[Tetanus and Clostridium tetani--a brief review].

Tetanus is an acute, often fatal, disease caused by an exotoxin (tetanospasmin) produced by the anaerobic, gram-positive spore-forming bacterium Clostridium tetani. It is characterized by generalized rigidity and convulsive spasms of skeletal muscles. In most industrialized countries, tetanus is a rare disease. However, in many tropical and subtropical countries with low vaccination coverage and poor medical care, it is still widely distributed. This applies in particular for neonatal tetanus. About 50 000 newborns and infants die each year from consequences from this severe illness. Management of tetanus involves neutralization of free circulating toxin, adequate antibacterial and symptomatic therapy as well as intensive care of the patient. For prophylaxis of the disease, active tetanus toxoid vaccination is the method of choice.
