In vitro anthelmintic activity of plant extracts against Teladorsagia circumcincta and its relationship with total phenols

Trabajo presentado al 12th European Multicolloquium of Parasitology (EMOP). Turku, (Finland), 20-24 julio 2016.The aim of this work was to determine the ovicidal effect of different plant extracts against the gastrointestinal nematode Teladorsagia circumcincta by the egg hatch assay (EHA). The EHA was performed with 200 µl of water containing 100-150 eggs and 200 µl of the plant extract at a final concentrations of 50, 25, 12.5, 6.25, 3.1, 1.5 and 0.75 mg/ml. After 48 hours at 24°C the hatching percentage was calculated. The extracts with an inhibition >95% at a dose of 50 mg/ml were the following ones: Aesculus hippocastanum, Chelidonium majus, Elettaria cardamomum, Isatis tinctoria, Jasminum polyanthum and Sisymbrium irio; and with an inhibition
