Antimycotic effects of some antibiotics on the growth of some dermatophytes and other keratin degrading fungi.

Four antibiotics have been tested against the growth of some dermatophytes and keratin degrading fungi. A gradual decrease in growth was observed with increase in concentration of all antibiotics. All, but griseofulvin observed to inhibit > 50% mycelial weight even at a lower concentration of 50 ppm. Azole derivatives were most toxic to the growth of M. gypseum at all concentrations, whereas, to that of C. tropicum at above 100 ppm. Mycostatin was the most toxic antibiotic to the growth of M. gypsea at all concentrations.
