We investigated the safety, immunogenicity and protectivity of mix-crude outer membrane protein (cOMP) vaccine against salmonellosis in animals. The mix-cOMP vaccine was extracted from Salmonella enterica serovar Typhimurium (ST) and Salmonella enterica serovar Enteritidis (SE) and Salmonella enterica serovar Braenderup (SB) isolated from pigs. The mix-cOMP vaccine gave significantly higher antibody response than ST-bacterin and ST-cOMP vaccine in guinea pigs. The survival rates of mix-cOMP vaccinated groups showed significantly higher (100%) than those (0-20%) of unvaccinated control group, challenged with 3 species of Salmonella (ST, SE and SB) in mice. Vaccinated groups in pigs showed reduction of clinical signs, increase of average weight gains, decrease of bacterial recovery rates, compared with unvaccinated groups. Especially, the survival rates (100%) of vaccinated groups in chickens showed higher than that (0%) of unvaccinated group. Based on these results, we suggest that the mix-cOMP Salmonella vaccine developed in this study will be effective for the protection against Salmonellosis caused by the various serotypes Salmonella species in animals.
