A team of investigators have isolated colistin-resistant Escherichia coli from a commercial poultry farm in China. Colistin is an antibiotic of last resort against certain bacteria. The research is published in the journal Antimicrobial Agents and Chemotherapy.
In the study, as part of ongoing surveillance, the researchers from Key Laboratory of Sichuan Province, Sichuan University collected rectal swabs from randomly selected chickens in multiple commercial chicken farms in China.
The researchers found that E. coli from the chickens often carried multiple resistance genes, including one copy of the colistin-resistance gene mcr-1, and one copy of the resistance gene, mcr-3. This is the first report of these two genes on a single plasmid. | READ MORE
