Genetic characterization of Theileria equi infecting horses in North America: evidence for a limited source of U.S. introductions

Abstract

The placement of most T. equi into one monophyletic clade by 18S is suggestive of a limited source of introduction into the U.S. When applied to a broader cross section of worldwide samples, these molecular tools should improve source tracking of T. equi outbreaks and may help prevent the spread of this tick-borne parasite.
