To achieve faster bacteremia diagnosis, selected ion flow tube mass spectrometry (SIFT-MS) measured metabolic gases in the headspaces of BacT/ALERT blood culture bottles. Pseudomonas aeruginosa, Streptococcus pneumoniae, Escherichia coli, Staphylococcus aureus and Neisseria meningitidis growth and trace gas patterns were detected from 10 colony forming units after 6 h.
为实现更快的菌血症诊断，采用选择离子流管质谱法（SIFT-MS）测量BacT/ALERT血培养瓶顶部空间中的代谢气体。6小时后，从10个菌落形成单位中检测到铜绿假单胞菌、肺炎链球菌、大肠杆菌、金黄色葡萄球菌和脑膜炎奈瑟菌的生长及痕量气体模式。
