Nat Commun:荧光标记的万古霉素可实时观测细菌感染

2013-11-01 Nature中文网 Nature中文网

荧光标记的万古霉素(一种用来治疗细菌感染的抗生素)可被用来检测动物的细菌感染和人类尸体中与生物材料相关的感染。发表在本期Nature Communications上的这项研究,代表着用来检测可能是由以移植物形式存在的生物材料引起的细菌感染的一种灵敏的、具有特异性的和非入侵式的方法。 Marleen van Oosten、Gooitzen van Dam、Jan Maarten van Dijl和

荧光标记的万古霉素(一种用来治疗细菌感染的抗生素)可被用来检测动物的细菌感染和人类尸体中与生物材料相关的感染。发表在本期Nature Communications上的这项研究,代表着用来检测可能是由以移植物形式存在的生物材料引起的细菌感染的一种灵敏的、具有特异性的和非入侵式的方法。【原文下载】

Marleen van Oosten、Gooitzen van Dam、Jan Maarten van Dijl和同事给感染了金黄色葡萄球菌的小鼠注射了一剂荧光标记的万古霉素。这个剂量要比用于人类、能产生治疗反应的剂量低几倍。第二天,他们能够用一种非入侵式实时光学成像方法确定这些动物身上的细菌感染点。他们还在一个人类尸体上测试了这种检测方法,该尸体在人死后接受了被感染的移植物。他们发现,仅仅采用荧光抗生素,就足以检测到浅层移植的医疗设备上的细菌。作者报告说,该方法还允许对由细菌感染引起的炎症与非细菌炎症进行区分。

这一方法具有潜在重要性,因为与生物材料相关的感染构成一个重要的临床负担,而迄今为止还没有用来对患者的这些感染进行检测的灵敏的、具有特异性的和非入侵式的方法。
