| Individuals acquire permanent immunity to each strain that infects them, but there is no evidence of cross-immunity. Experimental evidence indicates that immunization with one Salmonella serovar can generate cross-immunity against a second serovar if both organisms have the same immunodominant O-antigen on their cell surface (17-19). Individuals acquire permanent immunity to each strain that infects them, but there is no evidence of cross-immunity. |
