Evaluation of API ID 32C and VITEK-2 to identify Candida dubliniensis.
We have compared two diagnostic systems, API-ID32C (bioMerieux) and VITEK-2ID-YST (bioMerieux), in their ability to diagnose 50 clinical isolates of Candida dubliniensis. API identified 48 isolates and VITEK-2 identified 33 of the 50 isolates. Lactic acid assimilation showed highly dispersed results with API, being of special importance, since this test is one of the four that makes it possible to differentiate C. dubliniensis from C. albicans. The detection of one enzyme, Phosphate-4MU, was always positive with VITEK-2 when it should have been negative. Overall, API ID 32C obtained better results than VITEK-2. However, the latter is simpler to use and has a greater database.
