Mouse Response

• Host Strain: C57/BL6
• Vaccination Protocol: A total of 50 μg of recombinant protein was mixed with Alum and FCA/FIA, according to the manufacturers’ descriptions, or PBS, in a total volume of 200 μl per dosage. All immunizations and boosters were administered subcutaneously. rDOBV N or rDHFR in Alum, FCA or PBS were administered at day 0. At days 21 and 92, mice were boosted with rDOBV N or rDHFR in Alum, FIA or PBS (Klingstrom et al., 2004).
• Challenge Protocol: At day 118, all mice were challenged with 10 mouse ID50 of DOBV and 21 days later, all mice were sacrificed. Serum, plasma, and EDTA-blood were drawn at the time points indicated below (Klingstrom et al., 2004).
• Efficacy: Study compared the immunogenicity and protective efficacy of recombinant DOBV nucleocapsid protein (rDOBV N, S) given with Alum or Freund's as adjuvant, or PBS, in C57/BL6 mice. Mice receiving rDOBV N with Freund's adjuvant were protected from challenge (75% protected) (Klingstrom et al., 2004).
• Host Il2 response
  • Description: Significantly higher levels of IL-2 producing cells were found in the group given rDOBV N with Alum as compared to the rDHFR vaccinated groups and PBS vaccinated groups. These results were found in mice peripheral blood mononuclear cells (PBMCs) 113 days after vaccination (Klingstrom et al., 2004).

• Host Il4 (interleukin 4) response
  • Description: Significantly higher numbers of IL-4 producing cells were found in the groups given rDOBV N with Freund’s adjuvant as compared to rDOBV N with PBS. These reactions were found in peripheral blood mononuclear cells (PBMCs) 113 days after vaccination (Klingstrom et al., 2004).
