Dermatophytoses are considered a public health problem. The objectives of this study were to determine the evolution their prevalence in metropolitan area Porto Alegre, Brazil, and analyze dermatophyte species distribution according body site demographic characteristics patients.This work was retrospective analysis data from patients attending tertiary care hospital during 1996-2011.There 9,048 cases with cultures positive for dermatophytes. Trichophyton rubrum occurred 59.6% cases, followed...
Summary Chromoblastomycosis is a chronic mycosis that affects the skin and subcutaneous tissues caused by several genera of dematiaceous fungi. There not treatment choice. Thus, tools help guide clinical practice are fundamental. In this sense, antifungal activity tests in vitro could be useful. However, trials with chromoblastomycosis agents scarce. The aim study was to evaluate both susceptibility 60 five antifungals combination amphotericin B (AMB) terbinafine ( TRB ). , itraconazole...
Pityriasis versicolor is the most common of diseases caused by Malassezia yeasts. The aim this study to determine prevalence pityriasis and its etiological aspects in metropolitan area Porto Alegre, Brazil. A retrospective cross-sectional with data from patients a reference hospital 1996 2011 was performed. Collected included: date, age, gender, ethnicity, anatomical region lesion direct mycological examination results. Among positive results examination, 5.8% (2,239) were for versicolor....
Summary The burden of histoplasmosis has been poorly documented in most the endemic areas for disease, including Brazil. Also, modern non‐culture‐based diagnostic tests are often non‐available these regions. This was a prospective cohort study HIV ‐infected patients with suspected disseminated disease evaluated different tests. Patients were enrolled three referral medical centres Porto Alegre, Among 78 patients, confirmed eight individuals (10.3%) by means classical (culture/histopathology)...
We report a case of an 80-year-old Brazilian man, farmer, with lesions on the dorsum hand. A direct mycological examination, cultivation and microculture slide observation was performed. The sequencing ITS1-5.8S rDNA-ITS2 region carried out etiological agent confirmed as Exophiala spinifera. in vitro susceptibility this isolate to antifungal agents alone combination evaluated. This is third phaeohyphomycosis caused by spinifera Brazil.
Plants of the genus Pterocaulon (Asteraceae) are popularly used in treatment skin diseases caused by fungi and bacteria. The aim this work was to investigate vitro activity crude methanolic extract obtained from aerial parts alopecuroides (Lam.) against some agents chromoblastomycosis, a chronic fungal infection subcutaneous tissue traumatic inoculation aetiological agent. active all strains tested showing minimum inhibitory concentration between 625 2500 μg ml−1. assessment...
The development of azole antifungals has allowed for the treatment several fungal infections. However, use these compounds is restricted because their hepatotoxicity or they need to be administered together with other drugs in order prevent resistance monotherapy. Benzoxazole derivatives are among most thriving molecular prototypes antifungal agents. 2-(2'-hydroxyphenyl) benzoxazoles versatile molecules that emit fluorescence and have antibacterial, antiviral properties....
The yeasts of the genus Candida infect skin, nails, and mucous membranes gastrointestinal genitourinary tract. aim this study was to determine prevalence dermatomycoses caused by spp., their etiological aspects in metropolitan area Porto Alegre, Brazil. A retrospective with data obtained from tertiary hospital patients, 1996 2011, performed. analyzed parameters were date, age, gender, ethnicity, anatomical region lesions, direct examination results. For all statistical analyses, a = 0.05...
The aim of this study was to develop and characterize antigens for the diagnosis aspergillosis. Nine strains Aspergillus species fumigatus , flavus niger were grown in Sabouraud Smith broth produce exoantigens. tested by immunodiffusion against sera from patients with aspergillosis other systemic mycoses. protein fraction detected SDS–PAGE; Western blot representative bands assessed mass spectrometry coupled a nano Acquity UltraPerformance LC analyzed Mascot search engine. Concurrently, all...
Statins are used as cholesterol-lowering drugs and may also have direct antimicrobial effects.To evaluate synergic interactions between simvastatin both amphotericin B fluconazole, against environmental strains of Cryptococcus neoformans isolated from captive birds' droppings.Experimental study conducted at Federal University Piauí, Parnaíba, in collaboration with Triângulo Mineiro, Uberaba, Brazil.Statin susceptibility tests samples were performed prescribed standards. Interactions...
Introduction Sporothrix schenckii is a thermal dimorphic pathogenic fungus causing subcutaneous mycosis, sporotrichosis. Nitrocoumarin represents fluorogenic substrate class where the microbial nitroreductase activity produces several derivatives, already used in other enzyme assays. The objective of this study was analysis 6-nitrocoumarin (6-NC) as to schenckii. Methods Thirty-five samples S. were cultivated for seven, 14 and 21 days at 35 °C microculture containing or 6-aminocoumarin...
O presente estudo tem como objetivo descrever por meio da literatura o manejo clínico Paracoccidioidomicose pulmonar. utilizou método a revisão integrativa literatura, realizado via Biblioteca Virtual de Saúde (BVS), e uma busca nas bases dados Medline, Pubmed Scielo (Scientific Electronic Library Online) usando os cruzamentos descritores “Paracoccidioidomycosis”, “Diagnosis”. Para avaliação do problema pesquisa sua estratificação foi utilizada estratégia PVO sendo formulada seguinte que...
A 63-year-old man with type 2 diabetes, resident on the north coast, Rio Grande do Sul, Brazil, was referred to dermatology health service at Santa Casa de Porto Alegre due a nodular subcutaneous lesion left ankle (Fig. 1a) in May 2012. He underwent direct and cultural mycological examinations, former, septate hyphae were detected 1b). In latter, material from injury inoculated Mycosel Sabouraud agar chloramphenicol incubated for 15 days 35°C. This showed growth of filamentous fungus initial...
