Abstract

Randomly amplified polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE) for the analysis of 13 Moraxella catarrhalis isolates, 11 successive strains isolated from sputa of five children and 2 isolates obtained the same day from twins, were compared. RAPD and PFGE both yielded nine types from the 13 isolates, showing a chronic colonization with one strain in three patients and a successive colonization with different strains in two patients. The promising results obtained with RAPD should be confirmed with a larger number of strains, but RAPD seems as suitable as PFGE for the typing of M. catarrhalis.

摘要

比较了随机扩增多态性DNA(RAPD)和脉冲场凝胶电泳(PFGE)对13株卡他莫拉菌分离株的分析结果,其中11株连续菌株来自5名儿童的痰液,2株分离自同一天的双胞胎。RAPD和PFGE均从13株分离株中产生了9种类型,显示3名患者中有一种菌株的慢性定植,2名患者中有不同菌株的连续定植。用RAPD获得的有前景的结果应通过更多菌株进行验证,但RAPD似乎与PFGE一样适用于卡他莫拉菌的分型。
