Anthrax, contagious disease of warm-blooded animals, including humans, caused by the bacterium Bacillus anthracis.
In humans, the disease appears in both external and internal forms, with a death rate of about 20 percent. The external or cutaneous form is contracted through cuts or abrasions in the skin by those who handle infected hides and carcasses and may be self-limiting, but often disseminates into the bloodstream, with fever and prostration. It is characterized by malignant pustules on exposed skin areas. The internal type is acquired by inhaling anthrax spores, as from animal hair and wool, which invade the lungs and sometimes the intestinal tract to cause hemorrhage. It is speculated that an intestinal variety may be caused by consuming contaminated meat or milk. Workers exposed to animal products, especially wool, are protected by vaccination. Penicillin and tetracyclines are effective in treatment except in rapidly progressing cases.
