A prospective study was conducted on 25 Legionella pneumophila culture-positive and 98 culture-negative bronchoalveolar lavage fluid samples to compare two DNA preparation methods: a rapid modified Chelex-based protocol and a proteinase K method. PCR was found to be more sensitive with the Chelex-based method (P = 0.03). N difference was found concerning the inhibition rate.
对25份嗜肺军团菌培养阳性和98份培养阴性的支气管肺泡灌洗液样本进行了一项前瞻性研究,以比较两种DNA制备方法:一种基于改良Chelex的快速方案和一种蛋白酶K方法。发现基于Chelex的方法进行PCR检测时更敏感(P = 0.03)。在抑制率方面未发现差异。
