The main threat, however, is not inflammation, but poisoning with a toxin, which is produced by the bacterium, the causative agent of the disease, while the cardiovascular and nervous systems are mainly affected.
The causative agent of diphtheria and infection

Diphtheria bacilli secrete diphtheria toxin, the enzyme neuraminidase and other biochemically active compounds in the process of life. Continue reading
