Abstract
The sensitivities of Sabouraud dextrose agar and modified Pagano-Levin agar for the primary isolation of yeasts and the recovery of multiple yeast species from single clinical samples were compared by using oral-rinse samples. Although there was a highly significant positive correlation between the numbers of yeasts recovered from both media, modified Pagano-Levin agar was far superior in detecting multiple yeast species in a single sample. Of 150 oral samples containing yeasts, 23 (15.3%) contained more than one yeast species. The most frequent combination of different yeasts was Candida albicans and Torulopsis glabrata.
