The agar microdilution method - a new method for antimicrobial susceptibility testing for essential oils and plant extracts

Abstract

In the era of increasing antibiotic resistance high hopes are associated with new drugs of plant origin. However, the lack of standardized and reliable testing methods for assessing antibacterial activity of plant natural products causes impediment to research into this area. This study demonstrated that the agar microdilution method can be used successfully for testing oily and coloured substances.
