RESUMO

The porin, an outer membrane protein of Salmonella typhimurium, was found to be a suitable antigen for eliciting delayed-type hypersensitivity in mouse salmonellosis. Histological examination of the reaction site revealed that the porin was superior to other antigenic preparations in eliciting a typical delayed-type hypersensitivity reaction consisting of mononuclear cell infiltration without polymorphonuclear cell contamination. This study indicates the importance of using a suitable protein antigen from S. typhi for human application.
