This study was designed to investigate the protective effect of non porin outer membrane proteins (OMPs) of Salmonella typhimurium and O-specific polysaccharide (OSP) of E.coli as conjugated vaccine against salmonellosis. One hundred urine samples were collected from patients with UTI. E.coli was isolated, identified by performing some biochemical tests and API   E system and O-specific polysaccharide was extracted by phenol hot water method. The outer membrane proteins  (OMPs) of S.

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.
