26S rDNA PCR-RFLP pattern in the six Malassezia standard strains. 26S rDNA PCR products were digested with two restriction enzymes. (A) Hha1; all the six standard strains showed different RFLP patterns. (B) BstF51; M. globosa and M. obtusa showed the same RFLP patterns. The other four strains all showed different patterns. Lane M: marker, lane 1: M. furfur, lane 2: M. globosa, lane 3: M. restricta, lane 4: M. obtusa, lane 5: M. sympodialis, lane 6: M. slooffiae.
