aTmp-smx, trimethoprim-sulfamethoxazole; ABC, Active Bacterial Core Surveillance; TRUST, Tracking Resistance in the United States Today; RESP, Respiratory Surveillance Program.

bIf the surveillance overlapped two calendar years while covering one respiratory season, data were classified by the latter year. For example, isolates collected from October 1999 to April 2000 were labeled as year 2000 data.

cData for only invasive isolates (ABC); respiratory and invasive isolates (Doern, TRUST, NC); only respiratory isolates (RESP)

d1997–1999 TRUST data are for clarithromycin.

e1997 ABC data are for ofloxacin; all Doern data are for ciprofloxacin.
