Anthrax, caused by Bacillus anthracis, is an infection of animals and man.
The spore of this organism is remarkably resistant to drying out, and can exist dormant for decades.
The lesion, also called a "malignant pustule", develops as a tender red papule with a bulla that evolves into a hemorrhagic crust. Small vesicopustules surround this central lesion.
In untreated cases fever, severe malaise and death can occur within a week of the development of the lesion.
- Penicillin G IV is the treatment of choice, being given for 10 days.
- When anthrax is suspected treatment should be given early, while awaiting culture results.
