In-vitro effect of the methanolic extract of Momordica charantia on hatching of eggs of Haemonchus sp

Background: Endoparasitism, particularly infections by gastrointestinal nematodes (e.g., Haemochus sp.), has been associated with economic losses within sheep production systems in tropical regions. Thus, implementing therapeutic alternatives that are environmentally sustainable is essential for parasite integral control programs. Objectives: Evaluate in-vitro the effect of Momordica charantia methanolic extract on the Haemonchus sp. eggs' hatching process. Methods: Nematode eggs were retrieved from experimentally infected sheep and exposed to 10, 20, 40, 80, and 160 mg/mL of methanolic extract of M. charantia. Hatching percentages were recorded from five replicates, and CL50 and CL90 were estimated through Probit regression analysis. Results: A significant effect on the hatching percentages were observed, from 24.2% up to 84.6% inhibition (p
