Estudio epidemiológico de la prevalencia parasitaria (endoparásitos-ectoparásitos) en bovinos en 3 parroquias del cantón Morona.

Abstract

In the Ecuadorian Amazon, cattle ranching is fundamental to the economy of small farmers, but faces significant challenges such as inadequate pasture management and lack of deworming schedules. The empirical use of techniques and drugs without control or registration has generated a false sense of security, which, added to the lack of accurate diagnosis and inadequate use of antiparasitics, is causing resistance and becoming a serious problem. Therefore, it is crucial to improve the management and control of animal health to ensure the sustainability of livestock farming in the region. In this context, an investigation was carried out to determine the parasitic prevalence in the parishes of Macas, General Proaño and San Isidro in Morona canton. Fecal samples were collected from 371 animals, and saline flotation and McMaster techniques were implemented in the laboratory. The results showed that 183/371 females and 33/371 males were positive cases. The helminths with the highest prevalence belonged to the nematode type, with Bunostomum phlebotomum (21.18%) and Toxacara vitulorum (19.21%) being the most common. The nematode and trematode association with the highest prevalence was Bunostomum phletonum-Fasciola hepatica (24.49%). In conclusion, the implementation of coproparasitic studies is recommended to specifically treat parasites and improve animal health in the region.
