Host Response |
Mouse Response
- Host age: New born
- Vaccination Protocol: Mice were immunized with 50μl of one-tenth dose of an adult mouse of DTP at day 5 (or day 12 as specified) or 10^5 CFU of BCG or rBCG-S1PT on day 5 according to different regimens (Nascimento et al., 2008).
- Vaccine Immune Response Type: VO_0003057
- Challenge Protocol: Mice were subjected to intracerebral inoculation with a lethal dose of B. pertussis with approximately 3 x 10^4, 3 x 10^5, or 9 x 10^5 CFU (in 30μl) on day 21 after birth.
- Efficacy: A single dose of rBCG-S1PT at day 5 led to a 100% survival of mice, and even at an extremely high challenge dose (300 times the lethal adult dose) rBCG-S1PT still induced 50% survival of neonate-immunized mice. Mice immunized with BCG alone experienced a protective effect of 80%, however at a higher challenge dose, this effect was reduced to 50%. Mice immunized with DTP showed no protection (Nascimento et al., 2008).
