Effective therapeutic options are needed for community-onset urinary tract infections due to Escherichia coli strains that produce CTX-M extended-spectrum β-lactamases. We examined 46 urinary isolates producing CTX-M against several oral or long-acting parenteral antimicrobial agents. Approximately 90% were susceptible to fosfomycin and to a combination of cefdinir plus amoxicillin-clavulanate. All were susceptible to ertapenem.
