Mouse Response

• Host Strain: BALB/c, C3H/HeJ, and C57BL/6
• Vaccination Protocol: Two shots of DNA/mouse (1 /Ag/shot) were delivered with helium at 200 psi via the Helios Gene Gun to the shaven abdominal skin of 10 male mice of each strain, BALB/c, C57BL/6, C3H/HeJ. The mice received a booster once 14 days later with the same dose of DNA. In some experiments, pregnant mice of each strain were vaccinated immediately before mating and a booster was given 2 weeks later (Chang et al., 1998).
• Challenge Protocol: Six months after second vaccination, groups of pcDNAIE180 immunized mice were challenged intraperitoneally with a precalibrated mouse acute lethal dose of wild-type PrV-Ka TK+ (15 plaque-forming units (PFU)/g of body weight). The challenged mice were observed three times daily for clinical signs, and percent survival was assessed within 4 to 5 days postchallenge (Chang et al., 1998).
• Efficacy: Seven months after immunization with pcDNAIE180, an overall 25% of BALB/c, C3H/HeJ, and C57BL/6 mice receiving a lethal PrV challenge were protected (Chang et al., 1998).
