This study was designed to investigate the protective effect of non porin outer membrane proteins (OMPs) of Salmonella typhimurium against salmonellosis. Salmonella typhimurium isolated and microscopic examination, some biochemical tests and API 20E identification had been carried out ,  the  isolated previously from stool of infants suffering from diahrria then the outer membrane non porin proteins (OMPs) of this bacterium was extracted and analyzed by Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). Results of protein profile of the S.
