Colistin resistance genes mcr-1 to mcr-5, including a case of triple occurrence (mcr-1, -3 and -5), in Escherichia coli isolates from faeces of healthy pigs, cattle and poultry in Belgium, 2012-2016.

Abstract excerpt

Colistin is a last-resort antimicrobial used to treat infections caused by multidrug-resistant Gram-negative bacilli (MDR-GNB). The emergence of colistin resistance, particularly linked to mobile genetic elements including the mcr genes, is a major threat to the management of MDR-GNB infections. The aim of this study was to assess the presence of mcr genes in a collection of 40 colistin-resistant commensal...
