Effect of the alcoholic extract of the germander Basra lemon and red pepper in viability of Echinococcus granulosus protoscoleces of sheep origin in vitro

Abstract

ABSTRACT The results of the present study revealed significant effect of al-coholic 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 caused the death of all protoscoleces in 30, 45, 60 minuets, respectively, the concentration 25 mg/ml caused the same result in 60 minuets, while the concentration 15 mg/ml of C. aurantifolia reduced the viability of the protoscoleces to 10.33% in 60 minutes and the concentration 2.5 mg/ml of C. annum reduced the viability of the protoscoleces to 11.0% in 60 minutes.
