Abstract

Two hundred and fourteen strains of Coagulase negative Staphylococci (CNS) isolated from hospital personnel (114 strains) and patients (100 strains) were identified upto species level. The prevalence rate of CNS in relation to sex, sources and type of specimens were analysed. Most of the CNS strains belonged to S. epidermidis (49.1% among carriers and 39% in clinical isolates) and S. hominis (36% each). Besides, five more CNS species, namely S. saprophyticus, S. capitis, S. haemolyticus, S. cohnii and S. xylosus were also isolated. (0.5 to 10.3% isolation rates). Maximum S. hominis isolated were from hospital personnel and urine from patients (63.4% and 72.2%, respectively), 50.0% and 33.3% of S. hominis were found from urine and blood, respectively. The present study revealed that the leading species S. epidermidis and S. hominis may play an important role in the nosocomial infections, especially among immunocompromised hosts during their hospital stay.

摘要

对从医院工作人员（114株）和患者（100株）中分离出的214株凝固酶阴性葡萄球菌（CNS）进行了种水平鉴定。分析了CNS在性别、来源和标本类型方面的流行率。大多数CNS菌株属于表皮葡萄球菌（携带者中占49.1%，临床分离株中占39%）和人葡萄球菌（各占36%）。此外，还分离出另外5种CNS，即腐生葡萄球菌、头葡萄球菌、溶血葡萄球菌、科氏葡萄球菌和木糖葡萄球菌（分离率为0.5%至10.3%）。分离出的人葡萄球菌最多的分别来自医院工作人员和患者尿液（分别为63.4%和72.2%），分别有50.0%和33.3%的人葡萄球菌来自尿液和血液。本研究表明，主要菌种表皮葡萄球菌和人葡萄球菌可能在医院感染中起重要作用，尤其是在免疫功能低下宿主住院期间。
