title: [Research of keratinophiles in the soil and their effects on human cutaneous pathology in the Lyons area].
abstract: Between 1967 and 1977, the systematic research of keratinophiles of the ground in a radius of 30--50 km around Lyon, has shown the ubiquitarian predominance of Microsporum nanum, which is probably the most ancient occupant of the ground. The most intensive areas of human and animal occupation in the Rhodanian tract show the predominance of Microsporum gypseum, which is scarcely found in man. Sporadic localizations, tightly limites, bound to cirulcation axes and international gathering, let us detect Microsporum cookei, Trichophyton verrucosum, Trichophyton mentagrophytes, Chrysosporium keratinophilum, and Keratinomyces ajelloi. However, in the last years, a progressive extension of recently imported kinds and a decrease in native kinds appears to have occurred.
