Minimum inhibitory concentration of liposomes

In the conventional broth microdilution assay, the optical density (OD) of drug dilutions, inoculated with microorganisms after sufficient incubation is taken into consideration, which correlates with the most metabolically active cells in the mid log phase of growth. The particles present in the liposomes and other particulate solutions interfere with the OD measurement and produce an erratic result. Resazurin method is more reliable and realistic as it depends on metabolic activity of cells rather than OD of particulate matter present in the samples.
