BBC News -The first case of an infection that resists the antibiotic of last resort - colistin - has been detected in the US. The 48-year old woman from Pennsylvania recovered and the infection was vulnerable to other antibiotics.
BBC新闻 - 抵抗抗生素的最后防线 - 粘菌素 - 的首例感染在美国发现。宾州48岁的女病人已康复，感染对其它抗生素有反应。
However, colistin is hugely symbolic as it is used when other drugs fail and officials warned the world was now reaching "the end of the road" for antibiotics.
然而，粘菌素有巨大象征意义，因为它是在其它药物无效时才使用的，卫生官员警告，世界现正走向抗生素的"末路"。
Colistin resistance was first discovered in China at the end of 2015. The study sparked concern around the world, and intensive testing rapidly discovered bugs that can resist colistin in Europe and Asia.
粘菌素抵抗2015年末首次在中国发现。相关研究引发全世界的担忧，随后的密集试验迅速在欧洲和亚洲发现了能够抵抗粘菌素的细菌。
Now data from the US has identified the first case in a patient, who had a urinary-tract infection, as well as colistin-resistant bacteria in farm animals and meat on supermarket shelves.
现在，来自美国的数据显示，一名尿路感染病人身上出现首例粘菌素抵抗，农场牲畜和超市货架的肉类上也发现了对粘菌素产生耐药性的细菌。
It is not clear where the infection came from as the patient had not travelled recently and colistin is not widely used in the US.
尚不清楚感染从何而来，因为病人近期没有出行，且粘菌素在美国并未广泛使用。
The DNA that gives bacteria resistance to colistin - the mcr-1 gene - can spread rapidly between species. The concern is that colistin resistance will now hook-up with other forms of antibiotic resistance to create infections that cannot be treated.
使细菌对粘菌素产生耐药性的DNA - mcr-1基因 - 可在物种间迅速传播。令人担忧的是，粘菌素抵抗现在将会与其它形式的抗生素抵抗勾搭，造成无法医治的感染。
Thomas Frieden, the director of the Centers for Disease Control and Prevention, said: "The more we look at drug resistance, the more concerned we are…The medicine cabinet is empty for some patients, it is the end of the road for antibiotics unless we act urgently."
美国疾控中心主任弗利登说："我们对耐药性研究得越多，就越担忧……对某些病人，药箱已空,无药可用了, 抗生素走到了末路,除非我们紧急行动起来。"
However, Dr Beth Bell, also from the CDC, said in an interview: "Luckily haven't seen actual bacteria that are resistant to every single antibiotic."
但同样来自疾控中心的贝尔博士接受采访时说："幸运的是，还没有见过目前存在对每一种抗生素都有耐药性的细菌。"
