Molecular Determination of Dermato phyte Fungi Using Arbitrarily Prime d Polymerase Chain Reaction / 中华皮肤科杂志

ABSTRACT

Objective To study the significance of AP-PCR i n identification and subtyping of der-matophytes.Methods Using a pair of random primers,OPAA11(5' -ACCCGACCTG -3' ),and OPD18(5' -GAGAGCCAAC -3' )the DNAs of 64isolates of dermatophytes(9species of 3genera),Sporothrix schenckii and Candida albicans were amplified by AP-PCR and analyse d by electrophoresis.Results Distinct DNA band patterns were observed in diffe rent dermatophyte species.Common major DNA bands were observed in Trichophyton rubrum isolated from different areas with s train difference.Conclusion Using OPAA11and OPD18as primers,AP-PCR may be applied in the identification and subtypi ng of dermatophytes.
