比曼教授这次来华讲学的主题是传染病在分子生物学和细胞生物学方面的新进展,共分十五个专题,概括为四方面内容,即:(1)对病原菌超微结构上的新认识;(2)专性或兼性胞内寄生菌与宿主的相互作用,(3)宿主淋巴细胞亚群及淋巴因子在抗感染免疫中的作用;(4)研究寄生菌与宿主相互作用的新方法。现整理如下: 一、关于细菌的超微结构观察细菌的鞭毛是由鞭毛蛋白组成的细丝、弯曲呈钩状的钩鞘和基粒三部分组成。基粒是由四个环形结构固定在细菌的胞浆膜和细胞壁上。钩鞘和基粒是鞭毛运动时的枢钮。革兰氏阴性杆菌的表面还存在有短而直的菌毛。菌毛的功能至少有三种,即作为噬菌体
The theme of Professor Beman’s lecture in China this time is the new progress of infectious diseases in molecular biology and cell biology, which is divided into fifteen special topics and is summarized in four aspects: (1) on the ultrastructure of pathogenic bacteria (2) the interaction of obligate or facultative intracellular parasites with the host, (3) the role of host lymphocyte subsets and lymphokines in anti-infective immunity, (4) the study of the interaction between parasites and the host A new way of working. Now collated as follows: First, the observation of the ultrastructure of bacteria Bacteria flagella is composed of flagellin filament, curved hooked hook and sheath grana three parts. The grana is immobilized on the bacterial cytoplasmic membrane and cell wall by four circular structures. Shank and grana are flaps when the motion of the hub. There are also short and straight fimbriae on the surface of Gram-negative bacilli. Pili at least three functions, that is, as a phage
