The rates of recovery of bacteria from vented vacuum blood culture bottles containing 50 and 100 ml of a soybean-casein digest broth were compared. Overall, more isolates were recovered from the larger bottle; moreover, gram-negative bacilli and especially Pseudomonas aeruginosa were recovered significantly more frequently (P less than 0.01) from the 100-ml bottle.
对含有50毫升和100毫升大豆酪蛋白消化肉汤的通气真空血培养瓶中细菌的回收率进行了比较。总体而言,从较大的培养瓶中回收的分离株更多;此外,革兰氏阴性杆菌,尤其是铜绿假单胞菌,从100毫升培养瓶中回收的频率显著更高(P<0.01)。
