MAIN EDUCATIONAL POINTS from M151-1
- Reporting quantification on urine culture provides important clinical information to the clinician.
- E. coli is the most common pathogen causing uncomplicated urinary tract infections (UTIs). Isolates are not infrequently resistant to first-line (e.g., SXT, nitrofurantoin) and second-line (e.g., ciprofloxacin, amoxicillin-clavulanate) antimicrobial agents; performing antimicrobial susceptibility testing is essential to ensure patients receive adequate therapy.
