FIG. 1.

Antimicrobial susceptibility of 859 representative ETEC diarrhea-associated strains from Egyptian children under 3 years of age. The graph on the left indicates the susceptibilities of all isolates to different antibiotics, including ampicillin (AMP), tetracycline (TET), trimethoprim-sulfamethoxazole (SXT), naladixic acid (NA), ciprofloxacin (CIP), ceftriaxone (CRO), and aztreonam (ATM). The smaller graphs to the right show the changes in susceptibility to SXT and tetracycline by year (for 1995, n = 271; for 1996, n = 264; for 1997, n = 324) over the 3-year course of the study.
