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.

三种生色介质分离囊性纤维化患者呼吸道样品中金黄色葡萄球菌的临床评价

与CNA培养基相比，我们评估了三种发色培养基（BBL CHROMagar™金黄色葡萄球菌，ChromID™金黄色葡萄球菌SAID，ChromID™ S.金黄色葡萄球菌精华SAIDE）在囊性纤维化患者呼吸道样品中分离金黄色葡萄球菌的性能。我们报道了四种培养基支持金黄色葡萄球菌生长的相似能力，并且当孵育持续超过24小时时敏感性增加。与其他培养基相比，SAIDE具有更高的灵敏度，即使在72小时后仍保持高特异性。
