^aData for 1995 to 2000 are cumulative published (4) and unpublished data excluding pediatric isolates.

^bCefotaxime and ceftriaxone results were calculated by using meningeal breakpoints (≤1, 2, and ≥4 μg/ml) prior to implementation of 2002 NCCLS breakpoint changes for nonmeningeal isolates (11).
