Bacillus anthracis infection, also known as anthrax, is a serious and potentially lethal bacterial disease. Some common synonyms for this condition include wool sorter's disease, ragpicker's disease, and charbon. Wool sorter's disease refers to the fact that Bacillus anthracis is often found in animals such as sheep and goats, which are common sources for wool. Ragpicker's disease is a term used to describe the disease's possible association with handling and sorting textiles. Charbon is the French word for anthrax, and this synonym is often used in medical literature. Regardless of the term used, Bacillus anthracis infection requires immediate medical attention and prompt treatment to prevent serious complications.
