Abstract:

Objective To investigate the role of fluorescent dye Calcofluor White(CFW) in the diagnosis of fungal infection,and to compare with KOH microscopic examination and fungal culturing,so as to find an effective method for detecting fungi. Methods A total of 150 clinically suspected patients with fungal infection were enrolled,and the samples were detected by CFW,KOH microscopic examination and fungal culturing. Results The positive rate of CFW was 85.8%,the positive rate of KOH microscopic examination and fungal culturing were 76.1% and 71.0%,respectively. There was statistical significance between CFW and KOH microscopic examination(χ2=14.45,P<0.05). Conclusions CFW could improve positive rate,and it is an effective method for detecting fungi.

Key words: Fluorescent dye Calcofluor White, KOH, Fungal culturing
