AI Article Synopsis
- A study screened 1840 Enterobacteriaceae isolates from food sources in Portugal for colistin resistance from 2010 to 2015.
- The mcr-1 gene was found in 8.0% of E. coli and 0.47% of Salmonella enterica isolates, with many E. coli also producing other resistance enzymes.
- No mcr-2 gene was found, indicating that the mcr-1 gene is a significant concern in the spread of antibiotic resistance in food-producing animals and meat.
Article Abstract
We screened 1840 Enterobacteriaceae isolates from food-producing animals, meat, meat products and animal feed, for the detection of plasmid-mediated colistin resistance, during 2010-2015. The mcr-1 gene was detected in 8.0% (97/1206) Escherichia coli and in 0.47% (3/634) Salmonella enterica isolates, with a high number of mcr-1 positive E. coli isolates (45.7%) being extended-spectrum β-lactamase or plasmid-mediated AmpC β-lactamase co-producers. No mcr-2 gene was detected. Our findings highlight the spread of mcr-1 genes within a wide-ranging sample of food-producing animals and meat, in Portugal.
