How is Lyme disease transmitted?
In the USA, the bacteria are transmitted to people and animals by the bite of an infected blacklegged tick, Ixodes scapularis, commonly called the deer tick, and Ixodes pacificus (western black legged tick) in the West. Although other types of ticks such as the Dermancentor variabilis (american dog) and some insects have been shown to carry the Lyme bacteria, to date, transmission of Lyme through those vectors has not been proven. Note: Other tick borne disease have been transmitted though the blood supply.
