Department of Defense researchers disclosed Thursday in a report placed online by the journal Antimicrobial Agents and Chemotherapy that a 49-year-old woman who sought medical care at a military-associated clinic in Pennsylvania last month, with what seemed to be a urinary tract infection, was carrying a strain of E. coli that possessed resistance to a wide range of drugs. That turned out to be because the organism carried 15 different genes conferring antibiotic resistance, clustered on two “mobile elements” that can move easily among bacteria. One element included the new, dreaded gene mcr-1.
The discovery “heralds the emergence of truly pan-drug resistant bacteria,” the DOD personnel, Patrick McGann, PhD of the Walter Reed Army Institute of Research and Kurt Schaecher, PhD of the Walter Reed National Military Medical Center, along with eight colleagues, write in the journal report.
