FIG. 3.

Growth characteristics of A. baumannii mutant library members with increased serum susceptibility. Shown are the growth characteristics of the wild type (strain 98-37-09) and isogenic mutants in LB medium (solid bars) and human serum (hatched bars), as measured by the OD₆₀₀. All values have been plotted relative to wild-type growth (set at 1.0). Also shown are the growth curves of wild-type (solid boxes), ACJ2 (A1S_2989 mutant; solid diamonds), and ACJ2 harboring pACJ01 (wild-type copy of A1S_2989; open circles) in human serum (inset). Standard deviations are shown (n = 6).
