我院10个病室的医务人员和部分病人金黄色葡萄球菌的鼻腔总带菌率为32.87％;与入学新生带菌率16％相比,差别有高度显著性。医院内金黄色葡萄球菌449株,用伦敦中央公共卫生实验室提供的23林基础分型噬菌体进行分型,查出流行性感染两起;局限型交叉感染四起,其中一起由新型菌株S_(18042)/W_(57)/S_(1030)所引起。对医院内感染的控制方法进行了探讨。
The total nasal bacterial load of medical staff of 10 wards and some patients of Staphylococcus aureus in our hospital was 32.87%. Compared with 16% of freshmen admitted to school, the difference was highly significant. 449 strains of Staphylococcus aureus in the hospital were genotyped by 23 Lin-based genotyping bacteriophages provided by the Central Public Health Laboratory in London, and two were identified as epidemic infections. Four were found to be localized and cross-infected. Four of them were identified by a novel strain S_ (18042 ) / W_ (57) / S_ (1030). The control methods of nosocomial infection were discussed.
