Example Sentences
Recent Examples on the Web About a decade ago, doctors needing a last-resort antibiotic turned to an old but still-effective antibiotic called colistin to cure highly resistant infections. 
Wired, 19 Sep. 2019 While India’s drugs technical advisory board, part of the ministry of health and family welfare, has recommended that colistin and other antimicrobials should not be used in agriculture, there is no formal ban. Ranjit Devraj, Quartz India, 23 July 2019 The researchers also sequenced the genomes of bacteria resisting colistin and those susceptible to it. Beth Mole, Ars Technica, 9 Mar. 2018 In fact, the bacteria is resistant to the last-resort antibiotic colistin. Reuters, Newsweek, 26 May 2016 Across the world, researchers in China have documented colistin-resistant Shigella flexneri, a form of bacteria that causes severe diarrhea and was discovered on a pig farm. Matthew Wellington, STAT, 19 Mar. 2018 Researchers at Emory University found that a common type of resistant bacteria, Klebsiella pneumoniae, can mask resistance to colistin. Matthew Wellington, STAT, 19 Mar. 2018 This isn’t the first time scientists have identified bacterial heteroresistance to colistin. Betsy Mckay, WSJ, 6 Mar. 2018 Recent reports cite different forms of bacteria in both people and animals resisting colistin, an antibiotic that doctors prescribe when other treatment options fail.
