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.
