Equine piroplasmosis associated with Amblyomma cajennense Ticks, Texas, USA

Emerg Infect Dis. 2011 Oct;17(10):1903-5. doi: 10.3201/eid1710.101182.

Abstract

We report an outbreak of equine piroplasmosis in southern Texas, USA, in 2009. Infection prevalence reached 100% in some areas (292 infected horses). Amblyomma cajennense was the predominant tick and experimentally transmitted Theileria equi to an uninfected horse. We suggest that transmission by this tick species played a role in this outbreak.
