Significance of MAR index
The MAR index, or Multiple Antibiotic Resistance Index, is a calculated value used to assess antibiotic resistance in bacterial isolates. A value of 0.2 or lower signals a high risk of resistance, suggesting that the isolates may originate from environments with significant antibiotic exposure. This index plays a critical role in understanding and managing the potential risks associated with antibiotic-resistant bacteria in both clinical and environmental settings.

The concept of MAR index in scientific sources
The MAR index, or Multiple Antibiotic Resistance Index, evaluates bacterial isolates' antibiotic resistance levels and potential origins from high antibiotic exposure environments. A value of ≤ 0.2 indicates a high risk of antibiotic resistance.
