Abstract

Introduction: Dermatophytes are fungi that require keratin for growth. These
fungi can cause skin, hair, and nail infections. Dermatophytes are spread by
direct contact from other people (anthropophilic organisms), animals (zoophilic
organisms), and soil (geophilic organisms), as well as indirectly from fomites.
Dermatophyte infections can be readily diagnosed based on the history, physical
examination, and potassium hydroxide (KOH) preparation. Variable clinical
forms require different therapeutic approaches. The aim of this study was to
analysis different clinical types of dermatophytosis and their etiologic agents as well.
Methods: In this epidemiological study, a total of 402 clinically suspected cases
of dermatomycoses ,from three different dermatology clinics in Bandar Abbas
were examined for causative fungi during September 2003 to March 2005.. The
patients were clinically examined by dermatologist. The causative organisms
were identified by potassium hydroxide preparation and cultured in Sabouraud
dextrose agar slants. Macroscopic appearances of colonies, microscopic
examination through slide culture and biochemical tests were used to identify the
fungi. The results were presented using descriptive statistics.
Results: From total 402 suspected cases, 299 were culture positive. The most
frequent clinical form of dermatophytosis, were Tinea cruris (37.5%), tinea
capitis (22.5%), tinea corporis (20.7%). Male patients were infected mainly with
tinea cruris, tinea capitis and tinea pedis, while female patients were infected
mainly with tinea unguium. Nevertheless, the incidence of tinea manuum in
males was the same as those in females. The non-inflammatory 'gray patch'
variety was the most common clinical type. The most frequent isolated agents,
were Trichophyton mentagrophytes (35.8%), T. rubrum (25.1%), and
Epidermophyton fluccosum (22.4%)
Conclusion: Dermatophyte infections are still a major health issue in the region.
To plan strategies for infection control, epidemiological surveys are essential.
This study revealed that the main etiologic fungi were anthropophilic. In order to
diminish dermatophytosis, sanitary conditions should be improved.
