A [new report](http://www.thelancet.com/journals/laninf/article/PIIS1473-3099%2815%2900424-7/abstract "undefined") found bacteria resistant to colistin, a drug used when all other treatments have failed, in 16 patients, 15% of raw meat samples and a fifth of the animals tested. The mutation that made the bacteria resistant to the drug is called the MCR-1 gene, and spread resistance between various bacteria including E. coli. Prof Timothy Walsh of the University of Cardiff, who worked on the study [told BBC](http://www.bbc.com/news/health-34857015 "undefined"), “All the key players are now in place to make the post-antibiotic world a reality. If MCR-1 becomes global, which is a case of when not if, and the gene aligns itself with other antibiotic resistance genes, which is inevitable, then we will have very likely reached the start of the post-antibiotic era. At that point if a patient is seriously ill, say with E. coli, then there is virtually nothing you can do.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4120064/mutation-bacteria-drug-resistant/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4120064/mutation-bacteria-drug-resistant/"},"headline":"Newly Discovered Bacteria Can Resist All Antibiotics","datePublished":"2015-11-19T13:56:38.000Z","dateModified":"2026-02-22T12:46:14.743Z","description":"A mutation discovered in people and livestock in China makes bacteria resistant to last-resort drugs","url":"https://time.com/4120064/mutation-bacteria-drug-resistant/","keywords":["medicine","Drugs","Bacteria"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt24fc3a1e7983062d/69886f312dce012ab29e64b6/e-coli-outbreak.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Tessa Berenson","jobTitle":null,"url":"https://time.com/author/tessa-berenson/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt24fc3a1e7983062d/69886f312dce012ab29e64b6/e-coli-outbreak.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"E Coli","caption":"E Coli","creditText":"Ian Cuming—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/medicine/","name":"medicine"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4120064/mutation-bacteria-drug-resistant/","name":"Newly Discovered Bacteria Can Resist All Antibiotics"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"New Antibiotic Kills TB, MRSA Without Building Resistance","description":"Researchers published findings on teixobactin on Wednesday.
