This study was carried out to determine the whole cell protein profiles of Salmonella serovars from chicken, turkey and sheep faeces by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). A total of 34 Salmonella strains were included in the study, 14 of them were isolated from chicken, 14 from turkey and six from sheep. SDS-PAGE was carried out using 12% (w/v) separating and 4% (w/v) stacking gels. The results showed more than 30 protein bands ranging in size from 97 kDa (kilodaltons) to below 14.4 kDa as determined by visual assessment of their approximate molecular masses. Protein bands of 78.1, 51.2, 41.5, 37.3, 35.1, 33.9, 30.7, 27.6, 25.4, and 24 kDa were detected in all Salmonella serovars. Salmonella strains used in this study were closely related and could not be differentiated depending on the whole cell protein profiles using SDS-PAGE.Keywords:
