Resumen
El presente estudio fue planteado con el objetivo de revisar sistemáticamente información de investigaciones publicadas sobre la prevalencia de hemotrópicos en ganado bovino del Ecuador en el periodo 2012-2022. Se seleccionaron las investigaciones por medio de criterios de inclusión y exclusión y se elaboró una base de datos con 51 estudios. Se tomó en cuenta los resultados de prevalencia para cada enfermedad Anaplasmosis, Babesiosis y Tripanosomiasis) calculados a nivel de bovinos y a nivel de predios dando como resultado un promedio de prevalencia en Anaplasma spp. del 55% (bovinos) y 82% (predios), en Babesia
spp. del 36% (bovinos) y 71% (predios) y en Trypanosoma spp. 11% (bovinos) y 61% (predios). Se evidencia que si existe una prevalencia significativa de hemotrópicos en todas las regiones del país, en estudios con muestreos de tipo probabilístico y no probabilístico, con diferentes métodos diagnósticos (PCR, ELISA, observación directa) y se pudo evidenciar también que existe una alta variabilidad en los resultados de los estudios analizados en el presente trabajo.
The present study was proposed with the objective of systematically reviewing information from published research about the prevalence of hemotropics in cattle of Ecuador in the period 2012-2022. The investigations were selected through inclusion and exclusion criteria and a database with 51 studies was created. The prevalence results for each disease (Anaplasmosis, Babesiosis and Tripanosomiasis) were calculated at the bovine level and at the farm level, resulting in an average prevalence of Anaplasma spp. 55% (cattle) and 82% (farms), Babesia spp. 36% (cattle) and 71% (farms) and Trypanosoma spp. 11% (cattle) and 61% (farms). It is evident that there is a significant prevalence of hemotropic in all regions of the country, in studies with probabilistic and non probabilistic tests, with different diagnostic methods (PCR, ELISA, direct observation) and it was also possible to demonstrate that there is a high variability in the results of the analyzed studies in this paper.
