Methods Germ tube test, chlamydospore test, CHROMagar Candida and API20 kit system were applied to separate non-Candida albicans strains from Candida albicans. Then PCR was used to amplify the internal transcribed spacer region of ribosomal DNA from 4 species of common Pathogenic non-Candida albicans (Candida glabrata, Candida parapsilosis, Candida krusei and Candida tropicalis), and the products were digested with the two restriction endonucleases (Msp Ⅰ and Hae Ⅲ) respectively. Results The four isolates consisted of 15 strains of Candida glabrata (7.50%), 7 strains of Candida parapsilosis (3.50%), 5 strains of Candida krusei (2.50%), 2 strains of Candida tropicalis (1.00%).
