To investigate the clinical features of dermatophytes and the resistance of the isolates to several antifungal agents, and to guide the clinical treatment of dermatophytes.

During June 2015 to June 2016, direct fungi microscopy, culture and susceptibility testing from dermatophytes patients at a hospital dermatology clinic were taken.

Among the 110 cases, 49 cases (44.5%) were with skin ringworm tinea, 30 cases (27.3%) with jock itch, 16 cases (14.5%) with tinea, 9 cases (8.2%) with tinea capitis and 6 cases (5.5%) with onychomycosis. The strains isolated from tinea patients were 28 strains (25.5%) of Trichophyton rubrum, 12 (10.1%) of Microsporum canis, 4 strains (3.6%) of Trichophyton mentagrophytes and 5 strains (4.5%) of Epidermophyton floccosum. The common isolated strains from tinea, brothers tinea, tinea capitis, onychomycosis were Trichophyton rubrum with 28 strains (25.5%), 13 strains (11.8%), 6 strains (5.4%), 6 strains (5.5%) and 5 strains (4.5%), respectively. The sensitivity of the isolated strains to clotrimazole was the highest (105 cases, 95.5%), followed by miconazole (93 cases, 84.5%), griseofulvin (51 cases, 46.4%) and fluconazole (104 cases, 94.5%).

Tinea corporis was the most common skin tinea disease (except the tinea), with the incidence rate of men higher than women, the most common clinical isolates was Trichophyton rubrum. 10% KOH tabletting microscopy and fungal culture were effective method for diagnosis of skin tinea disease, and was most sensitive to clonazole.
