1. Virulence factors of Candida species from the oral mucosa and prostheses of elderly people from a riverside community in the Amazon state, Brazil
Resumo Introdução A Candida albicans é a levedura que mais acomete a cavidade oral, podendo causar infecção. Porém diversos fatores podem estar associados ao aparecimento da candidíase, que podem estar relacionados com a higiene e saúde dos indivíduos, mas também com a patogenicidade destes microrganismos. Objetivo Avaliar os fatores de virulênc

2. Pathogenic characteristics of yeasts isolated from vaginal secretion preserved under mineral oil
In order to evaluate the pathogenicity of yeasts isolated from vaginal secretion of pregnant and non-pregnant women - stored in mineral oil at the URM Mycology Collection, Department of Mycology, Federal University of Pernambuco - 30 samples belonging to the genera Candida, Rhodotorula, Trichosporon, and Kloeckera, were studied regarding their pathogenic cha

3. Otimização do manejo da pinta preta causada por Guignardia citricarpa Kiely na produção ecológica de tangerinas cv. Montenegrina sob a ótica da pesquisa participativa / Optimization of management techniques of black spot (Guignardia citricarpa Kiely.) in ecological orchards of tangerine trees cv. montenegrinafrom the perspective of participatory research
In the state of Rio Grande do Sul many citric species are grown, the town of Montenegro, in Vale do Caí/RS stands out among the most important producers. For the production of fruits for in natura consumption most of the local farmers adopt technological packages that consist in the use of chemical inputs and in environmetal simplification. However, experim

4. Morfotipagem, caracterizaÃÃo fisiolÃgica de leveduras isoladas de secreÃÃo vaginal e sensibilidade a prÃpolis e lectinas
The yeasts, especially the candidoses, are assuming a role of great importance in the human pathology. The female genital tract may be affected by infectious and inflammatory processes, which are diagnosed by examination of vaginal secretion. Several species of yeasts have been isolated from the vulva and vagina in normal cases and vulvovaginitis. Aiming to

5. Onychomycosis caused by filamentous fungi non-dermatophytes / Onicomicoses causadas por fungos filamentosos não dermatófitos
INTRODUCTION: Onychomycosis, a nail fungus infection is the most frequent nail disease, constituting about half of all nail disorder. It can be caused by dermatophytes, yeasts and non- dermatophytes filamentous fungi. OBJECTIVE: Characterize the onychomycosis caused by filamentous fungi non- dermatophytes. (1) Verify after a clinical suspicion of onychomycos

6. Análise comparativa das variações morfológicas entre dois diferentes isolados (Pb01 e Pb18) do fungo Paracoccidioides brasiliensis e da sua interação com o sistema imune do hospedeiro
The dimorphic fungus Paracoccididoides brasiliensis is the etiologic agent of systemic mycosis paracoccidioidomycosis, it is restrict to Latin American. It is frequently diagnosed in Brazil, Colombia and Venezuela. The evolution of this disease depends directly on the interaction between P.brasiliensis and host. Aspects of funguss virulence and the immune ty

7. Caracterização de leveduras isoladas de dialisato e morcegos urbanos
As leveduras são organismos eucariotos, unicelulares, presentes nos mais diversos ambientes. Em pessoas saudáveis, as leveduras vivem como comensais, mas, na presença de certos fatores de risco esses microrganismos podem levar ao desenvolvimento de infecções localizadas ou sistêmicas. Em vista do exposto, o principal objetivo desse trabalho foi avaliar

8. Altered expression of surface protein WI-1 in genetically related strains of Blastomyces dermatitidis that differ in virulence regulates recognition of yeasts by human macrophages.
The molecular basis for pathogenicity and virulence of the dimorphic fungus Blastomyces dermatitidis remains unknown. WI-1 is a major cell wall protein of B. dermatitidis yeasts and is a recognition target of both humoral and cell-mediated immunity. As an initial study to determine if WI-1 might be linked to virulence of B. dermatitidis, we quantified WI-1 e

9. In vitro susceptibility of fungi to killing by neutrophil granulocytes discriminates between primary pathogenicity and opportunism.
Pathogenic fungi, according to their propensity to cause infection of apparently normal individuals, can be grouped into either primary pathogens (e.g., Coccidioides, Histoplasma, Paracoccidioides, Blastomyces, and Sporothrix) or opportunists (e.g., Candida, Mucoraceae, Aspergillus spp., Petriellidium, and Trichosporon). There is, however, no unifying concep

10. Altered expression of surface alpha-1,3-glucan in genetically related strains of Blastomyces dermatitidis that differ in virulence.
Recent studies of the dimorphic fungal pathogens Histoplasma capsulatum and Paracoccidioides brasiliensis have suggested a role in virulence for the cell surface carbohydrate alpha-(1,3)-glucan. To investigate a possible basis for alpha-(1,3)-glucan in the pathogenicity and virulence of the dimorphic fungus Blastomyces dermatitidis, we examined three genetic

11. Signalling in the Yeasts: An Informational Cascade with Links to the Filamentous Fungi
All cells, from bacteria and yeasts to mammalian cells, respond to cues from their environment. A variety of mechanisms exist for the transduction of these external signals to the interior of the cell, resulting in altered patterns of protein activity. Eukaryotic cells commonly transduce external cues via a conserved module composed of three protein kinases,

12. Biofilm formation by Candida species on the surface of catheter materials in vitro.
A model system for studying Candida biofilms growing on the surface of small discs of catheter material is described. Biofilm formation was determined quantitatively by a colorimetric assay involving reduction of a tetrazolium salt or by [3H]leucine incorporation; both methods gave excellent correlation with biofilm dry weight (r = 0.997 and 0.945, respectiv
