Teleomorphs and mating types in Trichophyton mentagrophytes complex.
In the set of 132 strains of Trichophyton mentagrophytes isolated from humans (129 strains) and animals (3 strains) with dermatophytosis in Czechoslovakia, 41 strains were classified as Arthroderma benhamiae. Out of them, 40 strains were of mating type + and one strain of type -. Ten strains were A. vanbreuseghemii, including 3 strains of mating type + and 7 strains of type -. ⋯ The determination of mating types using the test of sexual stimulation with Arthroderma simii and hybridization test with the reference strains of A. benhamiae and A. vanbreuseghemii gave identical results. No relationships between the variety of anamorphous state (T. mentagrophytes var. mentagrophytes, var. granulosum, var. interdigitale, var. quinckeanum), teleomorph, mating type, localization of dermatophytosis, and pathogenicity for guinea pig were found. The reasons for unequal distribution of mating types in clinical isolates of various dermatophytes are discussed.
