1. Evaluation of melanin production by Sporothrix luriei
There is a paucity of studies on the cell biology of Sporothrix luriei, the less common of the pathogenic Sporothrix species worldwide. The production of DHN-melanin, eumelanin, and pyomelanin were evaluated on the mycelial and yeast forms of the S. luriei ATCC 18616 strain. The mycelial form of this species produced only pyomelanin, which protected the fung

2. Screening of thermotolerant and thermophilic fungi aiming β-xylosidase and arabinanase production
Plant cell wall is mainly composed by cellulose, hemicellulose and lignin. The heterogeneous structure and composition of the hemicellulose are key impediments to its depolymerization and subsequent use in fermentation processes. Thus, this study aimed to perform a screening of thermophilic and thermotolerant filamentous fungi collected from different region

3. Growth inhibition and morphological alterations of Trichophyton rubrum induced by essential oil from Cymbopogon winterianus Jowitt ex Bor
Trichophyton rubrum is one of the most common fungi causer of dermatophytosis, mycosis that affect humans and animals around the world. Researches aiming new products with antifungal activity become necessary to overcome difficulties on treatment of these infections. Accordingly, this study aimed to investigate the antifungal activity of essential oil from C

4. Development of experimental sporothichosis in a murine model with yeast and mycelial froms of Sporothrix schenckii / Avaliação do desenvolvimento da esporotricose experimental em camundongos com as formas leveduriforme e filamentosa do Sporothrix schenckii
A esporotricose é uma micose subcutânea causada pelo fungo dimórfico Sporothrix schenckii que acomete o homem e uma grande variedade de animais. Este trabalho teve como objetivos verificar possíveis diferenças de virulência entre inóculos das formas leveduriforme (Y) e filamentosa (M), comparar as reações induzidas pelos dois inóculos em diferentes

5. Paracoccidioidomicose experimental : infecção e doença em animais infectados por um isolado atipico da cepa Pb18 / Experimental Paracoccidioidomycoses infection and disease in animals infected by an atypical isolated of Pb18 strain
P. brasiliensis is a dimorphic fungus that grows in mycelial phase at room temperature and in yeast form at 35-37°C. Recently, in the Immunopathology Laboratory of the Department of Microbiology and Immunology (Biology Institute/Unicamp), it was observed that a sample of the virulent strain Pb18 grew in a different way from other ones. Preliminary analysis

6. Epidemiologia e controle da antracnose em Capsicum spp. e identificação de Colletotrichum spp. associados às solanáceas cultivadas
Although pepper and sweet-pepper anthracnose may be caused by several Colletotrichum species, most domestic (Brazilian) reports identify Colletotrichum gloeosporioides as the main causal agent, with rare records of other species. Twenty-two Colletotrichum isolates were studied as to their mycelial growth, colony coloration and conidial morphology and morphom

7. Enzymes in Glycolysis and the Citric Acid Cycle in the Yeast and Mycelial Forms of Paracoccidioides brasiliensis
Kanetsuna, Fuminori (Instituto Venezolano de Investigaciones Cientificas, Caracas, Venezuela), and Luis M. Carbonell. Enzymes in glycolysis and the citric acid cycle in the yeast and mycelial forms of Paracoccidioides brasiliensis. J. Bacteriol. 92:1315–1320. 1966.—Enzymatic activities in glycolysis, the hexose monophosphate shunt, and the citric acid cy

8. Different levels of DNA methylation in yeast and mycelial forms of Candida albicans.
Isotope dilution gas chromatography-mass spectrometry analysis of genomic DNAs isolated from three Candida albicans isolates showed significant differences in the amounts of 5-methyldeoxycytidine (m5Cyt) in DNA from yeast-form and from mycelial-form cells; the moles percent m5Cyt were 0.11, 0.11, and 0.097 for yeast-form DNA and 0.045, 0.053, and 0.047 for m

9. In Vitro Antifungal Activity of Micafungin (FK463) against Dimorphic Fungi: Comparison of Yeast-Like and Mycelial Forms
The characteristics of in vitro micafungin (FK463) antifungal activity against six species of dimorphic fungi were investigated in accordance with the NCCLS M27-A microdilution methods. MICs of micafungin, amphotericin B, itraconazole, and fluconazole for Histoplasma capsulatum var. capsulatum, Blastomyces dermatitidis, Paracoccidioides brasiliensis, Penicil

10. Glucose metabolism and dimorphism in Mucor.
Mucor racemosus fermented glucose to ethanol, carbon dioxide, and glycerol. When this fungus was grown anaerobically in either the yeast or mycelial form, the catabolism of glucose was very similar. Yeast cells shifted to aerobic conditions maintained a high flux of glucose carbon through the glycolytic and pentose phosphate pathways. Mycelial cells grown ae

11. FLUORESCENT-ANTIBODY STUDIES OF THE MYCELIAL FORM OF HISTOPLASMA CAPSULATUM AND MORPHOLOGICALLY SIMILAR FUNGI
Kaufman, Leo (Communicable Disease Center, Atlanta, Ga.), and Brenda Brandt. Fluorescent-antibody studies of the mycelial form of Histoplasma capsulatum and morphologically similar fungi. J. Bacteriol. 87:120–126. 1964.—Fluorescent-antibody reagents were developed to differentiate the mycelial form of the pathogen, Histoplasma capsulatum, from several mo

12. Estradiol-binding proteins from mycelial and yeast-form cultures of Paracoccidioides brasiliensis.
Paracoccidioides brasiliensis, the etiologic agent of paracoccidioidomycosis, causes disease much more frequently in men than it does in women, suggesting that the hormonal milieu of the host might influence P. brasiliensis pathogenicity. We recently demonstrated that cytosol from yeast cultures of P. brasiliensis contains a high-affinity, low-capacity, trit
