RESUMEN
Objective To analyze fungal isolates from patients with superficial fungal infections during 1960-2006.Methods Fungal strains isolated from patients with superficial (mucocutaneous and cutaneous)fungal infections and identified in the Medical Mycology Clinical Laboratory,Department of Dermatology and Venereology,Union Hospital,from 1960 to 2006 (data from September 1991 to July 1992 were unavailable),were subjected to a classification and statistical analysis.Clinical samples for mycological examination were taken from outpatients or inpatients of different departments in hospitals of Hubei province and surrounding areas.Morphological,physiological and biochemical methods were applied for species identification.Results A total of 11 989 Candida strains were isolated,which belonged to 23 species and 16 genera.They fell into 3 groups,i.e.,dermatophytes,Candida and yeasts (including Malassezia),and non-dermatophyte moulds.Since 287 strains of moulds were suspected to be contaminating fungi,11 702 residual isolates were analyzed.Of the analyzed isolates,Candida species (5642/11 702,48.2％ )and dermatophytes (5279/11 702,45.1％ )predominated,followed by yeasts (449/11 702,3.8％) and Malassezia species (332/11 702,2.8％).The most frequently isolated species was Trichophyton rubrum (3865/11 702,33.0％),Candida albicans (3110/11 702,26.6％ ) and non-albicans Candida species (2532/11 702,21.6％ ).Dermatophyte strains were mostly isolated from lesions of smooth skin with an exception of palmoplantar and interdigit regions (1787/5279,37.7％).The most common dermatophyte species was Trichophyton rubrum,followed by Trichophyton violanceum.Candida was mainly isolated from mucous membrane lesions (4099/5642,72.7％),with Candida albicans being the predominant species.Conclusions Candida species and dermatophytes predominate in patients with superficial fungal infections during 1960-2006,with Trichophyton rubrum being the most common species.
