Different species of Aspergillus involved in ungual pathologies
AbstractIn recent years non dermatophyte fungi (NDF) are often described as responsible for onychomycosis. The problem related to these fungi concern their identification and treatment. Nowadays a number of Aspergillus were observed in this kind of pathologies but the identification at level of species is frequently omitted. In this work we analysed 26 cases of onychomycosis caused by Aspergillus, belonging to 8 different species. The identification were based on micro- and macro-morphological characteristics; physiological characters; and molecular analysis (B-tubulin gene). 3 species are very interesting: A. perii, a species recently described; A.nominus, never described before in onychomycosis, and A.melleus, likely a new opportunistic fungus involved in medical mycology. Though the identification of these fungi is an additional workload for the laboratory of medical mycology, there is the need to increase the number of identified NDF in order to improve the management of onychomycosis.
