WebThe dermatophytes are referred to as zoophilic, anthropophilic, or geophilic, depending on whether their primary source is an animal, human, or soil, respectively. The taxonomy of these fungi is complicated by the fact that most clinical isolates are imperfect fungi (organisms that do not produce sexual structures in culture). WebDermatophytes are keratinolytic fungi whose phylogeny is greatly influenced by ecology. The geophilic species generally form the basal clades and among these sexual reproduction is commonly observed. While only two species have a homothallic nature, the majority of the geophilic dermatophytes are heterothallic, which might indicate that the ...
