A 65-year-old alcoholic was taken to the emergency room with severe necrotic, blackened areas on both feet and several draining ulcers on his heels and toes. He was stuporous. His medical records indicated no vaccination history in the past 20 years. During that evening he had a seizure and was treated with phenytoin and barbiturates. By the end of the night he had developed increasing rigor and respiratory distress and was unresponsive. His neck was stiff and hvperextended and his teeth clenched in a grimace. Culture from the ulcers revealed gram positive bacilli that were terminal endospore formers. Specific therapy and supportive care led to his full recovery. 1. What organism is causing this disease?
