Popis: | Schistosomiasis is a neglected tropical parasitic disease which has been controlled by praziquantel for many decades; however, reemergence of praziquantel resistant strains has been a continuous threat. Therefore, the development of reliable antischistosomal vaccine is significantly demanded for optimal control. In the present study, comparison among Schistosoma haematobium, Schsitosoma mansoni and Pygidiopsis genata crude antigens was carried out by Sodium dodecyl sulphate polyacrylamide gel electrophoresis. Hyperimmunization of rabbits with tested parasites’ crude antigens was done to obtain hyperimmune sera. Western blotting was applied to show cross reactivity between parasites’ crude antigens and either homologous or heterologous sera. Although there was no cross reaction between P. genata crude antigens and sera of both Schistosoma species and vice versa; it is supposed that the immunogenic band at 79 kDa might develop cross reactivity with Schistosma spp. SEA fractionation if used in future studies. |
