Presumptive identification of Candida kefyr on levine formulation of eosin methylene blue agar.

Three hundred thirty-one yeast and yeast-like isolates were cultivated on eosin methylene blue agar. While the sensitivity rate for Candida kefyr isolates producing a metallic green sheen was 81.8%, the high positive predictive value (100%) for yeast isolates with this phenotype belonging to C. kefyr suggests that these isolates can be presumptively identified as C. kefyr.
