    Pathogenesis of anthrax

    The bacteria produce dormant spores (not active) that can live in the environment like soil for a long time, even decades., When the spores get into the body of an animal or person, they can be activated and turn into active growing cells. , When they become active, the bacteria multiplies and spread out in the body, produces toxins ad causes severe illness and death.
