the distribution of geophilic dermatophytes in kenyan soils.two hundred and eighty one soil samples from different provinces of kenya were examined for dermatophytes by the hair baiting technique. dermatophytes were recovered from 84 samples. microsporum gypseum constituted 75.8% of the total isolates while keratinomyces ajelloi and m. cookei formed 21% and 3.2%, respectively. the distribution of the dermatophytes was influences by soil ph, being more prevalent in acidic than in alkaline soils.197829226

ultrastructure of ascosporogenesis in nannizzia gypsea.ascosporogenesis in nannizzia gypsea was studied by electron microscopy. development of ascospores began with the formation of an ascus vesicle composed of two paired unit membranes. myelin figures consisting of coiled or concentric membranes were regularly connected with the growing ascus vesicle. both the ascus vesicle and the myelin figures possessed an electron-dense line between paired membranes, and both were stained by the periodic acid-silver methenamine technique. invagination of the as ...19751126919
saprophytic occurrence of trichophyton mentagrophytes and microsporum gypseum in the coats of healthy laboratory animals. (preliminary report).a group of 199 healthy laboratory animals, comprising 63 guinea pigs; 58 white mice. 47 rats and 31 rabbits, was sampled for the presence of pathogenic dermatophytes. t. mentagrophytes, var. granulare, was isolated in 10% (5-guinea pigs, 6 mice, 6 rats and 2 rabbits) and m. gypseum was found in 7 animals (3 guinea pigs, 3 mice and one rat). no ringworm lesions were observed in the respective animals. this is the first report on such findings in israel.19751143311
