TABLE 2.
SBA titers following immunization with rPorA or MenC-PS against strains BZ198 (B:NT:P1.7-2,4) (following rPorA immunization) or C11 (C:16:P1.7,1) (following MenC immunization)
| Adjuvant | Titer for antigena: |
|
|---|---|---|
| PorA P1.7-2,4 | MenC-PS | |
| H44/76-lpxL1 nOMVs | 1:32 | 1:32 |
| H44/76-lgtB-lpxL1 nOMVs | 1:128 | 1:64 |
| MPL | 1:128 | 1:128 |
| Aluminum hydroxide | <1:4 | <1:4 |

Titers represent the reciprocal of the last dilution at which ≥50% killing was achieved. Serum samples whose first dilution yielded <50% killing of the number of bacteria used were assigned a titer of <1:4.
