Presencia de resistencia mixta en una majada de ovejas y primer hallazgo de resistencia a las avermectinas de Cooperia curticei en un establecimiento de la provincia de Salta, Argentina

Abstract

El objetivo del presente trabajo es describir un caso de resistencia mixta, registrándose por primera vez baja eficacia antiparasitaria contra Cooperia curticei en una majada ovina en la provincia de Salta. El trabajo fue llevado a cabo en un establecimiento de la localidad de Cerrillos, provincia de Salta. Se conformaron 4 grupo de 10 animales cada uno, un grupo control, un grupo tratado con ivermectina, otro tratado con albendazol y otro tratado con levamisol. Los resultados de eficacia fueron de 50,5% para ivermectina, de 68,7% para albendazol y de 99,2% para levamisol. En cuanto a la eficacia por genero, fue de 42,8%, 64,8% y 97% en Haemonchus contortus, de 100%, 70,2% y 99,3% para Trichostrongylus colubriformis y de 88,5%, 100% y 100% para C. curticei para ivermectina, albendazol y levamisol respectivamente. Este hallazgo alerta sobre la situación de RA y debe considerarse la amplia distribución del uso de varios grupos químicos en estudien las majadas de la region.

The aim of this work is to describe a case of mixed resistance, finding for the first time low antiparasitic efficacy against Cooperia curticei in a sheep flock in the province of Salta. The work was carried out in an establishment in Cerrillos town, province of Salta. Four groups of 10 animals each were formed: a control group, a group treated with ivermectin, another treated with albendazole and another treated with levamisole. The efficacy results were 50.5% for ivermectin, 68.7% for albendazole, and 99.2% for levamisole. Regarding the efficacy by gender, it was 42.8%, 64.8% and 97% in Haemonchus contortus, 100%, 79.2% and 99.3% for Trichostrongylus colubriformis and 88.5%, 100 % and 100% for C. curticei for ivermectin, albendazole and levamisole respectively. This finding warns about the AR situation and of the wide distribution of the use of various chemical groups under study in the region's flocks, which should be considered.
