Cutaneous anthrax is a bacterial infection that affects the skin and is caused by the spore-forming bacteria, Bacillus anthracis. This disease is rare and is typically acquired through contact with infected animals or contaminated animal products such as wool, hair, and hides.
The spores of B. anthracis are highly resistant to heat, drying, and other environmental stressors, which allows them to survive for long periods in soil and animal products. When spores enter the body through a cut or scrape on the skin, they can germinate and release toxins that cause the symptoms of cutaneous anthrax.
Symptoms of cutaneous anthrax usually appear within 1-7 days after exposure and include a small painless bump that quickly develops into a blister with surrounding swelling. The blister then turns into a painless ulcer with a black center, known as an eschar. Other symptoms can include fever, headache, and swollen lymph nodes near the affected area.
Cutaneous anthrax can usually be diagnosed by examining the symptoms and the presence of the characteristic eschar. Laboratory testing of a skin biopsy or culture of the bacteria can confirm the diagnosis.
Treatment for cutaneous anthrax typically involves antibiotics such as ciprofloxacin, doxycycline, or penicillin. In addition, antitoxin therapy may be used to neutralize the toxins produced by the bacteria. The earlier the treatment is started, the better the outcome, and most patients respond well to treatment.
Prevention of cutaneous anthrax involves proper handling and disposal of ani...
