Evaluation of a Screening Method for the Detection of Colistin-Resistant Enterobacteriaceae in Stool

Open Forum Infect Dis. 2019 May 6;6(6):ofz211. doi: 10.1093/ofid/ofz211. eCollection 2019 Jun.


Emergence of mobile colistin resistance (mcr)-containing Enterobacteriaceae is a public health threat, prompting enhanced surveillance through the Centers for Disease Control and Prevention. We evaluated a selective culture medium for the isolation of Enterobacteriaceae with non-wild-type colistin minimum inhibitory concentrations, including those with mcr-1 genes, in spiked stool samples.
