Researchers from the Walter Reed National Military Medical Center in Maryland discovered a strain of E. coli that carried 15 different genes that confer antibiotic resistance, including the resistance factor MCR, which confers resistance to colistin, a drug of last resort.
This particular E. coli was recovered from the urine of a 49-year-old woman.
The paper is currently available as an accepted manuscript posted online.
