Abstract
A study was performed with simulated blood cultures to evaluate the production of (14)CO(2) as an index of bacterial growth. With a range of inoculum sizes from 4 to 4,250 colony-forming units, it was not possible to detect (14)CO(2) within 6 hr after inoculation in 59 separate experiments. In a limited trial with patients' blood cultures, the radiometric method failed to provide any earlier evidence of bacteremia than did routine broth cultures.
摘要
进行了一项使用模拟血培养的研究，以评估作为细菌生长指标的（14）CO（2）的产生情况。接种量范围为4至4250个菌落形成单位，在59次独立实验中，接种后6小时内无法检测到（14）CO（2）。在一项针对患者血培养的有限试验中，与常规肉汤培养相比，放射测量法未能更早提供菌血症的证据。
