Scientists have identified bacterial genes that lead to antibiotic resistance, including several that can be resistant to most powerful antibiotics, in air samples from Beijing, which is frequently cloaked in heavy smog,
    科學(xué)家已經(jīng)在來自北京的空氣樣本中鑒定出導(dǎo)致抗生素抗藥性的細(xì)菌基因，包括可以對(duì)抗抗生素的細(xì)菌基因，這種細(xì)菌基因時(shí)常隱藏在濃重的霧霾之中。
    Researchers from the University of Gothenburg in Sweden analysed 864 DNA samples taken from humans, animals and environments worldwide and found Beijing smog carried the largest number and types of genes identical or highly similar to antibiotic resistance genes (ARG).
    來自瑞典哥德堡大學(xué)的研究人員分析了來自全世界的人類、動(dòng)物和環(huán)境的864個(gè)DNA樣本，發(fā)現(xiàn)北京的霧霾中攜帶的與抗生素抗藥性基因(ARG)相同或高度相似的基因數(shù)量且種類最多。
    Microbial communities from Beijing smog harboured as many as 64.4 different types of ARG.
    來自北京霧霾的微生物群擁有多達(dá)64.4種不同類型的抗生素抗藥性基因。
    The researchers also identified in the Beijing smog metagenomes that contained several genes resistant to carbapenems, a class of last-resort antibiotics for treating challenging bacterial infections.
    研究人員還鑒定出北京霧霾的元基因組中含有幾種具有碳青霉烯類抗藥性的基因，碳青霉烯類是用于治療具有挑戰(zhàn)性細(xì)菌感染最后求助的抗生素。
