Abstract

The present study was undertaken to investigate the frequency of the nasal carrier rate of Staphylococcus aureus. The investigation was performed on 104 healthy persons. The total number of swabs performed was 1498 and this resulted in isolation of 522 S. aureus strains. All strains have been identified, tested for antibiotic susceptibility, and phage-typed. The carrier-index (number of positive swabs/number of total swabs for each individual person) was compared with different sampling and culturing methods, phage type, age, and resistance to antibiotics. There was statistical difference in carrier rate according to sex (P < 0.05). Among the 104 persons 15 (14.4%) were persistent carriers, 17 (16.3%) intermittent carriers, 55 (52.9%) occasional carriers and 17 (16.3%) non-carriers. Among intermittent and occasional carriers the phage-type distribution was different from the S. aureus strains isolated from Danish hospitalized patients in 1992, while the persistent carriers had similar phage-type distribution.

摘要

本研究旨在调查金黄色葡萄球菌鼻腔携带率。对104名健康人进行了调查。共采集拭子1498份,分离出522株金黄色葡萄球菌菌株。所有菌株均已鉴定、进行了药敏试验并进行了噬菌体分型。将携带指数(每个人的阳性拭子数/总拭子数)与不同的采样和培养方法、噬菌体类型、年龄以及抗生素耐药性进行了比较。根据性别,携带率存在统计学差异(P < 0.05)。在这104人中,15人(14.4%)为持续携带者,17人(16.3%)为间歇性携带者,55人(52.9%)为偶尔携带者,17人(16.3%)为非携带者。在间歇性和偶尔携带者中,噬菌体类型分布与1992年从丹麦住院患者中分离出的金黄色葡萄球菌菌株不同,而持续携带者的噬菌体类型分布相似。
