Abstract:
A mating study was performed by crossing 333 isolates of Trichophyton mentugrophytes with+and tester strains of Arthroderma vanbreuseghemii, A. benhamiae and A. simit from January 1980 to December 1983 Three hundred and thiirteen were compatible with A. vanbreuseghemri consisting of 167 of+type and 146 of type and twenty were indeterminate. The cleistothecia formed by crossing the isolates with tester strains of A. vanbreaseghemii were fewer in number and smaller in size than those of tester strains. The sexual dogeneration was observed in all of the isolates compared with tester strains. The colonial morphological features of the isolates of T. mentagrophytes were observed as 24p isolates of the granulosum-asteroides form, 66 of the powdery form and 7 of the downy form on 1/10 Sabouraud agar with salts in culture. The mat- ing type showed the higher type in the granulosumasteroides forrn and + type in the powdery and downy forms. The + type increased from 1981 to 1983, and the type showed a marked increase in 1983. The + type was predominant in tinea pedis et unguim and tinea cruris, and type in tinea faciale and tinea manuurn. The + type showed nearly equal incidence in the spring, winter and summer, and the lowest in the autumn, compared to the highest in the winter and the lowest in the summer in the type.
