Effect of aqueous extracts of the leaves of Teucrium polium; the fruits of Citrus aurantifolia and Capsicum annum on the viability of the protoscoleces of Echinococcus granulosus of sheep origin in vitro
Abstract
ABSTRACT Results of the present study revealed significant effect of aqueous extracts of the leaves of Teucrium polium; the fruits of Citrus aurantifolia and Capsicum annum at the concentrations 5, 10, 15, 20, 25 and 30 mg/ml for T. polium ; the concentrations 2.5, 5, 7.5, 10, 12.5 and 15 mg/ml, for C. aurantifolia and the concentrations 1, 1.25, 1.5, 1.75, 2 and 2.25 mg/ml, for C. annum on the viability of the protoscoleces of Echinococcus granulosus of sheep origin in vitro. Hence, the concentration 30 mg/ml for T. polium causes death of all protoscoleces in 30 minutes, by the same token, the concentration 15 mg/ml of C. aurantifolia causes the same effect in 45 minutes, while the concentration 2.5 mg/ml of C. annum reduces the viability of the protoscoleces to 4.0% in 60 minutes.
