Symptoms include the formation of carbuncles (inflammation of hair follicles and surrounding subcutaneous tissue) and swelling at the location of the infection (Photo 8.10). Scabs form over the lesion and turn a coal-black. Anthrax is the Greek term for coal, and so the name is derived from the coal-black scabs on the lesions. This localized infection can also become systemic and transformed to the inhalation form of the disease.
