益生菌作为一种“好”细菌被卖给咱们,它能协助咱们平衡肠道中各种“坏”微生物。但在老garage鼠身上的一项新试验标明,咱们的微生物盟友是怎么进化成可能对咱们的肠道形成危害的背叛者的。

Probiotics are sold to us as 'good' bacteria that help balance out 'bad' varieties of microbes camping out in our gut. But a new experiment on mice has shown how our microbial allies can evolve into traitorous backstabbers that risk causing damage to our guts.

病理学家兼生物医学工程师Gautam Dantas说:“假如咱们要把生物作为药物来运用,咱们需求认识到它们会适应环境,这意味着救心菜在体内呆了几个小时的东西不一定和你放入身体的东西是一个。”

"If we'曾国藩家书re going to use living things as medicines, we need to recognise that they're going to adapt, and that mea千王之王,你还在喝酸奶摄生吗?新研讨告诉你,益生菌喝错了有害无利!,大公报ns that what you put in your body is not necessarily what's going to be there even a couple 五脏hours later," says pathologist and biomedical engineer Gautam Dantas.

“没有一种微生物对进化免疫。”

"There is no microbe out there that is immune to evolution."

Dantas led a team of researchers from the University of Washington who evaluated a bacterium marketed to help combat diarrhoea: EcN.

为了评价EcN被吞食后的进化潜力,研讨小组运用了彻底无菌的特别培养小鼠。商务英语

试验目标被分红四组,每组都有一个共同的肠道微生物群。一个彻底无菌;别的三组给予反映各种再生人陈明道是假的健康和不健康状况的微生物群落。

每沦为一组都被给予EcN,然后喂养以下选项之一——庸俗的一般试验鼠粮,更天然的老鼠友爱型饮食,高脂肪和高糖的西式饮食,以及添加了一些纤维的西式饮食。

五周后,查看了老鼠的肠道。仍是那些高兴的小大肠杆嗨文菌?事实证明,它们并不都像刚来的时分那么友爱,尤其是那些处于不得不应对不健康的饮食的肠道里的。
