Kyokuto supplies various drug susceptibility test kits that are compatible with CLSI. To achieve consistent quality, strict quality-control examinations using the ATCC strain are conducted on these products. The antifungal susceptibility testing for yeast (ASTY) uses a unique method of MIC determination: various forms of oxidoreductase are produced by a yeast-trigger redox reaction with resazurin, and coloration of the culture medium indicates MIC. We also supply broth medium and test plates for drug susceptibility testing of general and anaerobic microorganisms or yeast.
