Methicillin-resistant Staphylococcus aureus(MRSA)has become a common cause of nosocomial infection globally,particularly in the Intensive Care Unit(ICU).In this study,we report an outbreak of MRSA in a Neurosurgical Intensive Care Unit(NICU)in China involving 20 bacterial isolates.

目的 细菌感染是临床常见的疾病.在一些细菌感染疾病如关节炎和脑膜炎中,虽使用越来越高级的抗生素,但疾病的后遗症仍然很严重,其原因仍不清楚.细菌DNA是细菌的遗传物质,但近十几年来,研究发现细菌DNA具有免疫原性.为了明确细菌DNA是否具有病原性,我们做了如下的研究.方法 直接关节腔内和脑室内注射细菌DNA和CpGDNA,用组织病理学方法评价细菌DNA是否能够引起关节炎和脑膜炎,并进一步研究其发病机
目的 分析不同基因型金黄色葡萄球菌临床分离株体外侵袭能力的差异,为进一步阐明金黄色葡萄球菌致病机制及防控其医院内感染提供新的实验数据;方法 采用脉冲场凝胶电泳方法(PFGE)对43株金黄色葡萄球菌临床分离株进行分子分型,抗生素保护实验和流式细胞内化实验检测不同基因型金黄色葡萄球菌体外侵袭能力;结果 按照80%相似度为计算依据,43株金黄色葡萄球菌共分12个PFGE基因型,2个优势型(Ⅰ和Ⅱ型)分别
目的 布氏菌(Brucella)是一个重要的人兽共患病病原菌,该菌侵入人或动物后可引起人兽共患的传染一变态反应性疾病,即布氏菌病(Brucellosis,简称布病),是我国规定报告的乙类传染病.我国自21世纪以来,布氏菌病患者数量逐步增加,加强布鲁氏病的防治成为了我国医疗系统当前的重要任务.布氏菌菌型的鉴别对于布氏菌病的预防和最终消灭布氏菌病具有关键性的作用,目前的分型方法主要有表型分型和基因分型
