Fowl typhoid caused by Salmonella Gallinarum is a severe systemic disease of poultry characterized by high mortality, morbidity, reduced egg production and heavy economic losses due to culling of infected flocks. In order to investigate antigenicity and immunogenicity, outer membrane protein C (ompC) of S. Gallinarum was extracted, purified and characterized using SDS - polyacrylamide gel electrophoresis, western immunoblot analysis and enzyme linked immunosorbent assay. All the strains of S. Gallinarum tested showed presence of 39 kDa molecular weight ompC protein. Western blots revealed high intensity of reactivity of the ompC to anti-rabbit ompC sera as well as to sera from chickens infected with S. Gallinarum. The ompC protein (39 kDa) of S. Gallinarum effectively induces an immune response and this protein may have a potential for development of diagnostics as well as subunit vaccine.
