Clinical diphtheria is caused by toxin-producing corynebacteria. Three species, Corynebacterium diphtheriae,
Corynebacterium ulcerans, and Corynebacterium pseudotuberculosis, have the potential to produce diphtheria
toxin and hence can cause classic respiratory diphtheria. Therefore, it is of critical importance to have
serological methods that are accurate, reproducible, specific, and sensitive.
