Mouse Response

• Host Strain: BALB/c
• Vaccination Protocol: Six- to eight-week-old female BALB/c mice were immunized via i.p. route with 1 ml of PBS containing 10^3 CFU of ΔpmrG-HM-D strain per mouse and 10 μg of DNA vaccine plasmid in 50 μl volume of PBS in cohort of five mice. Booster doses were given on 7th and 14th day. Placebo control mice were injected with 10^3 CFU of ΔpmrG-HM-D strain per mouse and 10 μg of empty pCI-TPA vector (Nagarajan et al., 2009).
• Challenge Protocol: 21 days after immunization, mice were challenged with 10^7 CFU/mouse of WT Salmonella orally (Nagarajan et al., 2009).
• Efficacy: SopB DNA vaccine immunization reduced the bacterial burden of organs by about 5-fold on day 4 and day 8 after challenge with virulent Salmonella and proved to be a more efficient vaccination strategy than live attenuated bacteria alone (Nagarajan et al., 2009).
