Resumen:
Haemonchus contortus is a highly pathogenic blood-feeding parasite affecting sheep and goats, leading to significant economic losses. With increasing resistance to conventional anthelmintics, exploring plant-based alternatives is crucial. In vitro, studies suggest that peruvin and hentriacontane/1-nonacosanol, isolated from Artemisia cina (Asteraceae), may synergistically control Haemonchus contortus. However, their in vivo efficacy and safety are unestablished. This study evaluated these compounds' anthelmintic activity and health effects and their synergistic mixture in Meriones unguiculatus (gerbils). The compounds were isolated using open-column chromatography and identified by spectroscopic techniques. Gerbils were artificially infected with H. contortus following dexamethasone treatment to enhance infection. Anthelmintic activity was assessed by larval reduction in the stomach, blood biochemical parameters using a blood chemistry analyzer, and the anatomopathological changes in kidney and liver tissues. Peruvin (0.4 mg/kg) and hentriacontane/1-nonacosanol (2.60 mg/kg) achieved larvicidal reductions of 84.86 % and 74.05 %, respectively, while their synergistic mixture (0.08/0.0017 mg/kg) resulted in a 100 % reduction. Histopathological analysis revealed minor inflammation and albuminous degeneration, primarily affecting the liver. The peruvin-treated group showed notable kidney damage, while hepatic alterations were similar across both compounds. Although effective, further research is needed to optimize dosing and ensure safety © 2024
