title: Time-to-positivity-based discrimination between Enterobacteriaceae, Pseudomonas aeruginosa and strictly anaerobic Gram-negative bacilli in aerobic and anaerobic blood culture vials.
abstract: 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%).
