Infection Control: Correctly identifying antibiotic-resistant bacteria helps in implementing effective infection control measures. 2. Patient Care: Ensures that patients receive the most effective antibiotic therapy, thereby reducing recovery time and complications. 3. Antibiotic Stewardship: Helps in promoting the appropriate use of antibiotics, which is essential to combat antibiotic resistance.
