Abstract

Five hundred and seven strains of bacteria isolated from the urine of patients with significant bacteriuria (more than 10(8) colony-forming units per litre) were tested for sensitivity to co-trimoxazole by the agar diffusion technique. Each organism was tested with a combined disk containing trimethoprim and sulphamethoxazole in a primary sensitivity test and, at a standardised inoculum, with both a combined disk and separate disks of trimethoprim and sulphamethoxazole. The results show that combined disk testing does not always indicate the sensitivity patterns of the organisms being tested.

摘要

采用琼脂扩散技术,对从有显著菌尿(每升超过10⁸菌落形成单位)患者尿液中分离出的507株细菌进行了复方新诺明敏感性检测。在初次敏感性试验中,每种微生物均用含有甲氧苄啶和磺胺甲恶唑的复合纸片进行检测,并在标准化接种量下,同时用复合纸片以及甲氧苄啶和磺胺甲恶唑的单独纸片进行检测。结果表明,复合纸片检测并不总是能显示被测微生物的敏感性模式。
