Title: Molecular taxonomy of dermatophytes and related fungi by chitin synthase 1 (CHS1) gene sequences. Author: Hirai A, Kano R, Nakamura Y, Watanabe S, Hasegawa A. Journal: Antonie Van Leeuwenhoek; 2003; 83(1):11-20. PubMed ID: 12755475. Abstract: In the present study, the nucleotide sequences of the CHS1 gene from dermatophytes and related fungi in the genera Chrysosporium, Epidermophyton, Microsporum and Trichophyton were investigated using molecular methods. About 440-bp genomic DNA fragments of the CHS1 gene from 21 species were amplified by polymerase chain reaction (PCR) and sequenced. The CHS1 nucleotide sequences of these fungi showed more than 83% similarity. The molecular taxonomy of the CHS1 gene sequences revealed that Microsporum was genetically distinct from Chrysosporium and Trichophyton, as classified by morphological characteristics.[Abstract] [Full Text] [Related] [New Search]
