摘要 目的对比BacT/ALERT和伯泰血培养瓶对模拟菌血症标本的检测能力。方法将已知待检细菌配制成100和10CFU/ml两个菌液浓度的模拟菌血症标本,加入BacT/ALERT和伯泰血培养瓶,装载于BacT/ALERT3D120快速血液培养仪,比较需氧瓶对需氧菌、厌氧瓶对厌氧菌和兼性厌氧菌的阳性率和平均检测时间。结果两种需氧瓶对需氧菌检测的阳性率均为100%,100和10CFU/ml两个菌液浓度的平均检测时间,BacT/ALERT需氧瓶分别为19.0±5.2h和22.6±6.2h,伯泰需氧菌分别为20.2±4.4h和23.5士6.1h,两者差异无统计学意义0=1.219,0.709,P〉0.05);两种厌氧瓶对兼性厌氧菌检测的阳性率均为100%,100和10CFU/ml两个菌液浓度的平均检测时间,BacT/ALERT厌氧瓶分别为13.7±4.1h和17.8士5.4h,伯泰厌氧瓶分别为17.7±8.0h和22.6±10.8h,两者差异无统计学意义(t=0.387,0.426,P〉0.05);对专性厌氧菌,BacT/ALERT和伯泰厌氧瓶100CFU/ml菌液浓度检测的阳性率均为100%,平均检测时间分别为36.9±3.0h和70.4±14.9h,两者差异有统计学意义0—4.856,P〈0.05);10CFU/ml菌液浓度的阳性检测率分别为100%和33.3%,BacT/ALERT厌氧瓶的平均检测时间为59.5±19.9h,伯泰厌氧瓶三株细菌中有两株未能得到阳性结果。结论使用Bact/ALERT3D120快速血液培养仪,对于怀疑需氧菌或兼性厌氧菌感染,可以选用BacT/ALERT或伯泰需氧瓶,对于怀疑厌氧菌感染,应当选用BacT/ALERT厌氧瓶。
