[Micromorphology of Trichophyton verrucosum]

Using 6 samples of pathologically altered epidermis of guinea pigs and cattle, chosen strains Trichophyton verrucosum (6 strains) and the two layer method of inoculation on a classic Sabouraud's medium, arthropogenesis of the fungus was investigated. The authors described successive stages of the developmental cycle of T. verrucosum and they found that in all cases the process of arthropogenesis was very similar irrespective of the source of the material used for inoculation. Using various modifications of Sabouraud's medium and a rice medium microscopic examinations revealed in the examined strains of T. verrucosum the presence of chlamydospores (Sabouraud's medium without sugar) macroconidia (rice medium) and spiral forms (Sabouraud's medium with gluconic acid or natrium sulphite) analogical to the forms noted in Trichophyton mentagrophytes.
