Lyme disease is an infection caused by Borrelia burgdorferi, a member of the family of spirochetes, or corkscrew-shaped bacteria.
Lyme disease is spread by the bite of ticks of the genus Ixodes that are infected with Borrelia burgdorferi. The deer (or bear) tick, Ixodes dammini, 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.
Ixodes ticks are much smaller than common dog and cattle ticks. In their larval and nymphal stages, they are no bigger than a pinhead. Adult ticks are slightly larger.

It is predominantly deer ticks or western black-legged ticks. However, the tick itself must be infected with B. burgdorferi bacteria. A healthy tick will not transmit lyme disease.
