Scanning electron micrograph of Bacillus anthracis, commonly known as anthrax. These rod-shaped, Gram-positive, spore-forming bacteria can infect the skin (cutaneous anthrax), causing raised itchy lesions, the lungs (pulmonary anthrax), which is fatal unless treated quickly, and the digestive system (gastrointestinal anthrax), causing vomiting of blood and severe diarrhoea. All forms can be fatal if left untreated.
