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. B. burgdorferi is a gram-negative bacteria, and has the elongated and spiral shape of the spirochetes 2. Can be very narrow and pass through filters that keep other bacteria out. While spirochetes are generally regarded as Gram negative bacteria, because they have a thin peptidoglycan, Gram staining is not commonly used to stain them. The mechanisms that determine bacterial shape are in many ways poorly understood.
