Preliminary study of ectoparasites of horses in the western highlands of Cameroon.

Abstract

To evaluate the prevalence of infestation of ectoparasites of horses, a total of 894 horses (367 males and 527 females), aged 1–7 years old were examined. Horses were groomed for collection of ectoparasites. Out of the horses examined, 164 came from Fundong, 80 from Acha, 30 from Fongo‐Tongo, 30 from Fokoue and 17 from Dschang, all of which were infested with ectoparasites. Five hundred and seventy‐three (573) horses came from Banso and 99.48% were infested by ectoparasites. From the results obtained, three species of hard ticks (Boophilus decoloratus, Amblyomma hebraeum and Hyalomma rufipes) and one species of biting lice (Bovicola equi) were identified. Boophilus decoloratus (66%) had the highest prevalence per locality, followed by A. hebraeum (18%), H. rufipes (11%) and B. equi (5%). Boophilus decoloratus infested horses of all ages, sex or colour. Meanwhile, A. hebraeum and H. rufipes had a higher prevalence in adult male horses. Mono‐parasitic infestation (69%) was more common than poly‐parasitic infestation (31%). Only three horses were free from infestation with ectoparasites. Understanding the biology, epidemiology and economic impact on the equine industry is important for public health and disease prevention programmes.
