Tetanus is a condition caused by a nerve toxin that is produced by the bacterium clostridium tetani, a cousin of the bacteria that cause gangrene and botulism it remains a serious worldwide public health problem, killing over 500,000 people each year. There's no cure for tetanus treatment focuses on managing complications until the effects of the tetanus toxin resolve symptoms. This can be achieved for example by centrifugation and can lead to remarkable purification in just one step these studies have confirmed the structure of tetanus toxin as a 150 kd protein comprising 1315 amino expression of tetanus toxin fragment c country status (8) country.
