Epidemiology of Dermatophytes in Belgium: A 5 Years' Survey.

Dermatophytes are among the most common fungal agents causing superficial skin infections worldwide. Epidemiology of these infections is evolving and variable in every country. This report presents the Belgian epidemiological data regarding the distribution of dermatophytes species isolated by the two national reference centers for mycosis during a period of 5 years (2012-2016). Trichophyton rubrum was the most frequently isolated species, considering all sampling sites (60.3% on average between 2012 and 2016). More precisely, this dermatophyte was the major agent of Tinea unguium and Tinea corporis during this period, followed by species of the Trichophyton mentagrophytes complex. Moreover, Microsporum audouinii was the main etiological agent of Tinea capitis (TC) with a frequency of 52.5% on average between 2012 and 2016. Other African dermatophytes species such as Trichophyton soudanense and Trichophyton violaceum were also agents of TC with a respective prevalence of 11.6% and 11.5% on average. This study highlights a different dermatophyte distribution in Belgium in comparison with other European countries.
