Anthrax is a serious, often fatal zoonotic disease of wild and domestic mammals caused by the spore-forming bacterium [[Bacillus anthracis]]. The disease has been reported worldwide and often in outbreaks. The infected host sheds bacteria into the environment which sporulate when exposed to air. These spores are highly resistant and can survive in the environment for many years.  Grazing animals may become infected if ingestion of a large number of spores occurs. Additionally, biting flies appear to have a role in transmission of spores in areas of endemic disease. Inhalation of dust-borne spores may also be of importance.

Humans may be infected via contact with infected animal tissues, exposure to high concentrations of spores or contacted with infected animals.
