Spirochetes are a group of bacteria characterized by their unique spiral shape and flexible structure. They are known for their ability to move in a corkscrew motion, which helps them navigate through various environments, including viscous fluids. Spirochetes can be found in diverse habitats, such as soil, water, and the intestines of animals. Some spirochetes are pathogenic, meaning they can cause diseases in humans and animals. Notable examples include Treponema pallidum, which causes syphilis, and Borrelia burgdorferi, responsible for Lyme disease. Understanding spirochetes is important for both medical research and environmental studies.
