Under a magnification of 6,408X, this scanning electron micrograph (SEM) depicted spores from the Aimes strain of Bacillus anthracis bacteria. A key characteristic of the Aimes strain of B. anthracis is the smooth surface of the protein coat of these bacterial spores. These spores can live for many years which, enables the bacteria to survive in a dormant state. Anthrax is an acute disease caused by the bacterium Bacillus anthracis. Bacillus anthracis is a rod-shaped, Gram-positive, aerobic bacterium about 1 by 9 micrometers in length. Most forms of the disease are lethal, and it affects both humans and other animals. There are effective vaccines against anthrax, and some forms of the disease respond well to antibiotic treatment. When spores are inhaled, ingested, or come into contact with a skin lesion on a host, they may become reactivated and multiply rapidly. Anthrax spores can be produced in vitro and used as a biological weapon. Anthrax does not spread directly from one infected...
