Summary

Abstract

ABSTRACTStock solutions of telithromycin, ABT-773, azithromycin, clarithromycin, erythromycin, roxithromycin and dirithromycin were each prepared with eight different combinations of solvents and diluents. Broth microdilution trays were then prepared and frozen at −60 ≥C. Standard quality control strains were evaluated periodically during a 12-week storage time. There were no significant changes in MICs with different solvents and diluents. It was concluded that the easiest approach was to dissolve each compound in water with a small volume (< 2.5 μL/mL) of glacial acetic acid added in a dropwise fashion, followed by further dilutions in deionised water.
