Abstract
For the optimal recovery of from the BACTEC™ Mycobacterium Growth Indicator Tube 960™ system, an incubation period of 42-56 days is recommended by the manufacturer. Due to logistical reasons, it is common practice to follow an incubation period of 42 days. We undertook a retrospective study to document positive Mycobacterium Growth Indicator Tube cultures beyond the 42-day incubation period. In total, 98/110 (89%) were positive for complex. This alerted us to growth detection failure at 42 days.
摘要
为了从BACTEC™ 960分枝杆菌生长指示管系统中实现最佳恢复，制造商建议培养期为42至56天。由于后勤原因，通常采用42天的培养期。我们进行了一项回顾性研究，以记录培养期超过42天的分枝杆菌生长指示管培养阳性情况。总共98/110（89%）的培养物对复合菌呈阳性。这提醒我们在42天时存在生长检测失败的情况。
