目的 研究甲真菌病病甲的形态学特征与致病真菌类型或菌种之间的关系，为临床快速推断致病真菌建立依据。方法 360例门诊甲真菌病患者，观察临床分型和特征，牙钻机取材，镜检和培养确定致病真菌。结果 经培养确定致病真菌感染者 165例，其中皮肤癣菌占 80.0％，酵母菌 13.9％，霉菌 2.4％，混合感染 3.6％。结论 根据甲真菌病病甲的形态学特征，可以大致推断致病菌的种类。 Objective To study the relationship between the morphological features of onychomycosis A and pathogenic fungi or strains so as to establish the basis for rapid inference of pathogenic fungi. Methods A total of 360 outpatients with onychomycosis were enrolled in this study. The clinical classification and characteristics were observed, the dental drill was drawn, and the pathogenic fungi were identified by microscope and culture. Results 165 strains of pathogenic fungi were identified by culture, of which dermatophytes accounted for 80.0%, yeasts 13.9%, molds 2.4% and mixed infections 3.6%. Conclusion According to the morphological features of onychomycosis A, the species of pathogenic bacteria can be roughly inferred.
