A single bottle blood culture system (Oxoid Signal system) was compared with a conventional two bottle subculturing system. A total of 2016 routine blood samples yielded 186 (9%) clinically important isolates. Of these, 40 (21%) were isolated only in the Oxoid system and 30 (17%) only in the conventional system. One hundred and sixteen (62%) were isolated from both systems. Volume of blood was not significantly associated with the rate of detection but was significantly associated with the speed of detection. A continuation of the study with a Signal bottle and single conventional bottle confirmed initial results of the increased isolation rate using two systems. The Oxoid single bottle blood culture system was at least comparable with a conventional system in terms of rate of detection of organisms and was superior in terms of speed of detection.
将一种单瓶血培养系统（Oxoid信号系统）与传统的两瓶传代培养系统进行了比较。总共2016份常规血样培养出186株（9%）具有临床意义的分离菌。其中，40株（21%）仅在Oxoid系统中分离得到，30株（17%）仅在传统系统中分离得到。116株（62%）在两种系统中均能分离得到。血样体积与检出率无显著相关性，但与检出速度显著相关。使用信号瓶和单个传统瓶继续进行的研究证实了使用两种系统提高分离率的初步结果。Oxoid单瓶血培养系统在微生物检出率方面至少与传统系统相当，在检出速度方面更具优势。
