RYBNIKÁŘ A., HEJTMÁNEK M., WEIGL E. (2003): Survival rate of Trichophyton equinum and T. verrucosum mutants at lyophilisation. [lyophilisation, dermatophytes, mutants] Czech Mycology 55(3-4): 273-276 (published: 22nd December, 2003)
abstract
Trichophyton equinum and T. verrucosum mutants were prepared from monoconidial wild-type strains by induction with ultraviolet radiation. The percentage of elements surviving at lyophilisation was approximately the same as or higher than that of relativ ewild-type strain with four of twelve T. equinum mutants and five of nine T. verrucosum mutants. With remaining eight T. equinum mutants and four T. verrucosum mutants the ability to survive at lyophilisation was lower in comparison with the wild-type strains.
RYBNIKÁŘ A., DITRICH O., PYTELA F. (1983): Lyophilization of some cultures of dermatophytes. Česká Mykologie 37(2): 93-98 (published: 1983)
abstract
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.
