113, 0.9%) genes were also detected. The extended-spectrum β-lactamase (ESBL) is common in CPE, SHV- and CTX-M- were the predominant type.
