Abstract

We studied the ability of normal human serum to lyse H. influenzae biogroup aegyptius (H. aegyptius) isolates recovered from patients with Brazilian purpuric fever (BPF clone) or non-BPF clone strains. BPF clone isolates, although similar to non-BPF clone isolates with regard to the ability to fix C3 to their surfaces, could be distinguished from non-BPF clone strains by their resistance to lysis in vitro following incubation with normal adult human serum.

摘要

我们研究了正常人血清对从巴西紫癜热患者中分离出的埃及嗜血杆菌生物群(埃及嗜血杆菌)分离株(BPF克隆株)或非BPF克隆株菌株的裂解能力。BPF克隆株分离株虽然在将C3固定到其表面的能力方面与非BPF克隆株分离株相似,但通过与正常成人血清孵育后对体外裂解的抗性,可与非BPF克隆株菌株区分开来。
