Abstract
Schistosomiasis is the second commonest parasitic disease worldwide. It is responsible for thousands of deaths per year in addition to the associating serious morbidities that burden both individuals and communities. To date, the main preventive measure of infection is mass treatment with praziquantel. it carries the risk of reinfection and rising resistance which makes the discovery of an effective vaccine an urgent necessity. The present study evaluated E. camaldulensis killed cercariae immunogen (KCI) as a candidate vaccine for experimental schistosomiasis mansoni and to detect the possible immunological mechanisms of action of this immunogen. The KCI caused a significant reduction of both schistosomula and adult worm counts with subsequent ova count reduction. Hepatic granulomas were reduced in number or size. Also, levels of IgG, IgG1 & IgG2a as well as INF-γ & IL-10 fluctuated larger than in natural infection.
