173例浅部真菌病致病性真菌菌种分析

Analysis of pathogenic fungi strains in 173 cases of superficial mycosis

目的探讨皮肤浅部真菌病致病真菌菌种的构成。方法对173例真菌涂片阳性的浅部真菌病患者,取标本进行分离培养及菌种鉴定。结果共分离培养出致病菌株9种,其中红色毛癣菌71株(41.04%);须癣毛癣菌32株(18.50%);白色念珠菌25株(14.45%);其他酵母样菌9株(5.20%);犬小孢子菌22株(12.72%);石膏样小孢子菌4株(2.31%);曲霉4株(2.31%);链格孢菌2株(1.16%);絮状表皮癣菌1株(0.58%);混合感染3例(1.73%)。结论浅部真菌病的致病菌仍以皮肤癣菌为主,但其它种类真菌感染有明显上升趋势。

Objective To study components of pathogenic fungi strains in 173 cases of superficial mycosis. Methods The clinical specimens from 173 patients with superficial mycosis, which presented positive results of the direct microscopic examination, were examined with the culture and identification of isolates of causative fungi. Results Nine kinds of pathogenic fungi strains were isolated, including Trichophyton rubrum 71 strains （41.04%）, Trichophyton mentagrophytes 32 strains （ 18.50% ）, Candida Albicans 25 strains（ 14.45% ）, other yeast-like bacterium 9 strains （5.20%）, Microsporum canis 22 strains （ 12.72% ）, Mierosporum gypseum 4 strains （2.31%）, Aspergillus 4 strains （2.31%）, Alternaria ahernata 2 strains （ 1.16% ）, Epidermophyton floccosum 1 strains （0.58%）, and 3 mixed fungal infection （ 1.73% ）. Conclusion The predominant pathogenic fungi of superficial mycosis is dermatophytes. Recently other fungal strains infection have grown significantly.
