Only a few of the more than 90 species of Babesia cause disease in humans including, Babesia microti and Babesia microti-like species from the United States, Asia, and Europe, Babesia duncani (WA1) from California and Washington State, Babesia divergens and Babesia divergens-like species from Europe and the United States, and Babesia venatorum (EU1) from Europe.2-3
