摘要

Objective:This study aimed to analyze the fungal species of pathogens isolated from patients with superficial mucocutaneous mycosis from May 2007 to December 2018.Methods:A retrospective analysis was carried out to determine the pathogenic fungi isolated from patients with superficial fungal infections in the Medical Mycology Clinical Laboratory,Department of Dermatology and Venereology,Union Hospital,from May 2007 to December 2018.Results:A total of 7639 strains were obtained,belonging to 21 genera and 36 species.They mainly consisted of Candida(3707/7639,48.53％)and dermatophytes(3594/7639,47.05％).The specimens were skin scales,nail shavings,secretions on the nail grooves,broken or diseased hair and dandruff,secretions or pseudomembrane of the external genitalia,and the oral mucosa.A total of 7300 patients were enrolled in this study,including 3301 males and 3999 females aged 2 months to 92 years old with a median age of 46.04 years old except for 633 patients whose ages were unknown.Two strains of different species were isolated from each of 339 patients at different body sites.The most frequent species were Trichophyton rubrum complex(2906/7639,38.04％),Candida albicans(2619/7639,34.28％),and unclassified Candida spp.Dermatophytes were mostly isolated from glabrous skin(2138/3594,59.49％),with T rubrum complex being the predominant species.Candida strains were most commonly isolated from mucosal sites(1979/3707,53.39％),and C.albicans was the most prevalent causative agent.Conclusion:The main distribution of pathogenic fungal species isolated from patients with superficial mycosis from 2007 to 2018 in Wuhan,Hubei province and the surrounding areas was that Candida slightly outnumbered dermatophytes.Among all of the isolated strains,T.rubrum complex was the most.abundant.
