What are the Advantages of Using Mannitol Salt Agar?
MSA offers several advantages: 1. Selectivity: The high salt concentration inhibits non-halophilic bacteria, ensuring that only staphylococci grow. 2. Differentiation: The mannitol and phenol red combination allows for easy differentiation between S. aureus and other staphylococci. 3. Cost-Effectiveness: It is relatively inexpensive and easy to prepare. 4. Rapid Results: It provides results within 24-48 hours, which is crucial for timely epidemiological interventions.
