the geographic distribution and ecological preferences of the american dog tick, dermacentor variabilis (say), in the u.s.a.	equine piroplasmosis (ep), caused by two parasitic organisms, theileria equi and babesia caballi, is a tick-borne disease of recent concern in horses in the u.s.a. outbreaks of ep have been detected in florida, missouri, kansas and texas. in 2009, ep transmission in texas occurred through the adults of two tick species, amblyomma mixtum [formerly known as amblyomma cajennense (fabricius, 1787)] koch (ixodida: ixodidae) and dermacentor variabilis (say) (ixodida: ixodidae), the american dog tick ( ...	2015	25684582
