Mouse Response

• Persistence: A fliC/guaB mutant is attenuated in mice (Adriaensen et al., 2007).
• Efficacy: A fliC/guaB mutant induces significant protection in mice from challenge with wild type S. enterica (Adriaensen et al., 2007).
• Host IgG response
  • Description: Fifty-four days following initial oral immunization of BALB/c mice with approximately 108 CFU per mouse of, respectively, the S. enterica serovar Enteritidis ΔguaB and S. enterica serovar Enteritidis ΔguaB ΔfliC mutants, blood samples were collected from the tail arteries of five mice. Comparison between sera of mice immunized with S. enterica serovar Enteritidis ΔguaB and mice immunized with S. enterica serovar Enteritidis ΔguaB ΔfliC showed that, in both cases, comparable anti-LPS serum IgG responses were elicited (Adriaensen et al., 2007).
