Lyme disease bacteria. Coloured Scanning Electron Micrograph (SEM) of Borrelia burgdorferi bacteria, cause of Lyme disease in humans. These spiral shaped spirochaete bacteria are here coloured green. They are passed on to humans by tick bites, and occur in the midgut of the tick. Several tick species harbour these bacteria, the principal vectors being: Ixodes ricinus in Europe; I. pacificus in North America. The ticks can infest domestic dogs. Symptoms of Lyme disease include skin lesions, muscle pain, neurological and cardiac abnormalities, and arthritis. Treatment includes antibiotic and corticosteroid drugs.
