Tetanus toxin is produced by C. tetani bacteria as a single polypeptide chain of 150 000 Da and then cleaved into two linked polypeptides – a 100 000 Da heavy chain and a 50 000 Da light chain. The toxin is extremely potent; the estimated human lethal dose is less than 2.5 ng per kg. The toxin migrates to its site of action in the central
Clostridium tetani. — Spores of C. tetani are found everywhere in the environment. — Tetanus occurs when spores enter the human body through wounds and produce neurotoxin. — Vaccination against tetanus is the main means of protection. The burden of maternal and neonatal tetanus (MNT) is a health equity issue affecting
