Abstract

The agar-slide blood culture system BCB Roche was compared with the Oxoid Signal blood culture system using 2,266 paired blood cultures. A total of 271 (12%) paired sets were culture-positive, including 222 (9.8%) yielding pathogens associated with septicemia and 50 (2.2%) yielding likely contaminants. In the recovery of the total 235 isolates considered as pathogens, the BCB Roche system yielded 202 (85.9%), the Oxoid Signal 211 (89.8%); 178 (75.7%) were cultured by both systems. There was no statistically significant difference between the two systems in their sensitivity, contamination-rate and detection time, except for gram-positive organisms, which were detected earlier by the Oxoid Signal system. Both systems performed well and were easy to handle.

摘要

使用2266对配对血培养，将罗氏琼脂玻片血培养系统（BCB Roche）与奥克托德信号血培养系统进行了比较。共有271对（12%）配对培养物呈培养阳性，其中222对（9.8%）培养出与败血症相关的病原体，50对（2.2%）培养出可能的污染物。在总共235株被视为病原体的分离株的回收率方面，罗氏BCB系统培养出202株（85.9%），奥克托德信号系统培养出211株（89.8%）；两种系统均培养出178株（75.7%）。除革兰氏阳性菌外，两种系统在敏感性、污染率和检测时间方面无统计学显著差异，奥克托德信号系统更早检测到革兰氏阳性菌。两种系统表现良好且易于操作。
