研究发明：蓝光可有用削弱超等细菌MRSA

宣布时间：2019-04-08作者：LEDinside LED在线

抗生素是20世纪最主要的科学发明之一，，，，，，但其有用性正在迅速消退。。。。。。太过使用导致细菌对药物爆发耐药性，，，，，，这可能会使我们走向一个一经简朴的熏染再次危及生命的未来。。。。。。现在，，，，，，普渡大学的研究职员发明蓝光可以削弱一种特殊令人厌恶的“ 超等细菌 ”，，，，，，并使其再次受到温吮厩剂的影响。。。。。。

金黄色葡萄球菌(Staphylococcus aureus)是一种常见的细菌，，，，，，大部分都是无害的，，，，，，但某些菌株会引起更多问题。。。。。。耐甲氧西林金黄色葡萄球菌(MRSA)是一种特殊贫困的细菌，，，，，，对免疫系统已经受损的人来说是最危险的，，，，，，这意味着它可能在医院和养老院中造成严重熏染。。。。。。不幸的是，，，，，，这已经变得越来越难以治疗 - 它不但仅是对甲氧西林爆发耐药性，，，，，，并且对越来越多的其他常见抗生素也爆发耐药性。。。。。。

新的抗生素现在仍在开发中，，，，，，但虽然最终细菌也不可阻止地会爆发耐药性。。。。。。因此，，，，，，科学家们正在起劲寻找超等细菌无法顺应的恒久解决计划，，，，，，例如能快速祛除细菌的抗菌质料或可释放活性氧以杀灭超等细菌的光敏型纳米颗粒。。。。。。

同样，，，，，，普渡大学的研究职员开发了自己的光疗法。。。。。。研究小组发明，，，，，，MRSA可以通过“光漂白”来削弱 - 通过将细菌袒露在蓝光下，，，，，，从基础上消除了细菌的颜色。。。。。。由于这些色素是细菌怎样熏染宿主的一部分，，，，，，这可能会降低它们造成危险的能力。。。。。。

“当你在洗衣机中漂白某些工具时，，，，，，你会使用化学物质往复除颜色，，，，，，”该研究的作者Mohamed Seleem说道。。。。。。“我们在这里做的很相似，，，，，，但我们正在使用蓝光。。。。。。”

光自己并没有杀死MRSA - 相反，，，，，，它降低了它的防御能力，，，，，，足以使药物和其他分子完成它，，，，，，纵然那些细菌通�；；；；；；；；岫钥顾�。。。。。。在对MRSA熏染伤口的小鼠举行的测试中，，，，，，研究职员发明，，，，，，像过氧化氢这样的温吮厩剂可以有用地破损被蓝光削弱的细菌。。。。。。

该团队已获得专利，，，，，，该装备使用该手艺治疗MRSA熏染的伤口。。。。。。这个想法是，，，，，，它将接纳一个带有灯的小盒子的形状，，，，，，通过一个洞照射到伤口上。。。。。。主要的是，，，，，，科学家已经发明光在哺乳动物细胞上是清静的。。。。。。

“这种新工具可以治疗熏染MRSA的任何外貌伤口，，，，，，这些伤口通常很难治疗，，，，，，”Seleem说道。。。。。。“该装备自己很是小巧，，，，，，易于使用。。。。。。我们希望在未来几年内，，，，，，任何人都可以随身携带它。。。。。。”

该研究揭晓在《Advanced Science》杂志上。。。。。。
