Analysis on biological characteristics of Corynebacterium diphtheriae carried by healthy people 健康人携带的白喉棒状杆菌生物学性状分析
Objective: To investigate the biological characteristics of the strains of Corynebacterium diphtheriae carried by healthy people and the biological characteristic difference from the classical strains which can produce toxin. 目的:探讨健康人携带的白喉棒状杆菌的生物学特性及其与标准的产毒菌株的生物学性状的差异。
Results: The strains of Corynebacterium diphtheriae carried by healthy people had the classical cultural characteristics, did not produce toxin. 结果:健康人携带的白喉杆菌的培养特性典型均无毒力;
Diphtheria toxin is an exotoxin secreted by Corynebacterium diphtheriae that has been lysogenized by β bacteriophage that carries the DT gene. 白喉毒素(diphtheriatoxinDT)是棒状白喉杆菌被茁噬菌体感染后分泌的一种外毒素。
