Carbapenem-resistant Enterobacterales (CRE) pose a serious threat to clinical management and public health. We investigated the molecular characteristics of 12 IMP-4 metallo-β-lactamase-producing strains, namely, 5 Enterobacter cloacae , 3 Escherichia coli , 2 Klebsiella pneumoniae , and 2 Citrobacter freundii . These strains were collected from a tertiary teaching hospital in Zhengzhou from 2013 to 2015. The minimum inhibitory concentration (MIC) results showed that each bla IMP - 4 -positive isolate was multidrug-resistant (MDR) but susceptible to colistin...
