| This study investigated the prevalence of C. dubliniensis in a Brazilian family with an HIV - infected child. A total of 42 oral isolates were obtained from eight family members. The identification of C. dubliniensis was performed by polymerase chain reactions (PCR) using primers against a specific sequence of the C. dubliniensis cytochrome b gene. Only the HIV-infected child and his grandmother were colonized by C. dubliniensis. In this study C. dubliniensis isolated from the HIV-infected child exhibited high susceptibility for azoles tested with MICs of 0.125 and 0.5 µg/mL for voriconazole and fluconazole, respectively. Accumulation of [³H] fluconazole in C. dubliniensis isolated from the HIV-infected child was slightly reduced in comparison to the... |

| Declining incidence of oropharyngeal candidosis and opportunistic infections over recent years can be attributed to the use of highly active anti-retroviral therapy (HAART). Infection with C. albicans generally involves adherence and colonization of superficial tissues. During this process, budding yeasts are able to transform to hyphae and penetrate into the deep tissue. Using the biocell tracer system, C. albicans hyphal growth was dynamically observed at the cellular level. Ritonavir was effective in the inhibition of hyphal growth with growth rate of 0.8 mum/min. This study showed the in vitro effect of HIV anti-retroviral drug on the growth rate of the C. albicans hyphae. |
