a The maximum concentration tested was 250 µg mL−1. Gentamicin was used as control antibiotic (concentration 10 µg mL−1). Tests were performed in triplicate. - No inhibition at the concentration tested. >250 indicates that there was sensitivity, but the concentration should be higher than 250 µg mL−1 for a count of fewer than 300 colonies.
