Analysis of Pathogenic Fungi Strains in 305 Cases of Onychomycosis in Hunan Chenzhou

Objective To survey the clinical classification of onychomycosis and the components of pathogenic fungi strains in Chenzhou of HuNan province.Methods Direct microscopic examination,fungi culture,identification and clinical analysis on 305 samples from patients with clinical suspected onychomycosis which located in different area of Chenzhou were performed.Results Of all the 305 cases of onychomycosis,thepositive fungal cultures were 257,the positive rate was 84.26%,267 fungi were isolated,including dermatophytes were 143 strains(53.56%),such as pro-human and pro-animal small spores were 35 strains(24.48%),the Yeast were 106 strains(39.70%),molds were 18 stains(6.74%).DLSO were the most frequently clinical patterns in the 305 cases.Conclusion DLSO is the major type of onychomycosis.The major pathogenic fungi of onychomycosis is dermatophytes,followed by yeasts and saprophytic molds.The high isolation rate of pro-human and pro-animal small spores should be pay attention to.
