- Preparation: Dom+ Scs+ Hly+ organisms of strain L3 were streaked on two BG-20 agar plates and incubated at 37°C. Ten Dom+ Scs+ Hly- colonies (0.5 to 0.7mm in diameter) grown on each plate were subcultured 10 times under the same culture conditions. Finally, four mutant strains showing the Dom+ Scs+ Hly -phenotype and lacking DNT- producing ability were obtained (Nagano et al., 1988).
- Immunization Route: intranasal immunization

Host Response |
Guinea pig Response
- Efficacy: Most of the guinea pigs inoculated intranasally or intramuscularly with 2.3 x 10^7 or 2.3 x 10^8 viable cells of strain B-42 produced serum agglutination antibodies at 3 week after the inoculation, and most of them survived intranasal challenge with strain L3 (770 x LD50) during observation period (Nagano et al., 1988).
