Lyme Disease

Lyme disease is due to four main species of bacteria: Borrelia burgdorferi, Borrelia mayonii, Borrelia afzelii and Borrelia garinii. The bacteria Borrelia burgdorferi and Borrelia mayonii cause Lyme disease in the United States, while the bacteria Borrelia afzelii and Borrelia garinii are the main causes in Europe and Asia. The most common disease associated with ticks in these regions, Lyme disease, is transmitted by the bite of an infected black-legged tick, commonly known as "deer tick".
