The faster, easier way to work with standards. Furthermore, previous studies have demonstrated a much higher interlaboratory variation in MIC results for quality control strains for itraconazole than for flucytosine and fluconazole 6 – 8.
Since the hydrophilic growth medium RPMI-G at pH 7 has been selected for testing in vitro antifungal susceptibility, it was important to describe the lack of proper solubility of this compound. Received Jan 20; Accepted Feb Izo MIC is a guide for 200776-1 clinician to the susceptibility of the organism to the antimicrobial agent and aids treatment decisions. However, preparation of ITC trays for antimicrobial susceptibility testing AST microdilution tests is associated with a significant lack of reproducibility, 207776-1 after freezing and shipping, independent of which dilution method was followed.
