GUTIERREZ, Carolina et al. Sensitivity to Fluconazol and Voriconazol in Candida spp. isolates from the oral mucosa of HIV positive patients . Infect. [online]. 2007, vol.11, n.4, pp.183-189. ISSN 0123-9392.

Abstracts The susceptibilities to Fluconazol (FCZ) and voriconazol (VCZ) susceptibility of Candida spp. isolates, obtained from the oral mucosa of 54 AIDS patients hospitalized in Hospital La María (Medellín, Colombia) were assesed. Additionally, the yeast species were identified to species. Patients were all adults (mean, 40,5 years old, range 23 to 56) and most (77,8%) were males. Candida spp. was isolated from 40 of them (71.1 %) with 6 (11,1%) showing more than one species. The species identified were C. albicans., C. krusei, C. tropicalis, C. parapsilosis and C. glabrata. In vitro agar diffusion susceptibility testing was done according to the CLSI M44P specifications. Most of the Candida species (72.9%) were susceptible to fluconazole with 6,3% susceptible-dose-dependant (SDD) and 20.8% resistant. Voriconazole susceptibility was higher (89,6%) with 8,3% SDD and 2,1% resistant. Resistance was recorded for C. albicans and C. krusei isolates. The results demonstrate the effectiveness of both antifungals with voriconazole performing better. The importance of the in vitro susceptibility tests in HIV/aids patients harboring resistant species was demonstrated and indicated the need to classify all Candida isolate al Candida isolates to the species level.
