. Pathology. | 1. | an infectious, often fatal disease of cattle, sheep, and other mammals, caused by Bacillus anthracis, transmitted to humans by contaminated wool, raw meat, or other animal products. |
| 2. | a malignant carbuncle that is the diagnostic lesion of anthrax disease in humans. |

An infectious disease transmitted by a bacterium in animals, which can also be transmitted to humans. Often fatal if the bacterium enters the lungs, anthrax is usually treated by antibiotics. Anthrax is a potential weapon in germ warfare and bioterrorism.
Note: After the September 11 attacks (2001) in the United States, anthrax spores sent through the mail caused several fatalities.
Note: If spores are prepared in a sophisticated way, they can stay in the air and be breathed in by human beings. Anthrax produced in this way is referred to as weaponized anthrax.
