Equine piroplasmosis associated with Amblyomma cajennense Ticks, Texas, USA.

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.

This research article discusses an outbreak of equine piroplasmosis in Texas, USA in 2009, asserting that ticks, specifically the Amblyomma cajennense species, played a significant role in transmitting the Theileria equi parasite causing the disease.

Outline of the Study

  • The study focuses on an outbreak of equine piroplasmosis, a tick-borne disease that affects horses, in Southern Texas in 2009. This disease is caused by the protozoan parasites Theileria equi and Babesia caballi, transmitted by ticks.
  • The magnitude of the outbreak was significant, with the rate of infection reaching 100% in certain areas, meaning every horse in those locations was infected.

Amblyomma cajennense Ticks As The Vector

  • The research highlights that Amblyomma cajennense, a species of tick, was the predominant tick in the area during the outbreak of equine piroplasmosis.
  • An experiment carried out in the research showed that this species could transmit Theileria equi to an uninfected horse. This experimental evidence supports their hypothesis that this tick species played a significant role in the outbreak.

Implication and Suggestion

  • The research implies that controlling the population of Amblyomma cajennense ticks could be a key strategy in preventing future outbreaks of equine piroplasmosis.
  • Furthermore, the researchers suggest that a greater understanding of the role and behavior of this specific tick species could lead to more effective prevention and control measures.
