Description

Bacillus anthracis is a Gram-positive facultative aerobic spore-forming bacterium found in the soil. B. anthracis derived its name from the Greek word for coal because this pathogen can cause black lesions on the victim's skin. The bacterium is non-motile and non-hemolytic on blood agar. B. anthracis is found mostly in spore-form in the environment, but when it has infected a host it will germinate and replicate in essentially all body tissues. When anthracis is in the spore form, it is resistant to most adverse environments and can survive for many decades.
