805例甲真菌病真菌培养结果分析

Analysis of pathogenic fungi of 805 cases with onychomycosis

目的了解近年来我院甲真菌病病原菌的种类和构成分布情况，并研究其流行病学特点。方法收集2008年6月-2012年11月间我院皮肤科实验室甲真菌病患者病甲真菌学培养阳性的病例并进行分析。结果共收集到805例病甲真菌培养阳性的甲真菌病病例。酵母菌407株，占50．55％，皮肤癣菌385株，占47．95％，霉菌13株，占1．61％。不同年龄段的甲真菌病患者的菌属分布存在差异。结论我院近年来甲真菌病病原菌最常见为酵母菌，其次为皮肤癣菌和霉菌。年龄是影响菌属分布的重要因素。

Objective To investigate the types and composition of pathogens of onychomycosis in the Guangzhou area in recent years. Methods The mycology culture-positive patients of onychomycosis were collected and analyzed in our hospital dermatology la- boratory were analyzed from June 2008 to Octobor 2012. Results In the 805 cases of mycology culture-positive pathogenic fungus, the most frequently fungus were yeast （50.55%） , followed by the dermatophytes （47.95%）. Mold is ranked third, accounting for （ 1.61% ）. The distibution of different fungal species have a difference at different ages. Conclusion The most frequent fungus spe- cies of onychomycosis patients in our hospital is yeast, followed by dermatophytes and molds. Age is an important factor affecting the fungal species distribution.
