Figure 7.

Serum from immunized guinea pigs has bactericidal activity. Sera from animals immunized with two doses of (A) CVD 1208S, (C) CVD 1213, or (E) CVD 1215 or with two doses of a mixture of CVD 1208S, CVD 1213 and CVD 1215 (B, D and F) was assessed for the ability to kill wild-type strains of S. flexneri. The mean percent bactericidal activity against parental wild-type strains 2457T (A and B), J17B (C and D) and CCH060 (E and F) is shown for each serum dilution tested from immunized guinea pigs. The horizontal dashed line indicates the 50% bactericidal titer.
