RFLP patterns of PCR-amplified rDNA obtained from one clinical isolate and the type strains of C. inconspicua, C. norvegensis, and C. krusei. Lane M, molecular size standard; lane 1, isolate N-22838; lane 2, C. inconspicua ATCC 16783; lane 3, C. norvegensis ATCC 22977; lane 4, C. krusei ATCC 6258. MspI, RsaI, ScrFI, and HaeIII were the restriction enzymes used to digest the PCR products.
