- Target
- Corynebacterium diphtheriae is a Gram-positive, non-motile bacterium that can cause serious illness in unvaccinated humans. C. diphtheriae infects the epithelial cells of the upper respiratory tract from where they secrete a potent toxin that is absorbed and disseminated through lymph channels and blood to the susceptible tissues of the body. The toxin is a single protein chain of 62 kDa which is "nicked" at proteolytic processing sites to produce an A chain of 21 kDa and a B chain of 40 kDa, held together by a disulfide bridge. The A-chain carries the ADP-ribosylation enzymatic activity responsible for the toxic action.

-
ELISA
HYB 123-05 reacts strongly with diphtheria toxoid. HYB 123-05 detects diphtheria toxoid in sandwich ELISA in combination with a polyclonal antibody against the toxoid as capture antibody (1). Strong reaction is also seen in ELISA with diphtheria toxoid coated directly onto the microtiter well.
An antibody pair consisting of HYB 123-09 and HYB 123-05 can be used in a sandwich ELISA when using HYB 123-09 as a coat and biotinylated HYB 123-05 a detection antibody (1).

文献和实验以加入菌体外霉素、抗毒素等各种方法进行处理,使其抗原性不发生改变而毒性被减低的一种物质。类毒素一词为P. Ehrlich所命名。一般使用类毒素可使活体对细菌毒素产生能动性免疫。为人们所熟知的是白喉类毒素的福尔马林处理物制成的减毒素( ana- toxin: G. Ramon, 1932)。
细菌的外毒素经甲醛处理后,失去毒性而仍保留其免疫原性,能刺激机体产生保护性免疫的制剂。常用的甲醛溶液的浓度是0.3~0.4%。它可使细菌外毒素的电荷发生改变,封闭其自由氨基,产生甲烯化合物(CH2 =N-)。其他基团(如吲哚异吡唑环)与侧链的关系亦可改变,成为类毒素。常用的类毒素有白喉类毒素,破伤风类毒素。另外,若在类毒素中加入适量的磷酸铝或氢氧化铝,即成吸附精制类毒素。该类制剂在体内吸收较慢,能较长时间刺激机体,使机体产生高滴度抗体,增强免疫效果。类毒素也可与死疫苗混合
白喉杆菌(corynebacterium diphtheriae)
白喉杆菌(corynebacterium diphtheriae)是引起小儿白喉的病原菌,属于棒状杆菌属(corynebacterium)。棒状杆菌种类较多,包括白喉杆菌和类白喉杆菌。类白喉杆菌为非致病菌,常见的有假白喉杆菌,结膜干燥杆菌、溃疡杆菌和痤疮杆菌等。本章介绍白喉杆菌。 白喉杆菌细长稍弯,排列不规则,常呈l、v、x、t等字形或排成栅栏状。革兰氏染色阳性;用美兰液染色菌体着色不均匀,常呈着色深的颗粒;用奈瑟氏染色菌体染成黄褐色,一端或二端染成兰
