Babesiosis is a zoonotic disease maintained by the interaction of tick vectors, transport hosts, and animal reservoirs. [9] The primary vectors of the parasite are ticks of the genus Ixodes. In the United States, the black-legged deer tick, Ixodes scapularis (also known as Ixodes dammini), is the primary vector for the parasite; in Europe, Ixodes ricinus appears to be the primary tick vector. [10] In each location, the Ixodes tick vector for Babesia is the same vector that locally transmits Borrelia burgdorferi, the agent implicated in Lyme disease.
