Nature:晕,超级细菌克星!就藏在我们的鼻腔

2016-07-28 MedSci MedSci原创

“住”在我们鼻腔中的一种细菌可生产出能杀死超级细菌的新药。德国图宾根大学的一个研究小组称,他们在人类鼻腔内发现的一种名为“路邓葡萄球菌”的细菌,具有独特功效,在被制成抗生素后不但能杀灭超级细菌,还不易产生耐药性。该发现有助研发出新型疗法,让此前“刀枪不入”的超级细菌闻风丧胆。 抗生素曾被称为抗菌素,在大量使用多年后,也让细菌产生了极强的抗药性。以耐甲氧西林金黄色葡萄球菌(MRSA)、抗万古霉

“住”在我们鼻腔中的一种细菌可生产出能杀死超级细菌的新药。德国图宾根大学的一个研究小组称,他们在人类鼻腔内发现的一种名为“路邓葡萄球菌”的细菌,具有独特功效,在被制成抗生素后不但能杀灭超级细菌,还不易产生耐药性。该发现有助研发出新型疗法,让此前“刀枪不入”的超级细菌闻风丧胆。 抗生素曾被称为抗菌素,在大量使用多年后,也让细菌产生了极强的抗药性。以耐甲氧西林金黄色葡萄球菌(MRSA)、抗万古霉素肠球菌(VRE)等为代表的超级细菌开始逐渐嚣张。面对这种病菌,普通杀菌药物毫无作用,人类几乎陷入了无药可用的窘境。 大部分抗生素取自土壤活菌,但就像开采过度的矿山一样,如今要在那里发现新的抗生素越来越难。科学家们不得不将目光转向包括人体在内的动植物。人体内存在着各种微生物,鼻腔也不例外。科学家发现,不少人鼻腔中存在着金黄色葡萄球菌,但真正致病的却并不多,这一现象一直让科学家疑惑不解。 德国图宾根大学的安德烈亚斯·佩舍尔和他的同事发表在最新一期《自然》杂志上的论文称,在新的研究中,他们用在鼻腔中发现的路邓葡萄球菌(Staphylococcus lugdunensis)产生出了一种名为“路邓素(

“超级细菌”现身美国,去年在中国首先发现! 可抵抗已知所有抗生素

据外媒报道,美国卫生官员26日报告称,美国发现首例对所有已知抗生素有抵抗力的细菌感染病例,如果这种超级细菌传播,可能造成日常感染的严重危险。 “我们有身处后抗生素世界的风险。”美国疾病控制和预防中心(CDC)主任弗里登(Tom Frieden)指的是宾夕法尼亚州一名49岁女性的尿路感染病例,这名女性在之前的五个月内没有外出旅行史。 弗里登在美国国家记者俱乐部午餐会上讲话时称,就连粘杆菌素(

随着“超级细菌”的不断出现,规范抗菌药物临床应用行为、遏制细菌耐药发展,始终是卫计委近年来的工作重点。

“超级细菌”MRSA的克星来了 存在南极海绵中

近日,研究者在一种南极海绵动物中发现了一种物质,该物质可以有效杀灭98%的耐药超级菌——耐甲氧西林金黄色葡萄球菌(methicillin-resistant Staphylococcus aureus,MRSA),目前该菌在美国快速传播。随着越来越多的细菌对目前使用的抗生素产生耐药性,科学家正在极力地寻找可以抵御这些病菌的物质,这 项研究发现的存在于南极海绵中的一种物质可能是其中的一个选择。

“超级细菌”的耐药性基因可遗传

6月22日, 德国科学家日前发布的一项研究成果显示,让细菌具有耐药性的基因不仅能够跨越不同物种传播,还能通过接触染色体而遗传。 以某些大肠杆菌为代表的革兰氏阴性菌已对多种抗生素具有耐药性。目前,多粘菌素是对抗耐药性细菌的最后一道防线,但是一个名为MCR-1的基因会让细菌对多粘菌素也产生耐药性,变成“超级细菌”,使相关疾病的治疗更加困难。 2015年11月,中国首次报告在牲畜和人身上

可耐强抗生素的“超级细菌”,在美国再次现身!

美国研究人员11日说,美国发现第二例携带含基因MCR-1的“超级细菌”病例(首例是5月份报道:美国发现首例mcr-1多粘菌素耐药感染)(“超级细菌”现身美国,去年在中国首先发现! 可抵抗已知所有抗生素)。这个基因会使细菌对被称为抗生素中“最后一道防线”的多粘菌素产生耐药性。美国JMI实验室的研究人员在新一期美国《抗微生物制剂与化学疗法》期刊上报告说,在源于纽约一名患者的大肠杆菌中发现了MCR-1基

超级细菌的耐药性怎么解决?

抗生素耐药性正成为世界民众面临的主要问题和严峻挑战。CDC数据显示,美国每年约有200万人出现耐药性感染,超过23000人死于耐药性感染。 抗碳青霉烯类肠杆菌属(CRE)是一些耐药比较严重的细菌,菌种包括大肠杆菌、肺炎克雷伯杆菌等,单从菌种来看(不考虑耐药性的话)它们都是人肠道中的常见细菌。CRE已经成为美国耐药性感染的最大威胁之一,每年约9000人出现CRE耐药性感染,其中600人死亡。CRE几
