ABSTRACT
Varadharajan A, Gnanasekar R , Kothandaraman S, Sivasakthivelan P., Effect of Betel nut (Areca
catechu), Neem (Azadirachta
indica)leaf and Fenbendazole
against liver fluke (Fasciola spp),
Onl J Vet Res., 24 (2):94-98,
2020. We report effect of 10 to 40% betel
nut (Areca catechu) (BNE) and Neem (Azadirachta indica) leaf extracts against standard
10% Fenbendazole and 25ml agar controls on viability
of adult fasciola spp. flukes. Flukes were assessed
for motility, gross and microscopic changes. Compared with agar controls where
flukes survived 8 hours, in those treated 10% BNE, were immobilized or killed
by 0.22min, 20% at 0.07min and in 40% BNE, upon contact (0 min) but in azadirachtin only by 220, 151, and 98 min, respectively. Fenbendazole stopped motility by 0.38 min. We found marked
gross and microscopic changes in flukes exposed to BNE but no effects in those
kept in neem extract. Our findings suggest that BNE may be effective in
controlling liver fluke.
Key-words:
Betel nut, Fasciola spp, Neem
leaf.
