Abstract

|
With Giemsa stain in Sorensen´s buffer (pH 7. 0), the nuclei of hyphae from the cultures of Trichophyton mentagrophytes were successfully. demonstrated. In resting stage they were round or elliptical, condensed nuclei, each of which was situated. in the middle of a hyphal body and. Arranged in a linear manner along￢the hyphal length. They were divided by atypical mitosis and with asynchronism. In, early divisional stage they took the shapes of irregular, annular or rosette-￢like and thready forms in succession. In intermediate stage each nucleus had 2´ pairs, of chromosomes (Each pair had 2 parallel, short bars.) connected one another by thin filaments, and each chromosome soon. split longitudinally into 2 sister￢chromatids. In terminal stage the disjunction of chromatids occurred asynchro￢nously and -its detailed process was, an obscure one. The telophase nuclei were condensed, reduced in, volume, and arranged at shorter intervals than in the resting stage. Thee structures suggesting the. Formation of septa were also observable in the dividing stage.
