Borrelia burgdorferi belongs to which group of bacteria?

Explanation:
Borrelia burgdorferi is a spirochete, a slender, corkscrew-shaped bacterium with periplasmic flagella that give it a distinctive spiral motility. This group includes Treponema and Leptospira and is separate from both Gram-positive cocci and Gram-negative diplococci, as well as from fungi. Spirochetes are bacteria (usually considered Gram-negative in staining), which explains why Borrelia burgdorferi is categorized with spirochetes rather than the other groups. This organism is what causes Lyme disease and is transmitted by ticks.
