  Candida dubliniensis - Wikipedia, the free encyclopedia
Candida dubliniensis is an organism associated with AIDS patients.
Candida dubliniensis is an opportunistic pathogen that can cause both superficial and invasive infections, (mostly in the immunocompromised).
In a test on C. dubliniensis in HIV+ patients in Maryland, most isolates were highly susceptible to fluconazole, though one was dose-dependent susceptible, (16 µg/mL), meaning a high dose of fluconazole given to the patient would halt the yeast.

Candida dubliniensis is an emerging pathogen capable of causing oropharyngeal, vaginal and bloodstream infections.
dubliniensis is similar to Candida albicans in several phenotypic characteristics, it differs from it with respect to epidemiology, certain virulence factors and the ability to develop resistance to fluconazole rapidly.

 Candida dubliniensis: an emerging opportunistic pathogen.
Candida albicans remains the most important fungal pathogen and is frequently associated with oral candidiasis in HIV-infected individuals.
However, they have unusual carbohydrate assimilation patterns and grow poorly or not at all at 42 degrees C. Using a variety of DNA fingerprinting techniques and karyotype analysis, the genomic organization of C. dubliniensis was shown to be distinctly different from that of C. albicans.
Classification of C. dubliniensis as a separate species was confirmed by phylogenetic analysis, whereby the comparison of ribosomal RNA sequences demonstrated that C. dubliniensis isolates formed a cluster clearly distinct from other Candida species, including C. albicans, to which it is most closely related.

Candida is a member of normal flora of skin, mouth, vagina, and stool.
