ABSTRACT
To establish a simple, sensitive and effective technique for the identification of six common dermatophytes, polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP) targeting Topoisomerase Ⅱ gene were used. The DNA of 6 common dermatophytes was amplified by primer dPsD1 and then primers dPsD2. The products generated by dPsD2were digested with restriction enzyme Hinc Ⅱ and Hinf Ⅰ separately. A DNA fragment of about 3390 bp was amplified by using primer dPsD1 from the genomic DNA of each dermatophyte species. The product of dPsD2 was 2380 bp and the restriction profiles of Hinc Ⅱ and Hinf Ⅰ were between 58- 1670 bp. By using PCR-RFLP, all of the 6 dermatophytoses were diagnosed to species level and no obvious difference identification between Hinc Ⅱ and Hinf Ⅰ. It is concluded that the PCR-RFLP identification of dermatophytes by Hinc Ⅱ or Hinf Ⅰ is efficient and rapid in clinical practice.
