Prevalencia de hemoparásitos en caballos Equus caballus en los cantones Portoviejo y Chone – Provincia de Manabí.

Abstract

Hemoparasites are a silent threat that compromises the health of all equine species and generates significant productivity losses in the equine industry in economic impact. The objective of this study was to determine the prevalence of hemoparasites in horses in the Portoviejo and Chone cantons of the Manabí Province. The blood smear technique with Giemsa staining was used to identify the protozoan agents Babesia caballi, Theileria equi and Trypanosoma evansi. This study has a correlational, explanatory and descriptive scope. The INFOSTAT statistical program and ANOVA and Tukey statistical tests were used. Through the Working in Epidemiology program, a necessary sample size of 106 horses was obtained from a population size of 26,284 horses from the province of Manabí, with a confidence level of 95 % and a minimum expected prevalence of 2.80 %, The biological sample was obtained by venipuncture of the jugular vein. A prevalence of 6.60 % 7/106 horses with Babesia caballi was determined, no morphologies of Theileria equi and Trypanosoma evansi were observed. An average of Hto and Hb of 39.00% and 12.66 g/dL of positive cases for B. caballi was obtained, it was established that there are no significant differences between both values with prevalence. Significant differences were reported between prevalence and place, type of accommodation, contact with other animals, zootechnical purpose. A correlation between prevalence and the variables age of 92 %, Hto.43 % and Hb was obtained. 62 %.
