title: Skin Infection due to Trichophyton tonsurans Still Occurs in People in Korea but not as Outbreaks.
abstract: Since 1995, Trichophyton tonsurans has been one of the causative agents of dermatophytosis in Korea. Herein we evaluate 77 patients infected with T. tonsurans who visited an outpatient clinic between 2004 and 2014. Infections due to T. tonsurans were diagnosed by mycological examination, which included direct microscopic examination using 15% KOH and culture in potato dextrose agar complemented with 0.5% chloramphenicol. The annual prevalence of infection due to T. tonsurans was the highest in 2014 (15 cases) but remained constant in non-gladiators between 2004 and 2014. The ratio of male to female patients was 1:0.3. The spring season presented the highest incidence compared with other seasons, with 27 cases. The incidence of infections due to T. tonsurans among gladiators was highest in spring compared with the other seasons whereas the incidence in non-gladiators was the highest in the winter. The body site most commonly affected was the face. Tinea corporis was the most common subtype of dermatophytosis caused by T. tonsurans. Herein, we demonstrate that the prevalence of infection with T. tonsurans remain constant throughout the study period in Korea.
