[Pulmonary anthrax].

Anthrax is a zoonotic disease caused by Bacillus anthracis. Skin disease is the most common form in humans. Pulmonary anthrax related to the inhalation of airborne germs develops after a silent incubation period of several days and followed by acute respiratory distress. Diagnosis is a difficult task and generally based on demonstration of Bacillus anthracis on direct examination. Despite the sensitivity of B. anthracis to penicillin, treatment is rarely successful.
