We compared uropathogen antibiotic susceptibility across age groups of ambulatory
pediatric patients. For Escherichia coli (n=5,099) and other Gram-negative rods (n=626), significant
differences (p<0.05) existed across age groups for ampicillin, cefazolin, and
trimethoprim/sulfamethoxazole susceptibility. In E. coli, differences in
trimethoprim/sulfamethoxazole susceptibility varied from 79% in children under 2 to 88%...
