The bacteria of
Anthrax is a gram-positive, spore-forming, rod-shaped (bacillus)
bacterium. It needs oxygen to thrive and has a capsule around it and
hence has a protective layer around it. A spore is a cell that is
dormant (asleep) but may come to life with the right conditions. Anthrax
spores are tasteless, odorless, and invisible. A bacterium is a very
small organism made up of one cell. Many bacteria can cause disease.
