Hi Suresh, can you give me a few more details? You ran an MIC curve against C. albicans using fluconazole as a control? What range of drug did you use?
As you have mentioned that fluconazole doesn't show any MIC. So, can you give the standard antimycobial dose value for Candida albicans obtained in your results.
We really need more detailed information. 30 ug...per what volume? Were they 1:1 dilutions in your dilution series? Did your positive, vehicle control grow well?
C. albicans are group of microbe (Yeast) some of which causes skin diseases. However, some other strains are found in starter of traditional fermentation processes and are not harmful. C. albicans could certainly be used as Positive control in bioassay of antifungal activity.
