Funghi dermatofiti presenti in terreno di tane di marmotta (Marmota marmota) dell'Arco Alpino Occidentale. Dermatophytes in alpine marmots' (Marmota marmota) burrows soil from western Alps [Dermatophytes du sol des terriers de marmotte (M. marmota) des Alpes occidentales].

Résumé

A survey was performed to define the distribution of dermatophytes fungi in a mountain environment (Italian Western AIps). The results obtained by examining soil samples taken from marmots' habitat are shown. 110 samples taken from the soil before the entrance of inhabitated burrows and 40 taken far from the colonized areas and used as control were collected. The samples were examined by Vanbreuse-ghems' method (horse hairs used as keratinic baits on wet soil, for dermatophytes growth) modified by grinding horse-hairs for a more homogeneous distribution of keratin. The following dermatophytes fungi were identified by Rebell and Taplins' keys : Microsporum canis, M. gypseum, M. cookei, Trichophyton mentagrophytes, Trichophyton spp. All species identified were recovered in soil samples collected from marmots' burrows. No dermatophytes were found by examining the control samples
