FIG. 4.

Caspase 1^−/− and WT mice generate similar antibody titers during B. burgdorferi infection. Antibody titers are the reciprocal endpoint positive titers of B. burgdorferi-specific antibody in serum obtained from mice infected for 9 days (A) and 14 days (B). The titers were measured by ELISAs as described in Materials and Methods. Results are representative of three experiments with five mice per group.
