Abstract
Some Candida species which were si to each other in phenotypic characteristics were studied by chemotraxonomic and molecular taxonomic comparison including the ubiquinone systems, electrophoretic karyotypes, DNA base composition and DNA relatedness. Candida viswanathii and Candida lodderae showed similar electrophoretic karyotypes and DNA base composition and demonstrated 89 to 90% DNA relatedness, confirming their synonymy.
