 | Lyme disease is an infection caused by the corkscrew-shaped
bacteria Borrelia burgdorferi that is transmitted by the bite of
deer (Ixodes scapularis) and western black-legged (Ixodes pacificus) ticks. The deer tick, which normally feeds on the
white-footed mouse, the white-tailed deer, other mammals, and
birds, is responsible for transmitting Lyme disease bacteria to
humans in the northeastern and north-central United States. On
the Pacific Coast, the bacteria are transmitted to humans by the
western black-legged tick. |
