Bacillus anthracis
Last reviewed 01/2018
Anthrax is caused by Bacillus anthracis.
The organism produces its effects mainly by invasive adaptations but also by the formation of a powerful exotoxin.
The spores of Bacillus anthracis are extremely hardy and can withstand extremes of temperature and humidity. Transmission of the disease is through direct contact with an infected animal and is seen in farmers, butchers and dealers in wool and animal hides. The Bacillus anthracis spores may be ingested or inhaled.
