Analysis of pathogenic fungal strains in 400 patients of onychomycosis

Objective:To determine the pathogenic fungal strains isolated from onychomycosis in Shanghai.Methods:Fungal culture was performed on 400 patients of onychomycosis with positive results by direct microscopic examination.Results:A total of 233 strains of fungi was isolated,of which 120 strains were dermatophytes(Trichophyton rubrum in 104 isolates,Trichophyton mentagrophytes in 10,Microsporum canis in 3and Epidermophyton floccosum in 3),68 were Saccharomycetes,11 were non-dermatophytes(Aspergillus 6and Mould 5) and the rest were filamentous fungi.Conclusion:In Shanghai,the dominated pathogenic fungus of onyehomycosis is Trichophyton rubrum,and the non-Candida albicans accounts for a proportion of the yeast.
