IFNG and infection: Concentration of IFN-γ in culture supernatants of splenocytes upon in vitro stimulation. Clearance of challenge infection with B. abortus 2308 and B. melitensis 16 M measure as CFU in spleen in mice previously vaccinated with mutant strains. Development of IgG2a:RB51SOD, developed antibodies to SODRB51WboA, develop to the O-side chain RB51SOD/WboA, develop to SOD and the O-side chain.
