Anthelmintic activity of ginger, curcumin, and praziquentel against Raillietina cesticillus (in vitro and in vivo).

Abstract

This work evaluates the anthelminitic activity of ginger and curcumin on the cestode Raillietina cesticillus. Live parasites were collected from intestine of naturally infected chickens in PBS 0.9 % and then incubated at 37 °C in media containing ginger extract at three different concentrations (125, 250, and 500 mg); every concentration was dissolved in 10 ml media. The curcumin extract was used at three different concentrations (250, 500, and 1000 mg); each was dissolved in 10 ml media. Praziquantel at a concentration of 600 mg was added to 10 ml media. A control one without extract was reported. Regression of worms increased gradually in all concentrations. At 500 mg ginger (50 ± 0 %), worms were regressed at 48 h post-exposure (h.p.e.). Also (50 ± 1.8 %), worms were regressed at 1000 mg curcumin at the same time. On the other hand, praziquantel showed the highest regression (65 ± 2.3 %). The extract efficacy was exhibit as concentration-time-dependent mainly at higher concentrations used after 48 h. In vivo effects of ginger and curcumin were lower than those in vitro.
