摘要

Outer membrane proteins (OMP) extracted from both smooth (C5) and rough (Rb2) strains of Salmonella typhimurium were able to induce protective immunity to salmonellosis. The OMP-induced protection lasted for at least 6 months. The antibody level was estimated by passive hemagglutination. In the C5 OMP-immunized mice, antibodies to both proteins and lipopolysaccharide were detected. On the other hand, in the Rb2 OMP-immunized mice, antiprotein but not antilipopolysaccharide antibodies were detected. Delayed-type hypersensitivity appeared as early as the second week after immunization with OMP and persisted through the fourth week.
