FIG. 1.

Pharmacodynamics of gatifloxacin and levofloxacin against S. pneumoniae 256 (A), S. pneumoniae 257 (B), S. pneumoniae 313 (C), and S. pneumoniae 314 (D). Each datum point represents the number of viable bacteria (log₁₀ CFU per milliliter) for single experiments, and numbers to the right of the datum lines represent the actual AUC/MIC ratios to which the S. pneumoniae strains were exposed in each experiment. LEV, pharmacodynamics of the levofloxacin comparative control in each experiment.
