The fungistatic activities of vitamin K on dermatophytes

Summary and conclusions Four commercial preparations of vitamin K were evaluated for their fungistatic activities on the following dermatophytes:Microsporum canis, Epidermophyton floccosum, Trichophyton mentagrophytes, andTrichophyton Schönleinii.Table 1 lists the maximum nonfungistatic and the minimum fungistatic concentrations of each vitamin K.The fungistatic activities of the vitamins K are higher in the liquid than in the solid medium.VitaminIV was the most active on all the dermatophytes in both, the solid and the liquid medium. The fungistatic activities of the other vitamins K vary, in each medium, according to the dermatophyte. Sodium bisulfite decreases the fungistatic activities of vitamin K.Epidermophyton floccosum was the most sensitive to all the vitamins K used.
