Abstract

We assessed the impact of the use of nasal swabs or nasopharyngeal aspirates and the time from specimen collection to storage at -70 degrees C on bacterial isolation. Haemophilus influenzae was isolated significantly less often from swabs than from nasopharyngeal aspirates. Samples in transit for >3 days were half as likely to grow Streptococcus pneumoniae and H. influenzae as those in transit for < or =3 days. There was no statistically significant difference for either Moraxella catarrhalis or Staphylococcus aureus.

摘要

我们评估了使用鼻拭子或鼻咽抽吸物以及从标本采集到在-70摄氏度下储存的时间对细菌分离的影响。从拭子中分离出流感嗜血杆菌的频率明显低于从鼻咽抽吸物中分离出的频率。运输超过3天的样本培养出肺炎链球菌和流感嗜血杆菌的可能性只有运输时间小于或等于3天的样本的一半。对于卡他莫拉菌或金黄色葡萄球菌,两者之间没有统计学上的显著差异。
