Persistent anthelmintic activity of topically administered ivermectin in red deer (Cervus elaphus L.) against lungworms (Dictyocaulus viviparus).
A controlled trial was conducted to evaluate the persistent anthelmintic effect of ivermectin as a topical treatment at 500 microg/kg against induced infection with lungworm (Dictyocaulus viviparus) in red deer (Cervus elaphus). The results showed a highly significant (p <0.01) anthelmintic activity for at least 28 days against a newly acquired infection with Dictyocaulus viviparus (>99% efficacy).
