Epidemiology of dermatophytic infections in Rome, Italy: a retrospective study from 2002 to 2004.

In the present study, we determined the incidence of dermatophyte species causing superficial mycoses among outpatients referred to the Department of Dermatology of the "La Sapienza" University of Rome between 2002 and 2004. Of the 3160 subjects studied, 1275 (40.3%) were positive for fungal infection, but only 252 (19.7%) of these had infections caused by dermatophytes. The dermatophyte most frequently isolated was Microsporum canis. Our epidemiological data were compared with those obtained previously by other authors in the same geographic area. For the first time we described an inversion of the T. rubrum/T. mentagrophytes ratio, the latter being more frequently encountered. We also observed the emergence of M. audouinii.
