is anthrax bacteria motile
Anthrax is caused by bacteria that are a rod shaped organism, Bacillus anthracis. Anthrax is a non-motile organism between 1-5 micrometers in length. Upon exposure to air, anthrax forms a spore, which can become airborne to cause infection to exposed individuals. Anthrax spore can cause disease by coming in contact with abraded skin or wounds; inhalation; or ingestion. As anthrax reproduces, it releases three virulence factors: lethal factor, edema factor and antiphagocytic factor. Each of these substances enhances the destruction of cells and resists the immune system.
