Fig. 3From: Live attenuated Salmonella typhimurium vaccines delivering SaEsxA and SaEsxB via type III secretion system confer protection against Staphylococcus aureus infectionEvaluation of humoral and mucosal immune responses against rSaEsxA and rSaEsxB by ELISA. Mice were immunized with N106, N19 and N20 strains (n = 8/group). SaEsxA and SaEsxB were delivered via SPI-1 T3SS by N19 and N20, respectively. Seven days after the second booster, antigen-specific serum IgG1 and IgG2a (a), as well as fecal sIgA (b) were examinedBack to article page
