Rapid Polymyxin NP test for the detection of polymyxin resistance mediated by the mcr-1/mcr-2 genes

Diagn Microbiol Infect Dis. 2018 Jan;90(1):7-10. doi: 10.1016/j.diagmicrobio.2017.09.012. Epub 2017 Sep 22.

Abstract

The Rapid Polymyxin NP test has been recently developed to rapidly detect polymyxin resistance in Enterobacteriaceae. Here we evaluated this test for detecting MCR-1/MCR-2-producing Enterobacteriaceae using a collection of 70 non-redundant strains either recovered from the environment, animals, or humans. Sensitivity and specificity were found to be 100%.

Keywords: Enterobacteriaceae; MCR; Polymyxin; Rapid Polymyxin NP test; Resistance.
