Identificación rápida de Candida dubliniensis mediante la prueba Bichro-Dubli®

Abstract

Because of its considerable epidemiological relevance, accurate identification of Candida dubliniensis should be routinely performed in clinical microbiology laboratories. In an attempt to facilitate this task, the usefulness of the Bichro-Dubli test (Fumouze Diagnostics, Levallois-Perret, France) was assessed. Seventy-five collection strains (55 C. dubliniensis and 20 C. albicans) and 135 clinical yeast isolates that grew as green colonies in CHROMagar Candida were studied. Bichro-Dubli was positive in 54 of 55 C. dubliniensis strains (sensitivity 98.2%) and negative in the 20 C. albicans strains (specificity 100%). The test identified 4 C. dubliniensis isolates among the 135 isolates cultured from clinical specimens. The Bichro-Dubli test is easy to perform and allows rapid identification of C. dubliniensis.
