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.
