The effect of lyophilization on the viability of germs of eleven species of dermatophytic fungi was studied. Cultures composed mainly of microconidia retained viability, while those composed of hyphae, macroconidia, and chlamydospores showed reduced viability. No changes in morphology or virulence were observed. For Trichophyton verrucosum, viability dropped by 20–78% after five years of storage at 4°C.
