==Description==
Tyzzer's disease is an acute, highly fatal bacterial infection that is seen in a wide range of animals. It most commonly affects foals and laboratory animals as well as dogs, cats and calves. Foals are usually affected individually in sporadic cases whereas outbreaks of disease occur in rodents and rabbits. The bacteria that causes the disease is ''Clostridium piliforme'', a gram negative spore-forming intracellular bacterium.
The aetiology of the disease is poorly understood. Infection most likely results from oral exposure; possible mechanisms include ingestion of spore-forming faeces or contact with carrier animals.
