[Mycosis of the foot in people over 40].

Some aspects of the ecology of the human foot in the stage of senescence have been studied. Systematically 200 hospitalized patients, chosen at random, between the ages of 40 and 96 years were examined. The following was observed: 1.) 133 patients (66,5%) presented lesions suspected as dermatomycoses. 2.) 67 patients (33,5%) were free from clinical lesions. 42 (31,5%) positive direct examinations were obtained from the first group and 8 (11,8%) from the second one. In culture were isolated different strains of Dermatophytes obtained from 50 patients as follows: a) From digital fold scales: Trichophyton mentagrophytes: 26 (v. granulosa: 9. v. gypsea: 16, v nivea: 1). Trichophyton rubrum: 18, Epidermophyton floccosum: 1. b) From toe nails: Trichophyton mentagrophytes v. granulosa: 3, Trichophyton rubrum: 7. c) From the sole: Trichophyton rubrum: 1. A series of fungi supposed contaminants were isolated among which because of frequency the following are specified: Aspergillus sp., Penicillium sp., Cephalosporium sp., Fusarium sp., some yeast and some Demataceae.
