Anthrax is a rare bacterial infection. It can occur in wild and domestic hoofed animals, such as cattle, sheep and goats. It can also occur in humans when they are exposed to the bacterium. There are 3 forms of anthrax: cutaneous (skin), inhalation (lungs), and gastrointestinal (stomach and intestines). With intentional exposure, as in a bioterrorist release, breathing in the spores or contact with openings in the skin (cuts, scratches, abrasions, etc.) are the most likely routes of entry into the body. Gastrointestinal anthrax occurs when people eat meat from anthrax-infected animals. Anthrax can be treated successfully with antibiotics.
