ABSTRACT
Objective: To evaluate the in vitro and in vivo effect of the Algerian propolis ethanolic extract (EEP) against Echinococcus granulosus (E. granulosus) infection. Methods: In vitro scolicidal activity of EEP was investigated on the protoscolices of hydatid cyst. This in vitro study was conducted by using an in vivo assay. BALB/c mice were inoculated with E. granulosus and treated with propolis for three months. Hydatid cysts development was assessed. Nitric oxide (NO), tumor necrosis factor alpha (TNF-α) production and inducible NO synthase, NF-κB, and TNF-α spleen expression were estimated by Griess method and immunofluorescence respectively. Results: Our study revealed that EEP has a high scolicidal activity against E. granulosus. Oral administration of EEP decreased TNF-α, NF-κB and inducible NO synthase expression in the spleen tissues in the CE+EEP group, in comparison with the CE group. Concomitantly, EEP treatment caused an important systemic decrease in NO and TNF-α levels. These findings are associated with the reduction of CE development. Conclusions: This is the first report demonstrating with interest the antihydatic and immunomodulatory effects of the Algerian EEP, suggesting its therapeutic potential for the hydatid disease treatment.
