CHAPARRO-GUTIERREZ, Jenny J. et al. Prevalence of gastrointestinal parasites in equines and associated risk factors in several areas of Antioquia, Colombia. Ces. Med. Vet. Zootec. [online]. 2018, vol.13, n.1, pp.7-16. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.13.1.1.

There are few reports on the prevalence of gastrointestinal parasites in equines in Colombia. In this study946 ׳ horses were sampled from a total of 204 farms in the municipalities of Rionegro and those that comprise the Valle de Aburrá׳ in the department of Antioquia. Fecal samples were taken directly from the rectum and processed by the McMaster׳ Baermann and Graham techniques. The prevalence of parasites at the farm level was 56.3% for Strongyüdae10.7% ׳ for Strongyloides spp2.8% ׳ for Oxyuridae and 0.3% for Dictyocaulus spp. From a practical point of view׳ the most pathogenic parasites and of greatest resistance concern were the Cyathostomids׳ which are included within the Strongylidae and whose prevalence was greater than 50%. The OR of presenting Strongylidae was 49% lower in equines that participated in fairs compared to those that did not. The OR of presenting Strongylidae was 56% lower in equines that use stables than those not being stalled. A1so׳ the OR of being positive to Oxyuris equi was 88% lower in animals that participate in fairs compared to those that did not׳ and was 3.66 times higher in equines with body condition < 2 in comparison with those of body condition >3. Based on this information it is important to initiate studies that evaluate the state of antihelminthic resistance and the relationship between parasitic load and clinical condition in order to determine the real impact of these parasites on the equines of these regions.
