Abstract Background: The rapid antimicrobial susceptibility testing (AST) performed on urine samples would guide the adequate choice of antibiotics for obtaining better treatment outcomes in patients. Our study aimed to evaluate the performance of the modified-EUCAST (European Committee on Antimicrobial Susceptibility Testing) rapid direct AST on urine samples. Methods: From >2,000 urine samples, a total of 128 urine samples containing bacterial counts of ≥2 × 104 CFU/mL with a uniform

Methods: From >2,000 urine samples, a total of 128 urine samples containing bacterial counts of ≥2 × 104 CFU/mL with a uniform bacterial shape were initially included based on flow cytometry (Sysmex UF-1000i, Japan) and Gram staining, respectively. A total of 103 samples
