Title

INHIBITORY EFFECTS OF AQUEOUS ONION AND GARLIC EXTRACTS ON GROWTH AND KERATINASE ACTIVITY IN TRICHOPHYTON MENTAGROPHYTES

Pages

  113-118

Abstract

 The effect of ONION and GARLIC extracts on fungal growth and keratinolytic activity was ‎studied in TRICHOPHYTON MENTAGROPHYTES as one of the major etiologic agents of ‎human and animal DERMATOPHYTOSIS in Iran and other parts of the world. In order to ‎find out the best KERATINASE producer for further steps, culture conditions for 30 strains ‎of T. mentagrophytes isolated from human DERMATOPHYTOSIS were optimized on ‎specific solid and liquid media. All of the isolates produced the enzyme on both ‎selective culture media. The maximum keratinolytic activity at submerged cultivation ‎was reported for cultures of T. mentagrophytes isolate No. 1 grown for a 12-day ‎period at 32°C. Extracellular KERATINASE activity was in the range of 0.28 to 2.18 u/mg ‎protein in different isolates at predetermined optimal conditions. The growth of T. ‎mentagrophytes isolate No. 1 was inhibited in the presence of various concentrations ‎of ONION and GARLIC extracts. This inhibition reached to a maximum of 100% for both ‎extracts at 10% v/v concentrations. KERATINASE synthesis was also inhibited by two ‎extracts as a dose-dependent manner with maximums about 58.54 and 71.36 percent ‎at 5% concentrations, accordingly. In contrast to the fungal growth, keratinolytic ‎activity was inhibited more by GARLIC as compared with ONION extract. This is the first ‎report on KERATINASE inhibition by these two natural compounds. Since fungal growth ‎and keratinolytic activity are important factors in pathogenesis of the dermatophytes, ‎their inhibition by ONION and GARLIC indicate that these substances may have potential ‎values for treatment of human and animal DERMATOPHYTOSIS‏.‏
