Abstract

We evaluated the performance of three chromogenic media (BBL CHROMagar™ Staph aureus, ChromID™ S. aureus SAID, ChromID™ S. aureus Elite SAIDE) for the isolation of Staphylococcus aureus in respiratory samples in patients with cystic fibrosis in comparison with CNA media. We reported a similar ability of the four media to support the growth of S. aureus and that sensitivity increased when incubation lasted more than 24 h. SAIDE had the higher sensitivity compared to the other media and kept a high specificity even after 72 h.

摘要

我们评估了三种显色培养基（BBL CHROMagar™金黄色葡萄球菌、ChromID™金黄色葡萄球菌 SAID、ChromID™金黄色葡萄球菌 Elite SAIDE）在与 CNA 培养基比较时，用于分离囊性纤维化患者呼吸道样本中的金黄色葡萄球菌的性能。我们报告称，这四种培养基支持金黄色葡萄球菌生长的能力相似，并且当孵育时间超过 24 小时时，敏感性会增加。SAIDE 比其他培养基具有更高的敏感性，即使在 72 小时后仍保持较高的特异性。
