Eighteen months ago, a gene that confers resistance to colistin — known as an ‘antibiotic of last resort’ — emerged in bacteria from pigs in China. Since then, the resistance gene, called mcr-1, has been found around the world at an alarming rate, according to several presentations at the American Society for Microbiology (ASM) meeting in New Orleans, Louisiana, last week.

In some places, nearly 100% of farm animals carry mcr-1, and an increasing number of people do as well. The gene’s spread is one of the clearest examples of how antibiotic use on farms can lead to resistance in human infections , says Lance Price, an antibiotic researcher at George Washington University in Washington DC.

For the first time, researchers have found a person in the United States carrying bacteria resistant to antibiotics of last resort, an alarming development that the top U.S. public health official says could mean “the end of the road” for antibiotics.

The antibiotic-resistant strain was found last month in the urine of a 49-year-old Pennsylvania woman. Defense Department researchers determined that she carried a strain of E. coli resistant to the antibiotic colistin, according to a study published Thursday in Antimicrobial Agents and Chemotherapy, a publication of the American Society for Microbiology. The authors wrote that the discovery “heralds the emergence of a truly pan-drug resistant bacteria.”
