瑞典報告稱北京霧霾有60餘種耐藥菌
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,
科學家已經在北京的空氣樣本中鑑定出導致抗生素抗藥性的細菌基因，包括可以對抗最強抗生素的細菌基因，這種細菌基因時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的研究人員分析了來自全世界的人類、動物和環境的864個DNA樣本，發現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量最大且種類最多。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羣擁有多達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.
研究人員還鑑定出北京霧霾的元基因組中含有幾種具有碳青黴烯類抗藥性的基因，碳青黴烯類是用於治療具有挑戰性細菌感染最後求助的抗生素。"This may be a more important means of transmission than previously thought," Joakim Larsson, who led the research, said in a statement.
主導這項研究的喬吉姆·拉爾森在一份聲明中表示：“空氣可能會是抗生素耐藥性傳播的重要途徑，而這之前沒有被意識到。”Larsson is a professor at the Sahlgrenska Academy of the University of Gothenburg and director of the institution's Centre for Antibiotic Resistance Research.
拉爾森是哥德堡大學薩爾格倫斯卡學院的一位教授，同時也是抗生素耐藥性研究中心的主任。The research did not state whether the bacteria were alive in the air, which would significantly increase the level of threat.
該研究並沒有說明這種將大大增加威脅水平的細菌是否還存活在空氣中。"It is reasonable to believe that there is a mixture of live and dead bacteria, based on experience from other studies of air," Larsson said.
拉爾森說道：“根據其他關於空氣的研究，我們有理由相信，空氣裏混有死的和活的細菌。”
