Candida spp was isolated from 59 (68.60%) out of eighty six samples of oral mucosa of AIDS patients. The identification, based or the production of a germ tube and chlamydospores, and on the assimilation and fermentation of carbohydrates, revealed 52 strains (88.13%) of C. albicans, 4 (6.77%) of C. tropicalis and 3 (5.08%) of C. krusei. The susceptibility of these strains to amphotericin B, flucytosine, itraconazole, fluconazole and ketoconazole was determined using the agar dilution method. Comparing the minimum inhibitory concentration values found in the susceptibility test with the serum levels achieved by these drugs, only 8.47% and 5.08% of the yeasts strains proved to be resistant to amphotericin B and flucitosyne, respectively. A high frequency of...

Ethanolic extracts from leaves of Hyptis ovalifolia, H. suaveolens, H. saxatilis, Hyptidendrum canum, Eugenia uniflora, E. dysenterica, Caryocar brasiliensis and Lafoensia pacari were investigated for their antifungal activity against dermatophytes. The most effective plants were H. ovalifolia and E. uniflora, while Trichophyton rubrum was the most sensitive among the four dermatophytes species evaluated. This study has demonstrated antifungal properties of Brazilian Cerrado plant extracts in "in vitro" assays.

Susceptibility testing of Candida albicans isolated from oropharyngeal mucosa of HIV+ patients to fluconazole, amphotericin B and Caspofungin: killing kinetics of caspofungin and amphotericin B against fluconazole resistant and susceptible isolates

A clear understanding of the pharmacodynamic properties of antifungal agents is important for the adequate treatment of fungal infections like candidiasis. For certain antifungal agents, the determination of Minimal Fungicidal Concentration (MFC) and time kill curve could be clinically more relevant than the determination of the Minimal Inhibitory Concentration (MIC). In this study, MIC and MFC to fluconazole, amphotericin B and caspofungin against C. albicans isolates and the killing patterns obtained with caspofungin and amphotericin B against susceptible and resistant strains to fluconazole were determined. The results of MICs showed that all C. albicans isolates were highly susceptible to amphotericin B, but two isolates were fluconazole resistant. The...
