Full genome sequence of pT3, a multiresistant plasmid carrying the mcr-3.5 colistin resistance gene, recovered from an extended-spectrum-β-lactamase-producing Escherichia coli isolate from crickets sold as food

In: Microbiology Resource Announcements, 2019/8/29/e00647-19, /mra/8/29/MRA.00647-19.atom

Here, we sequenced multidrug resistance plasmid pT3, which encodes mcr-3.5 and other resistance genes. The cooccurrence of mcr genes and other resistance genes on a single plasmid is of concern.

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%.

Key features of mcr-1-bearing plasmids from Escherichia coli isolated from humans and food

Zurfluh, Katrin ; Nüesch-Inderbinen, Magdalena ; Klumpp, Jochen ; Poirel, Laurent ; Nordmann, Patrice ; Stephan, Roger

In: Antimicrobial Resistance & Infection Control, 2017, vol. 6, p. 91

Mcr-1-harboring Enterobacteriaceae are reported worldwide since their first discovery in 2015. However, a limited number of studies are available that compared full-length plasmid sequences of human and animal origins.
