Prevalence of mcr-1 in E. coli from Livestock and Food in Germany, 2010–2015

As part of resistance monitoring of zoonotic pathogens and naturally occurring germs in the intestine of animals (commensal bacteria), implemented as a Federal/Länder-programme, Colistin resistance has been systematically studied since 2010. In the time period from 2010 to 2015, the highest proportion of Colistin-resistant pathogens was detected in E. coli from the turkey (11.7 %) and chicken meat chains (6.0 %). The proportion of resistant bacteria in this area has been marked by a slight decrease. In isolates from the foodchains of pigs (1.4 %) and veal (1.8 %), Colistin resistance was observed less frequently. For breeding poultry, in the beef cattle chain and for dairy products, this resistance gene has not been detected in Germany yet. A study of isolates tested by the BfR showed that of the E. coli isolates which resistance testing had shown to be Colistin-resistant, the majority was carrying the transferrable gene mcr-1.
