Mouse Response

• Host Strain: BALB/c
• Vaccination Protocol: Mice were injected subcutaneously (s.c.) with 30 lg rVagHis in CFA and boostered with 30 lg rVagHis in ICFA four weeks later. Control mice were treated similarily with CFA or ICFA, but lacking rVagHis (Schmidt et al., 1999).
• Challenge Protocol: Mice were challenged intraperitoneally (i.p.) with 0.5 ml bacterial suspension containing either 3x10^3 cells of Y. enterocolitica 0:8 strain NCTC10938 or 4x10^4 cells of Y. pseudotuberculosis strain YPlll/pIB102. Survival of mice was monitored over 2 months (Schmidt et al., 1999).
• Efficacy: Mice actively immunized using a recombinant V antigen (rVagHis, encoded by lcrV gene) of Y. enterocolitica were completely protected against challenge with both, Y. enterocolitica 0:8 and Y. pseudotuberculosis serotype III (Schmidt et al., 1999).
