Abstract

Six rapid agglutination tests for the identification of Staphylococcus aureus were evaluated by testing 416 strains of staphylococci. The sensitivities and specificities of the tests were as follows: Staphyloslide, 97.7% and 99.3% respectively; Prolex Staph Latex, 96.9% and 93.6%; Staphaurex, 95.4% and 94.2%; Staphaurex Plus, 100% and 93.4%; Slidex Staph Plus, 98.9% and 99.3%; and Staphytect Plus, 99.6% and 88.2%. The three tests utilizing latex particles coated with staphylococcal capsular antibodies were better able to identify methicillin-resistant S. aureus, but only Staphyloslide and Slidex Staph Plus had adequate specificity.

摘要

通过对416株葡萄球菌进行检测，评估了六种用于鉴定金黄色葡萄球菌的快速凝集试验。这些试验的敏感性和特异性如下：葡萄球菌玻片凝集试验（Staphyloslide）分别为97.7%和99.3%；Prolex葡萄球菌乳胶凝集试验（Prolex Staph Latex）为96.9%和93.6%；金黄色葡萄球菌快速诊断试剂（Staphaurex）为95.4%和94.2%；增强型金黄色葡萄球菌快速诊断试剂（Staphaurex Plus）为100%和93.4%；葡萄球菌玻片凝集试验升级版（Slidex Staph Plus）为98.9%和99.3%；葡萄球菌检测试剂升级版（Staphytect Plus）为99.6%和88.2%。三种使用包被葡萄球菌荚膜抗体乳胶颗粒的试验在鉴定耐甲氧西林金黄色葡萄球菌方面表现更佳，但只有葡萄球菌玻片凝集试验和葡萄球菌玻片凝集试验升级版具有足够的特异性。
