Bovine fascioliasis in Peru is highly prevalent in almost all regions; however, there are few studies about its prevalence in the region of Amazonas. This research aimed to determine the prevalence and risk factors associated with fascioliasis from four livestock basins in the Amazonas region. A total of 941 bovine feces samples were analyzed and a prevalence of 52% was found. The highest prevalence was registered in females (53.9%), crossbred (58.6%), and producers with less than 50 animals (54.40%). The highest risk factor was for Brown Swiss (2.1), crossbreeds (2.4), heifer (4.1), females (1.4), and bovine that drinks water from streams (2.5) and waterhole (2.4). With the principal component analysis, 5 groups were identified, where the first explains that the area of the farm and the number of animals are related to the prevalence of fascioliasis. Group five indicated a relationship between the drinking water source and the breeds with the highest prevalence of fascioliasis. The results show that there are high prevalence and risk factors that affect livestock productivity and welfare. For this reason, there is a need to improve veterinary and animal health support, as well as training in livestock management, providing adequate sources of nutrition, and improving drug administration.

El estudio tuvo por objetivo evaluar la eficacia de cuatro antihelmínticos en el control de Fasciola hepatica en la Estación Experimental del Instituto Nacional de Innovación Agraria (INIA), Baños del Inca, Cajamarca, Perú. Se utilizaron 40 cuyes de 5 a 12 meses de edad, de la línea Inka infectados naturalmente con F. hepatica (>1 HPG) no desparasitados en los últimos 4 meses, bajo el mismo sistema de manejo y alimentación. Los cuyes fueron distribuidos en cuatro grupos (n=10): triclabendazol (25 mg/kg), closantel (20 mg/kg) vía oral, clorsulón + ivermectina (15 mg/kg en base a clorsulón) y nitroxinil (50 mg/kg), vía subcutánea. Se determinó la carga parasitaria el día 0 y 30 posdosificación. El Test de Reducción del Conteo de Huevos determinó una eficacia de 0% para triclabendazol y 100% para closantel, clorsulón + ivermectina, y nitroxinil. Se concluye F. hepatica es resistente al triclabendazol y sensible a closantel, clorsulón + ivermectina y nitroxinil en cuyes del INIA-Cajamarca.
