Abstract
A prospective study was conducted to evaluate the radiometric detection of group D and viridans streptococci in blood, using three media preparations, Bactec 6A and 6B isotonic media and 8B hypertonic medium. All enterococci tested were detected by the 6A and 6B media. However, the 6A medium failed to detect 76% of the Streptococcus bovis isolates and 57% of the viridans streptococci, whereas all S. bovis isolates and 95% of the viridans streptococci were detected with the 6B formulation. No improvement in detection was noted in comparing the 6B and the 8B hypertonic media. The importance of adequate detection of this group of organisms, especially in patients with endocarditis, is discussed.
摘要
开展了一项前瞻性研究，以评估使用三种培养基制剂（Bactec 6A和6B等渗培养基以及8B高渗培养基）对血液中D群链球菌和草绿色链球菌进行放射性检测的情况。所有检测的肠球菌均能被6A和6B培养基检测到。然而，6A培养基未能检测出76%的牛链球菌分离株和57%的草绿色链球菌，而6B配方能够检测出所有牛链球菌分离株和95%的草绿色链球菌。比较6B和8B高渗培养基时，未发现检测效果有所改善。本文讨论了充分检测这类微生物的重要性，尤其是在心内膜炎患者中。
