Aetiological agents of tinea capitis in Tehran (Iran)

A total of 1568 patients with suspected tinea capitis were examined for causative fungal agents between 1994 and 2001. Laboratory examination confirmed tinea capitis in 209 patients. Males were affected more frequently (67.5%) than females (32.5%) and in both sexes, those who were 3–11 years old, were more infected. Trichophyton violaceum was the most common aetiological agent (37.3%) followed by Trichophyton schoenleinii (21.5%), Microsporum canis (18.6%), Trichophyton verrocosum (14.8%), Trichophyton tonsurans (5.3%), Trichophyton rubrum (1%), Microsporum gypseum (1%) and Trichophyton mentagrophytes (0.5%). A higher incidence of the disease was found to be correlated with larger family and class size. The findings are discussed in relation to different socioeconomic and hygienic backgrounds of the children.
