Yeast microbiota of free-ranging amphibians and reptiles from Caatinga biome in...
Castelo-Branco,Débora de Souza Collares Maia; Graça-Filho,Renan Vasconcelos da; Oliveira,Jonathas Sales de; Rocha,Maria Gleiciane daABSTRACT: Studies on the fungal microbiota of reptiles and amphibians are necessary to better understand of host-microbe interactions and the establishment of fungal disease in these animals. However, these studies are limited. The present researchidentified yeasts from free-ranging reptiles and amphibians from the Caatinga biome andevaluated the virulence factors production, the antifungal susceptibility in pl...
Terpinen-4-ol, tyrosol, and β-lapachone as potential antifungals against dimorp...
Brilhante,Raimunda Sâmia Nogueira; Caetano,Érica Pacheco; Lima,Rita Amanda Chaves de; Marques,Francisca Jakelyne de FariasAbstract This study aimed to evaluate the in vitro antifungal activity of terpinen-4-ol, tyrosol, and β-lapachone against strains of Coccidioides posadasii in filamentous phase (n = 22) and Histoplasma capsulatum in both filamentous (n = 40) and yeast phases (n = 13), using the broth dilution methods as described by the Clinical and Laboratory Standards Institute, to determine the minimum inhibitory concentrati...
Antiretroviral drugs saquinavir and ritonavir reduce inhibitory concentration v...
Brilhante,Raimunda Sâmia Nogueira; Caetano,Érica Pacheco; Riello,Giovanna Barbosa; Guedes,Glaucia Morgana de MeloAbstract Recent studies have shown that some drugs that are not routinely used to treat fungal infections have antifungal activity, such as protease inhibitor antiretroviral drugs. This study investigated the in vitro susceptibility of Histoplasma capsulatum var. capsulatum to saquinavir and ritonavir, and its combination with the antifungal itraconazole. The susceptibility assay was performed according to Clin...
Simvastatin inhibits planktonic cells and biofilms ofCandida and Cryptococcussp...
Brilhante,Raimunda Sâmia Nogueira; Caetano,Erica Pacheco; Oliveira,Jonathas Sales de; Castelo-Branco,Débora de Souza Collares MaiaABSTRACTThe antifungal activity of some statins against different fungal species has been reported. Thus, at the first moment, the in vitro antifungal activity of simvastatin, atorvastatin and pravastatin was tested againstCandida spp. and Cryptococcus spp. Then, in a second approach, considering that the best results were obtained for simvastatin, this drug was evaluated in combination with antifungal drugs ag...
Macrobrachium amazonicum: an alternative for microbiological monitoring of aqua...
Brilhante,Raimunda Sâmia Nogueira; Paiva,Manoel de Araújo Neto; Sampaio,Célia Maria de Souza; Teixeira,Carlos Eduardo Cordeiro; Ribeiro,Joyce FontelesThis study aimed to evaluate the role of the Amazon River prawn, Macrobrachium amazonicum, as carrier of Candida spp., by analyzing the correlation between Candida spp. from these prawns and their environment (surface water and sediment), through M13-PCR fingerprinting and RAPD-PCR. For this purpose, 27 strains of Candida spp. were evaluated. These strains were recovered from the gastrointestinal tract of adult...
Moringa oleifera inhibits growth of Candida spp. and Hortaea werneckii isolated...
Rocha,Marcos Fábio Gadelha; Alencar,Lucas Pereira de; Brilhante,Raimunda Sâmia Nogueira; Sales,Jamille de Alencar; Ponte,Yago Brito deThis study aimed to evaluate the antifungal activity of M. oleifera extracts against fungi isolated from farmed prawns and test the toxicity of the extracts on larvae of Macrobrachium amazonicum. The ethanol extracts of pods, seeds, leaves, stems and flowers and chloroform extract of flowers of M. oleifera were tested against 14 strains of Candida spp. and 10 strains of Hortaea werneckii isolated from farming w...
Extratos de Moringa oleifera e Vernonia sp. sobre Candida albicans e Microsporu...
Rocha,Marcos Fábio Gadelha; Aguiar,Franscisco Léo Nascimento de; Brilhante,Raimunda Sâmia Nogueira; Cordeiro,Rossana de AguiarO aumento da incidência das infecções fúngicas, bem como o registro crescente de resistência e falha terapêutica, têm impulsionado a realização de estudos de prospecção de fitoquímicos com propriedades antifúngicas. Diante do exposto, o presente estudo investigou o potencial antifúngico de extratos de Baccharis ligustrina, B. schultzii, Croton jacobinensis, Licania rigida, Moringa oleifera, Vernonia sp. e V. br...
Candidose na medicina veterinária: um enfoque micológico, clínico e terapêutico
Brito,Erika Helena Salles de; Fontenelle,Raquel Oliveira dos Santos; Brilhante,Raimunda Sâmia Nogueira; Cordeiro,Rossana de AguiarO gênero Candida é composto por leveduras que vivem como comensais na microbiota de homens e animais. Em geral, não causam nenhum dano aos seus hospedeiros, entretanto, em virtude de desequilíbrios nas defesas química, física e imunológica, esses microrganismos podem se tornar patogênicos. Infecções por Candida spp. são pouco frequentes na Medicina Veterinária no entanto, nos últimos anos, tem sido observado au...
Chemical composition, toxicity and larvicidal and antifungal activities of Pers...
Leite,João Jaime Giffoni; Brito,Érika Helena Salles; Cordeiro,Rossana Aguiar; Brilhante,Raimunda Sâmia Nogueira; Sidrim,José Júlio CostaThe present study had the aim of testing the hexane and methanol extracts of avocado seeds, in order to determine their toxicity towards Artemia salina, evaluate their larvicidal activity towards Aedes aegypti and investigate their in vitro antifungal potential against strains of Candida spp, Cryptococcus neoformans and Malassezia pachydermatis through the microdilution technique. In toxicity tests on Artemia s...
Successive mycological nail tests for onychomycosis: a strategy to improve diag...
Meireles,Tereza Elizabeth Fernandes; Rocha,Marcos Fábio Gadelha; Brilhante,Raimunda Sâmia Nogueira; Cordeiro,Rossana de Aguiar; Sidrim,José Júlio CostaOnychomycosis is a fungal infection of nails caused by dermatophytes, yeasts and moulds, accounting for about 50% of onychopathies. A high frequency of onychomycosis caused by Candida species has been reported during the last few years in northeast Brazil, as well as in other regions of the world. A clinical diagnosis of onychomycosis needs to be confirmed through laboratory exams. We evaluated the importance o...
