澳科学家找到杀灭超级细菌新方法

2018-03-07 新华网 新华网

澳大利亚阿德莱德大学6日宣布,该校研究人员找到了一种杀灭超级细菌的新方法,即通过改变铁供应使其变弱甚至死亡。超级细菌指对多种抗生素都有耐药性的细菌,由于病人感染超级细菌后缺乏有效治疗药物,有估计认为它们每年致死70万人。世界卫生组织预计,到2050年这一数字可能达1000万。因此,应对超级细菌成为医学界的紧迫任务。阿德莱德大学研究人员凯塔琳娜·里奇特在该校发布的新闻公报中说,她在研究中针对超级细菌

澳大利亚阿德莱德大学6日宣布,该校研究人员找到了一种杀灭超级细菌的新方法,即通过改变铁供应使其变弱甚至死亡。超级细菌指对多种抗生素都有耐药性的细菌,由于病人感染超级细菌后缺乏有效治疗药物,有估计认为它们每年致死70万人。世界卫生组织预计,到2050年这一数字可能达1000万。因此,应对超级细菌成为医学界的紧迫任务。

阿德莱德大学研究人员凯塔琳娜·里奇特在该校发布的新闻公报中说,她在研究中针对超级细菌的噬铁特性,改变超级细菌的铁供应,使它们丧失致病功能,最终死亡。

“铁对细菌而言就像是巧克力,带给细菌能量,让它们不断长大、致病,并能抵抗人类免疫系统和抗生素的攻击。”里奇特说,通过使用两种不同的化合物,我们先是让细菌缺铁,进而喂给它们对细菌而言有毒的物质,饥饿的细菌对这些有毒物质毫无抵抗力。

这种方法已经在动物实验中证明对金黄色葡萄球菌等超级细菌有效,下一步将运用到治疗鼻窦感染的人体试验中。两种化合物被包含在啫喱状物质中,可以只用于感染部位而无需全身施药。

里奇特表示,目前没有发现这种疗法有副作用,而且细菌在这种疗法下出现耐药性的风险也较低,因为细菌不大可能抗拒自己喜欢的食物。

对大肠杆菌(E.coli)的首次大规模遗传学研究表明,耐药“超级细菌”并不总是与其他菌株竞争,大肠杆菌来自英国血液感染患者。 Wellcome Trust Sanger研究所及其合作者的研究表明,新型大肠杆菌经常出现,但与其他一些感染不同,耐药菌株并不是感染的主要原因。

mBio:医院废水中存在的“超级细菌”,可能是多种疾病久治不愈的祸根

一项新的研究表明,医院废水系统可能起到抗生素耐药性的作用。

ACS Chem Biol:来自蜘蛛的新肽类可有效对抗超级细菌及癌症!

随着抗生素耐药性的上升和对超级细菌的担忧增加,科学家们正在寻找新的治疗方案。一个重点领域是抗菌肽(AMP),它们有可能成为当前处方抗生素的替代品,其中许多抗生素对一些细菌越来越无用。现在,一个团队报告ACS化学生物学,他们已经提高了AMP的抗菌和抗癌性能。

SCI REP:制服“超级细菌”抗药性的妙药,竟寻自动物粪便

一类能专门杀死细菌的病毒——噬菌体,将来也许有一天会解决日益增长的超级细菌”感染问题。最近,贝勒医学院(BCM)等机构的科学家们发现,噬菌体可以有效地减少小鼠体内的细菌水平,包括对多种抗生素抗性的“超级细菌”,从而显著改善小鼠的健康。这一结果发表在《自然》子刊《Scientific Reports》上。

当心无药可医 警惕滥用抗菌药物致超级细菌

记者从长沙市中心医院了解到,近日,医院收治的16岁少年王帅(化名)被诊断为超级细菌MRSA感染,双肺出现多个空洞,在呼吸疾病加强监护病房抢救15天后,脱离了生命危险。
