Molecular Characterization of Extended-Spectrum β-Lactamase Isolated from Egyptian Patients with Community- and Hospital-Acquired Urinary Tract Infection.

Extended-spectrum β-lactamases (ESβLs) pose a serious problem in the treatment of urinary tract infections (UTIs). The ESβL-producing organism is an expanding global health problem. Therefore, screening for ESβL, detection of their drug-resistance pattern, and molecular characterization should be a continuous process.
