Borrelia burgdorferi is a microaerophile, requiring small amounts of oxygen in order to undergo glycolysis and survive. Like all other Borrelia sps., this bacterium is also gram-negative and a spirochete. Borrelia colonies are often smaller, rounded, and white with an elevated center. [7] B. burgdorferi possesses flagella that allow it motility.

Borrelia , like most spirochetes, does have an outer membrane that contains an LPS-like substance, an inner membrane, and a periplasmic space which contains a layer of peptidoglycan.
