Time-to-positivity (TTP) of first positive blood cultures growing Gram-negative bacilli (GNB) was investigated. When anaerobic vials were positive first, TTP ≤ 18 h differentiated Enterobacteriaceae from strict anaerobic Gram-negative bacilli (PPV 98.8%). When the aerobic ones were first, TTP ≤ 13 h differentiated Enterobacteriaceae from Pseudomonas aeruginosa and other GNB (PPV 80.8%).
研究了首次阳性血培养革兰氏阴性杆菌（GNB）的阳性时间（TTP）。当厌氧瓶首先阳性时，TTP≤18 小时可区分肠杆菌科和严格厌氧革兰氏阴性杆菌（PPV98.8%）。当需氧瓶首先阳性时，TTP≤13 小时可区分肠杆菌科和铜绿假单胞菌及其他 GNB（PPV80.8%）。
