Anthelmintic activity of Artemisia vestita Wall ex DC. and Artemisia maritima L. against Haemonchus contortus from sheep.

Abstract Current study was designed to evaluate in vivo and in vitro anthelminticactivity of Artemisiavestita Wall ex DC. and Artemisia maritimaL. against Haemonchus contortusin comparison with ivermectinto investigate the effect of plant extracts on survival of infective L 3 and adults under in vitro condition. Plant extracts were given to H. contortus infected sheep orally and it was infected with L 3 stage of H. contortus at dose of 5000 larvae/sheep. Total of 25–30 larvae were incubated with plant extracts in PBS alone and ivermectinat different concentration used as positive control. It was recorded that there is a significant decrease in fecal egg count (FEC) after post-treatment period for both plants. The highest fecal egg count reduction for A. vestita was 87.2% at 100 mg/kg while for A. maritima it was 84.5% on day 28 post-treatment. Investigated extracts indicated significant activity against larvae and adult worms.
