title: Dermatophytes in Portugal (1972-1981).
abstract: For the years 1972-1981, 7 333 isolates of dermatophytes belonging to 14 species were obtained from glabrous skin (32%), feet (28%), groin (19%), scalp (8%), toenails (7%), fingernails (3%) and beard (1%). T. rubrum represented 50% of all the isolates and was the most frequent species on glabrous skin, groin and nails. T. mentagrophytes (24%) was mainly obtained from the feet, E. floccosum (9%) from the groin and T. megninii (4%) from uncovered areas of the skin, fingernail and beard. These 4 species predominated in men. M. canis was the commonest agent on the scalp and in children up to 11 years. T. violaceum, previously the main cause of tinea capitis, and T. tonsurans have been decreasing for the period of this study, just as T. schoenleinii for the years 1962-71. The rising prevalence of T. rubrum was observed since 1962. In the whole it seems stable after 1969, but the analysis of the main sites involved shows that in the glabrous skin this species increased from 1962 to 1974; in the groin it was gone up from 30% during 1962-1965, to 64% in the years 1969-1971; in the feet the evolution was slower and only in 1980 T. rubrum became more frequent than T. mentagrophytes. The increase in certain species, whereas others become rare, lacks a satisfactory explanation.
