The disease is named after a European microbiologist, Victor Babes, who discovered the causative microorganism. Babesia species are parasites of mammals and birds that are currently classified in the subphylum Apicomplexa, together with those organisms that cause malaria (Plasmodium species) and toxoplasmosis (Toxoplasma gondii) (Fig. 337-1). Only a few of the more than 90 species of Babesia that have been described cause disease in humans, including Babesia microti from the United States, Asia, and Europe, Babesia duncani (WA1) from California and Washington state, MO1 from Missouri, Babesia divergens and Babesia venatorum from Asia and Europe, and KO1 from Korea.
