For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient's foot infection. The mechanism, called MCR-1, was incorporated into a plasmid, a short piece of DNA that exists independent of the genome, which can jump from one bacterium to another, spreading the resistance.
