Efecto del paico (Chenopodium ambrosoides) en el control de nematodos en caninos (Canis lupus familiaris)

Abstract

The objective of this study was to evaluate the antiparasitic effect of Paico (Dysphania ambrosoides) 500 mg tablets in canines (Canis lupus familiaris). Forty-eight dogs from the Patitas Nobles Foundation, located in Ambato, were used, distributed in four sections with three blocks in each section, and four canines per block. The animals received Paico 500 mg tablets, administered in a single dose of 10, 15 and 20 mg/kg. Coprological examinations were performed using the Willis direct single flotation technique to identify parasites and egg counts present in fecal samples using the McMaster chamber. The examinations were performed before treatment and 7 days after tablet administration. Two parasite species were identified: Toxocara canis and Trichuris vulpis. The results showed that the effectiveness of treatment with Paico tablets increased with the dose administered, reaching a reduction of 39.65 % for T. canis and 49.62 % for T. vulpis with the 20 mg/kg dose. These results suggest that Paico tablets at higher doses may be a promising option for the control of intestinal parasites in canines, although further studies are required to optimize the doses and administration regimen.
