Anthrax is a bacterial infectious disease that primarily affects hoofed animals. Through close contact with infected animals or by handling infected animal products the pathogen humans can conduct the disease. We differentiate pulmonal, gastrointestinal and cutaneous anthrax. Anthrax bacteria in the blood can lead to sepsis, rapidly leading to death. The diagnosis is based on the clinical picture and history of the patient and the verification of the pathogen from samples. The treatment of choice is the early administration of ciprofloxacin.
