Efficacy of Aqueous and Methanol Extract of Against the Motility of .

Gastrointestinal nematode infections can cause great losses in revenue due to decrease livestock production and animal death. The use of anthelmintic to control gastrointestinal nematode put a selection pressure on nematode populations which led to emergence of anthelmintic resistance. Because of that, this study was carried out to investigate the efficacy of aqueous and methanol extract of against the motility of Bristol N2 and DA1316. Bristol N2 is a susceptible strain and DA1316 is an ivermectin resistant strain. bioassay of various concentrations of (0.2, 0.6, 0.8, 1.0 and 2.0 mg mL) aqueous and methanol extracts of was conducted against the motility of L4 larvae of Bristol N2 and DA1316. The L4 larvae were treated with 0.02 μg mL of ivermectin served as positive control while those in M9 solution served as negative control. The activity of the extracts was observed after 24 h and 48 h. A significant difference was recorded in the extract performance compared to control at ( < 0.001) after 48 h against the motility of the larvae of both strains. The methanol extracts inhibited the motility of Bristol N2 by 86.7% as well as DA1316 up to 84.9% at 2.0 mg mL after 48 h. The methanol extract was more efficient than aqueous extract ( < 0.05) against the motility of both strains of may be used as a natural source of lead compounds for the development of alternative anthelmintic against parasitic nematodes as well ivermectin resistant strains of nematodes.
