Novel plasmid-mediated colistin resistance mcr-4 gene in Salmonella and Escherichia coli, Italy 2013, Spain and Belgium, 2015 to 2016

A novelmcr colistin resistance gene was identified in a strain ofSalmonella enterica, monophasic variant of serovar Typhimurium (4,5,12:i:-?), isolated from a pig at slaughter in Italy in 2013, and inEscherichia coli strains collected during routine diagnostic of post-weaning diarrhoea in pigs from Spain and Belgium in 2015 and 2016. Immediate implementation ofmcr-screening including this novel gene variant is required forSalmonella andE. coli from humans and food-producing animals in Europe.
