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.
我们报告了 2009 年美国德克萨斯州南部的马梨形虫病暴发。在一些地区(292 匹感染马)感染率达到 100%。新月形锐缘蜱是主要的蜱种,并通过实验将马媾疫锥虫传播给了一匹未感染的马。我们认为,这种蜱种的传播在此次暴发中发挥了作用。
