Abstract

A comparison between direct and standardized disk diffusion tests was made on a total of 300 urine specimens containing >/=10(5) organisms/ml. Of these, 246 represented pure cultures and 54 represented mixed cultures. The number of major discrepancies per organism tested in pure culture was 18 (7.3%) and in mixed cultures it was 23 (42.6%). The percentage of major discrepancies per total number of antimicrobial drug comparisons made was 1.4%. Although this procedure may be of value in selected cases with pure cultures of organisms present in quantities >/=10(5)/ml, its use on a routine basis is not recommended.

摘要

对总共300份每毫升含有≥10⁵个微生物的尿液标本进行了直接平板扩散试验和标准化平板扩散试验的比较。其中,246份为纯培养物,54份为混合培养物。在纯培养物中,每种测试微生物的主要差异数量为18(7.3%),在混合培养物中为23(42.6%)。抗菌药物比较总数中的主要差异百分比为1.4%。尽管该方法在某些每毫升含有≥10⁵个微生物的纯培养物的特定病例中可能有价值,但不建议常规使用。
