Lyme disease

English: Lyme disease or Lyme borreliosis is the most common tick-borne disease in the United States and Europe. Lyme disease is caused by a bacterial infection with a spirochete from the species complex Borrelia burgdorferi sensu lato, and is most often acquired from the bite of an infected Ixodes tick. Lyme disease has many signs and symptoms, but skin signs, arthritis and/or various neurological symptoms are often present.
