<unk><unk>  is caused by Borrelia burgdorferi and is transmitted primarily by tick species Ixodes scapularis. Ticks can attach to any part of the human body but are often found in hard-to-see areas such as the groin, armpits, and scalp. In most cases, the tick must be attached for 36 to 48 hours or more before the spirochetes can be transmitted. Very few people affected with<unk><unk>  recall a tick bite. B. burgdorferi have two morphological forms, a spiral form and a spheroplast form. Survival strategies of B. burgdorferi include: antigenic variation, physical sequestration, intracellular invasion, and immune system supression.
