1. Synergistic antifungal activity of the lipophilic fraction of Hypericum carinatum and fluconazole
ABSTRACT Hypericum species, Hypericaceae, are recognized as a source of therapeutical agents. Purified fractions and isolated compounds have been shown antimicrobial activity. As the indiscriminate use of antifungals and the increase of infections caused by emerging species are leading to the search of new alternative treatments, the aim of this study was to

2. Antifungal activity of topical microemulsion containing a thiophene derivative
Fungal infections have become a major problem of worldwide concern. Yeasts belonging to the Candida genus and the pathogenic fungus Cryptococcus neoformans are responsible for different clinical manifestations, especially in immunocompromised patients. Antifungal therapies are currently based on a few chemotherapeutic agents that have problems related to eff

3. Comparação das técnicas micromorfológicas e moleculares na pesquisa e identificação de Malessezia spp em individuos sadios e com manifestações dermatológicas. / Comparison of the techniches micromorphological and molecular in the research and identification of Malassezia spp. in healthy individuals and with dermatological manifestations.
Espécies de Malassezia fazem parte da microbiota de humanos e de animais. Essas leveduras lipofílicas são microrganismos oportunistas que estão associados com muitas doenças superficiais como: pitiriase versicolor, dermatite seborréica, foliculite, dermatite atópica e algumas infecções sistêmicas. As espécies de Malassezia têm sido identificadas

4. Antagonistic interactions between azoles and amphotericin B with yeasts depend on azole lipophilia for special test conditions in vitro.
The interactions of the azole antifungal agents fluconazole, itraconazole, ketoconazole, or miconazole with amphotericin B (AmB) in their effect on Candida albicans were investigated. These four azoles antagonized the fungistatic activity of AmB at sub-MICs if both substances acted simultaneously. This coincubation test was primarily developed to observe the

5. Reevaluation of the yeast killer phenomenon.
The killer effect of 36 Hansenula, Pichia, Saccharomyces, and Candida species on 26 hyphomycetes isolates, 1 isolate of the achlorophyllous microorganism Prototheca, 4 isolates of the lipophilic yeast Malassezia, 1 isolate of the aerobic actinomycete Nocardia, and 19 isolates of bacteria was studied. The killer phenomenon, which was previously considered to

6. Comparative Enumeration of Lipophilic and Nonlipophilic Cutaneous Diphtheroids and Cocci
Swabbing skin to collect bacteria for enumeration revealed that a single washing or rinsing of the swab in buffer removed between 90 and 95% of the bacteria collected. Further removal of the remaining bacteria from the initial swab by repeated washings of the swab produced plate counts that showed nearly proportional decreases in the numbers and types of bac

7. Description of a New Yeast Species, Malassezia japonica, and Its Detection in Patients with Atopic Dermatitis and Healthy Subjects
Lipophilic yeasts of the genus Malassezia are part of the normal cutaneous microflora and are considered one of the factors that trigger atopic dermatitis (AD). We isolated two strains of Malassezia from a healthy Japanese female. Analysis of the D1/D2 26S ribosomal DNA and internal transcribed spacer region sequences of the isolates suggested that they are

8. Human infections due to Malassezia spp.
The genus Malassezia contains three member species: Malassezia furfur and Malassezia sympodialis, both obligatory lipophilic, skin flora yeasts of humans, and Malassezia pachydermatis, a nonobligatory lipophilic, skin flora yeast of other warm-blooded animals. Several characteristics suggest the basidiomycetous nature of these yeasts, although a perfect stag

9. Molecular Analysis of Malassezia Microflora on the Skin of Atopic Dermatitis Patients and Healthy Subjects
Members of the genus Malassezia, lipophilic yeasts, are considered to be one of the exacerbating factors in atopic dermatitis (AD). We examined variation in cutaneous colonization by Malassezia species in AD patients and compared it with variation in healthy subjects. Samples were collected by applying transparent dressings to the skin lesions of AD patients
