Missouri Lyme disease is a cutaneous condition. The cause of ‘Missouri Lyme disease’ has been a source of controversy. True Lyme disease probably occurs in Missouri and other southern states, although Lyme disease-like illnesses not related to Borrelia burgdorferi also occur. Strains of B. burgdorferi have been isolated from A. americanum in Missouri, but the ticks are not efficient disease vectors.
