Cutaneous mycoses are among the most common
fungal infections and are mostly caused by filamentous
keratinophilic fungi that use keratin as a
nutrient during skin, hair, and nail infection. These
fungi are called dermatophytes and are classified into
three genera, Trichophyton, Microsporum and
Epidermophyton, based on the formation and morphology
of their conidia (structures of asexual reproduction).
In addition, species of dermatophytes are
divided into zoophilic, geophilic or anthropophilic,
depending on their primary habitat (animals, soil or
humans, respectively). Zoophilic species are responsible
for about 30% of human dermatophytoses and
they often provoke acute inflammation; anthropophilic
species represent about 70% of infections on
these hosts, causing a chronic infection of slow progression,
suggesting that the fungus has adapted to
the human host. So far, about 30 species of dermatophytes
have been identified among human pathogens.
