Anthrax is an infectious disease due to a type of bacteria called Bacillus anthracis. Infection in humans most often involves the skin, gastrointestinal tract, or lungs.
Anthrax commonly affects hoofed animals such as sheep, cattle, and goats, but humans who come into contact with infected animals can get sick from anthrax, too. In the past, the people who were most at risk for anthrax included farm workers, veterinarians, and tannery and wool workers.
Bacillus anthracis is a soil living bacterium, occures worldwide. It is also used as biological weapon, for example the virulent Ames-strain and the Vollum-strain. The Sterne-strain is used for vaccine production.
