医院环境和医院感染病原菌的调查

本文结果表明:院内环境中细菌分布广泛,种类繁多。从院内环境及用具采取65份标本,分离出细菌38个种,共245株,革兰氏阳性球菌占51.8％(其中金黄色葡萄球菌占42.5％,凝固酶阴性葡萄球菌占44.1％),革兰氏阳性芽孢杆菌22.4％,革兰氏阴性杆菌占20.8％。对各科住院病人随机抽样调查667例,院内获得性感染47例,院内感染率7.0％。引起医院感染的病原菌主要是表皮葡萄球菌(20.0％),金黄色葡萄球菌(17.8％),大肠埃希氏菌(17.8％),克雷伯氏菌属(11.1％),非发酶菌(13.3％)。

Investigation of Pathogenic Bacteria of Hospital Environment and Hospital Infection

The paper result shows that bacteria were extensively dispersed in hospital with numerous cate- gories 65 samples were colected form the hospital envi- ronment and utensil and 38 species of bacteria 245 strains altogether were separated out. Cram-positive coccus was 51.8% (Staphylococcus aureus 42.5%, Coagulase-negative staphylococci 44. 1% among them), Gram-positive bacillus 22.4%, Gram-negative bacillus 20.8%, 667 cases were randomly sampled form among the inpatients of all departments, among them 47 cases were hospital-acquired infection, the in- fection rate was 7.0%. Main pathogenic bacteria which lead to hospital infection were Staphylococcus cpidermidis(20.0%), Staphylococcus aureus(17.8%), Esherichia coli(17.8%), Klebsiella(11.1%) and Nonfermenters.
