Co-production of MCR-1 and NDM-1 by Escherichia coli sequence type 31 isolated from a newborn in Moscow, Russia

An Escherichia coli sequence type 31 isolate co-harbouring mcr-1 and bla(NDM-1) genes on the plasmids of Incl2 and IncC groups, respectively, was recovered from a newborn with ventilator-associated pneumonia in Moscow, Russia. The convergence of polymyxin and carbapenem resistance and its expansion beyond Southeast Asia is a serious threat to human health. (C) 2020 The Author(s).
