Abstract
Our study included 2384 students from five villages around Eski¸ sehir, Turkey. We asked every student for their
personal identification and also for their sanitation in order to get an idea about dermatophytosis. Samples taken
from suspicious lesion were collected and inoculated onto Sabouraud dextrose agar slants. For identification of
fungi which were grown, macroscopic appearance of colonies, microscopic examination and biochemical tests
were used. We found suspicious lesions in 245 (10.3%) and diagnosed dermatophytosis in 86 (3.6%) of the
students. The dermatophyte species were Trichophyton rubrum 37 (43%) at first, Trichophyton mentagrophytes
17 (19.8%), Microsporum canis 11 (12.8%), Microsporum gypseum 8(9.3%), Epidermophyton floccosum 6 (7%),
Trichophyton verrucosum 6 (7%) and Trichophyton violaceum 1 (1.1%). Tinea pedis (59.3%) was the most frequent
clinic form of dermatophytosis, followed by tinea corporis (22.1%), tinea capitis (9.3%), tinea manum (7.0%) and
tinea unguium (2.3%). Older age, male gender, poor hygiene, living in dormitory, low level mother education,
history of dermatophytosis within family and sanitary conditions were computed as independently variables as-
sociated with dermatophytosis infection. For prevention and control of dermatophyte infection in children living
rural areas, field studies should be done and sanitary conditions should be improved.

Introduction
The term dermatophytosis is used to describe infec-
tions of the skin, hair and nails due to a group of
related filamentous fungi, dermatophyte [1]. There
are three genera of dermatophytes, Trichophyton, Mi-
crosporum and Epidermophyton. Members of all three
groups can cause human infection but their different
natural reservoirs have important epidemiological im-
plications in relation to the acquisition, site and spread
of human infections [2]. Dermatophyte infections of
humans and animals are recognized as a major health
problem in many parts of the world. The distribution of
dermatophytes and etiological agents varies with geo-
graphic location; some species are widely distributed
whereas others are geographically restricted. The reas-
ons for this increase in the prevalence of skin mycoses
possibly may be found in the public’s socio-economic
status, poor hygiene and sanitary conditions [3]. The
aim of this study was to estimate the prevalence of
dermatophyte infection in children living in rural areas
of Turkey, as well as to determine risk factors for the
infection.
Materials and methods
This is a cross-sectional study carried out in the rural
region of Eskisehir, in central Turkey. The district con-
sists of 81 villages and five towns in which a total of
60,497 residents have been living; of whom 2501 are
students in high schools. Overall 2384 (95.3%) stu-
dents (945 (39.6%) female and 1439 (60.4%) male;
age range 11–19 years) were included in the study.
This survey was using a two-step approach. In
stage one, the screening questionnaire consisting of
questions soliciting information concerning the stu-
dents sociodemographic back-ground and the hygiene
