What is the recommended treatment for cutaneous anthrax?

The recommended treatment for cutaneous anthrax is indeed penicillin G or ciprofloxacin. Cutaneous anthrax, caused by the bacterium Bacillus anthracis, typically presents as a localized, painless ulcer with a characteristic black necrotic eschar. While the condition is generally self-limiting, antibiotic treatment is essential for preventing systemic spread and potential complications.

Penicillin remains the drug of choice, particularly in cases involving non-complicated cutaneous anthrax. It is effective against the bacterium, which is susceptible to beta-lactam antibiotics. Ciprofloxacin is also recommended, especially in cases where penicillin allergies are present or for more severe cases. As a fluoroquinolone, it has broad-spectrum activity and is particularly useful given the potential for Bacillus anthracis to develop resistance.

Other options listed, such as clindamycin, amoxicillin, or tetracycline, while they may have some efficacy, do not match the effectiveness and guidelines as strongly as penicillin and ciprofloxacin. Therefore, they are not considered the first-line treatments for cutaneous anthrax.
