Bactericidal activity of serum donor 9: survival of arcA mutants Hib1 (arcA::kan) and Hib2 (arcA::tet), repaired arcA mutant Hib3 (arcA*res), and the wild type (wt) in serum from donor 9, expressed in CFU per milliliter. The initial inoculum was 106 CFU/ml. At 135 min, the titer of the arcA mutants fell below the threshold of detection (100 CFU/ml), while the levels of Hib3 and the wild type remained stable.
