文摘大家译:爆发后抗新糖肽类抗生素肠球菌流行与非流行株的区分

Discrimination between epidemic and non-epidemic glycopeptide-resistant E. faecium in a post-outbreak situationJournal of Hospital Infection
Volume 67, Issue 1, September 2007, Pages 49-55

Summary
Vancomycin-resistant enterococci (VRE) have been isolated in increasing numbers. Hospital-adapted VRE exhibit relatively high pathogenicity by expressing factors like enterococcal surface protein (Esp), which facilitates epidemic spread. By contrast, ‘community-acquired’ VRE show low pathogenicity and non-epidemic features. In 2004 and 2005 an extended outbreak of VRE occurred at a university hospital in Southwestern Germany and an infection control programme was implemented to confine the outbreak. Pulsed-field gel electrophoresis (PFGE), esp PCR, multiple-locus variable number of tandem repeat analysis (MLVA), purK1 typing and multiple-locus sequence typing (MLST) were performed on representative VRE isolates. Twenty-six non-epidemic and two epidemic VRE types (MLST203, MLST280) were identified by PFGE. Seven of the non-outbreak VRE types were esp gene negative, whereas 19 non-outbreak and both epidemic VRE types were esp positive. Eight MLVA types were identified. MLVA type 1 included five PFGE types and MLVA type 159 included 16 PFGE types. Currently there is no efficient method available to identify non-epidemic VRE and avoid unnecessary isolation of patients. More than 50% non-epidemic clones were esp positive; nevertheless, esp PCR appears to be the most promising approach to identify non-epidemic VRE.

iscrimination between epidemic and non-epidemic glycopeptide-resistant E. faecium in a post-outbreak situation(暴发感染后耐糖肽类抗生素屎肠球菌流行株与非流行株的鉴别)
Summary
Vancomycin-resistant enterococci (VRE) have been isolated in increasing numbers. (总结:目前,临床上耐万古霉素肠球菌的分离率正在不断增加。)Hospital-adapted VRE exhibit relatively high pathogenicity by expressing factors like enterococcal surface protein (Esp), which facilitates epidemic spread. (适应医院环境特点的或称作医院适应性的VRE致病力相对较高,这种类型的VRE通过表达一些因子如肠球菌表面蛋白Esp使得其传播扩散变得更加容易。)By contrast, ‘community-acquired’ VRE show low pathogenicity and non-epidemic features. (相反,社区获得性的VRE却表现出低致病力和非流行性的特点。)In 2004 and 2005 an extended outbreak of VRE occurred at a university hospital in Southwestern Germany and an infection control programme was implemented to confine the outbreak. (在2004至2005年,在德国西南部的一家大学教学医院发生过一起波及范围很大的VRE暴发,相关感控措施随后跟进并成功控制了这次暴发流行。)Pulsed-field gel electrophoresis (PFGE), esp PCR, multiple-locus variable number of tandem repeat analysis (MLVA), purK1 typing and multiple-locus sequence typing (MLST) were performed on representative VRE isolates.(对有代表性的VRE分离株进行脉冲肠凝胶电泳分型,PCR寻找esp基因的有无,可变数目串联重复序列分析MLVA,purK1分型,以及多重位点 序列分型MLST。) Twenty-six non-epidemic and two epidemic VRE types (MLST203, MLST280) were identified by PFGE. (通过PFGE共找到26个非流行型和2个流行型MLST203, MLST280。)Seven of the non-outbreak VRE types were esp gene negative, whereas 19 non-outbreak and both epidemic VRE types were esp positive. (其中,7个非流行株esp基因阴性,而19个非流行株和所有的流行株都是eap基因阳性。)Eight MLVA types were identified. MLVA type 1 included five PFGE types and MLVA type 159 included 16 PFGE types. (用MLVA一共分出8个亚型,MLVA亚型1包括了5个PFGE亚型,MLVA亚型159包括了16个PFGE亚型。)Currently there is no efficient method available to identify non-epidemic VRE and avoid unnecessary isolation of patients. (目前,还没有有效的办法来鉴别非流行型VRE,也无法避免不必要的病人隔离措施。)More than 50% non-epidemic clones were esp positive; nevertheless, esp PCR appears to be the most promising approach to identify non-epidemic VRE. (超过50%的非流行型的VRE是esp阳性,不过,用PCR寻找esp基因似乎仍然是鉴别非流行型VRE最值得期待的方法。):ok :haha

的专业英语不错!搞医学微生物学的吧?研究生?
能自我介绍一下吗?也让大家认识认识您这位胡教授的高徒!:handshake :ketou

以把你的译文给整理一下吗?这样更便于网友们浏览.
谢谢!

呵,多谢夸奖哦。我现在威尔士亲王医院微生物系读研。巴版是微生物前辈了。以后还请多多关照啊。:$ :handshake

尔士亲王医院是香港非常出名的一家医院,微生物学属于纯欧洲血统,正宗!
好好干!戒骄戒躁,塌实的“做学问”!将来的大专家就出在你们这些天之娇子当中。

现时约有1360张病床及近4000名员工
哇噻,员工配备超豪华!科研人员很多吗?:o

有欧洲血统的说法阿,我在这里都不知道呀,原来微生物学还分血统阿,只不过这里的教授基本上都从英国学好回来的。

难怪这么厉害!:ketou

就不知道了吧!在微生物学的很多问题上激进和投机的老美和咱们严谨却保守的老英一直就存在较大的分歧,甚至互相不买帐哦!
比如就药敏规则来说吧,欧洲惯用BSAC的标准,而美洲及世界上大多数的国家还是推崇CLSI标准.
咱们司徒教授和凌建华教授在早些年的时候就爱提,我们的微生物学是来自正宗的微生物学的发祥地----欧洲,和美洲的微生物学会属于不同的派系.
但近年来,不怎么听到这样的说法了,可能是香港回归了,世界的政治格局也发生变化了吧!

有这么多学问,有时间套套老板的 话,嘻嘻
