“…Evidence suggests that this tick species can transmit Babesia caballi (Schwint et al, 2008), but not Theilleria equi (Stiller & Coan, 1995). Interestingly, in a previous study, we were able to identify both pathogens in horse blood by using a competitive ELISA (Wise et al, 2016). This indicates the need for effective prevention and treatment of tick infestations, despite the lack of clinical signs in the tested horses.…”

“…Additionally, two studies describe the pharmacokinetics of ectoparasiticides (avermectins) in horses, but the data were not linked to efficacy and safety (Gokbulut et al, 2010(Gokbulut et al, , 2016. Horses on the island of Grenada are commonly infested by ticks and the most prominent tick species found is the one-host tick Dermacentor nitens, although Rhipihcephalus spp have incidentally also been observed on the horses (Wise et al, 2016). Evidence suggests that this tick species can transmit Babesia caballi (Schwint et al, 2008), but not Theilleria equi (Stiller & Coan, 1995).…”

Several different tick species are known to infest horses. Aside from causing serious health and welfare issues, including anaemia, ill thrift, and immunosuppression, ticks can transmit a variety of important, sometimes zoonotic, pathogens. The successful prevention and treatment of tick infestations have been described, but the information is scarce and, in many instances, anecdotal. Here we describe a practical and affordable prevention of tick infestation by using abamectin‐impregnated cattle ear tags affixed to a safety collar. We have assessed the radial distribution of abamectin by analyzing hair samples, as well as its efficacy against tick infestations. The study results show that abamectin distributes across horse skin from the site of application and its associated effectiveness in reducing the tick burden.
