The incidence of Candida dubliniensis in oropharyngeal swabs of 132 human immunodeficiency virus (HIV)-positive and 89 HIV-negative patients was determined. The samples were plated onto CHROMagar Candida medium and 82 strains, presumptively identified as C. albicans or C. dubliniensis, were further investigated (temperature test, chlamydoconidia production, specific primer PCR). In addition, 487 collection strains (isolated from clinical samples and previously identified as C. albicans on the basis of a positive germ tube test) were screened in order to identify C. dubliniensis isolates. Two C. dubliniensis strains were isolated from two HIV-positive patients without oral candidiasis. Candida dubliniensis was not isolated from 89 HIV-negative patients nor was it identified among the collection strains.
