Abstract
Anthrax is caused byBacillus anthracis, an encapulated and spore-forming bacillus. The disease is usually contracted through uptake of spores that remain viable in the contaminated soil for many years. Anthrax is primarily a disease of herbivorous animals and is uncommon in humans who may get the infection through contact with contaminated animals or their products. Anthrax spores germinate after entering the body through skin abrasions (cutaneous anthrax) or by inhalation (inhalation anthrax) or ingestion (gastrointestinal anthrax) and multiply to produce two exotoxins which determine the virulence along with capsule. Although most cases occur within 48 hours of exposure, germination of spores may occur upto 60 days later. While inhalation anthrax is almost always fatal, intestinal anthrax results in death in 25% to 60% of cases. Upto 20% of cases having cutaneous anthrax may die. Antibiotics are effective if the disease is recognised early and treated appropriately. Penicillin is the drug of choice when disease occurs in natural setting. Ciprofloxacin is recommended when aerosols of anthrax spores are used as bioweapon, prophylactic antibiotics should not be prescribed until risk of exposure is considered real by experts.
