The rapid identification of Staphylococcus aureus from positive blood cultures provides important clinical and therapeutic information. Using criteria based on direct Gram stain characteristics, an experienced microscopist was able to distinguish S aureus from other staphylococci isolated from BacT/ALERT blood culture bottles with an overall sensitivity of 89% and specificity of 98%. Furthermore, this method was readily taught to a clinical microbiologist who had not previously used the method first hand. Laboratories using the BacT/ALERT blood culture system should become familiar with these criteria so that S aureus bacteraemia can be identified rapidly.
从阳性血培养物中快速鉴定金黄色葡萄球菌可提供重要的临床和治疗信息。根据直接革兰氏染色特征制定标准，经验丰富的显微镜检查人员能够从BacT/ALERT血培养瓶中分离出的其他葡萄球菌中区分出金黄色葡萄球菌，总体灵敏度为89%，特异性为98%。此外，该方法很容易传授给一位此前未曾亲自使用过该方法的临床微生物学家。使用BacT/ALERT血培养系统的实验室应熟悉这些标准，以便能够快速鉴定金黄色葡萄球菌菌血症。
