Fifty-four temporally and geographically distinct isolates of Haemophilus influenzae serotype a were characterized by (i) outer membrane protein composition and (ii) DNA polymorphism at the cap locus. In 53 of 54 cases, knowledge of the outer membrane protein type was accurately predictive of the cap locus polymorphism, suggesting that the majority of H. influenzae (type a) isolates have evolved from a limited number of clones.
对54株在时间和地理上均有差异的a型流感嗜血杆菌分离株进行了如下特征分析:(i)外膜蛋白组成,以及(ii)cap位点的DNA多态性。在54例中的53例中,外膜蛋白类型的信息能够准确预测cap位点的多态性,这表明大多数a型流感嗜血杆菌分离株是由数量有限的克隆株进化而来。
