Carbohydrate assimilation profiles of Brazilian Candida dubliniensis isolates based on ID 32C system

Abstract

Dezenove culturas de C. dubliniensis isoladas no Brasil, previamente identificadas através de métodos genotípicos, foram avaliadas pelo kit comercial ID 32C (bioMerieux). Treze culturas foram identificadas como C. dubliniensis, mas as demais (seis) evidenciaram perfil duvidoso, embora o software do sistema sugerisse 83,6% de chances das mesmas pertencerem à espécie C. dubliniensis. A literatura tem registrado grande variabilidade fenotípica com esta espécie e, por isto, as identificações obtidas com este sistema deverão ser consideradas como presuntivas.

The purpose of the present study was to evaluate the identification of 19 Brazilian C. dubliniensis based on the biochemical profile exhibited when tested by the commercial identification kit ID 32C (bioMerieux). Thirteen of the isolates were rigorously identified as C. dubliniensis and the remaining isolates (six) were considered as having a doubtful profile but the software also suggested that there was 83.6% of chances for them to be C. dubliniensis. As well as pointed by the literature the identification obtained by phenotypic tests should be considered presumptive for C. dubliniensis due to variability of this new species.
