Biofilms of Candida spp. from the ocular conjunctiva of horses with reduced azo...
Brilhante, Raimunda Sâmia Nogueira; Bittencourt, Paula Vago; Castelo-Branco, Debora de Souza Collares; Guedes, Glaucia Morgana de MeloObjectives This study aimed to assess the biofilm-forming ability of Candida spp. from the ocular conjunctiva of horses and to investigate the antifungal susceptibility of these biofilms. Procedures Initially, the biofilm-forming ability of 15 strains was assessed by crystal violet staining, which reveals the fungal biomass adhered to the polystyrene plates, and scanning electron microscopy. Then, the minimum i...
Research advances on the multiple uses of Moringa oleifera : a sustainable alte...
Brilhante, Raimunda Sâmia Nogueira; Sales, Jamille Alencar; Pereira, Vandbergue Santos; Castelo-Branco, Débora de Souza Collares MaiaMoringa oleifera Lam (Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for the...
Tumor necrosis factor prevents Candida albicans biofilm formation
Rocha, Francisco Airton Castro; Alves, Anelise Maria Costa Vasconcelos; Rocha, Marcos Fábio Gadelha; Cordeiro, Rossana de Aguiar CordeiroCandida species are commensals but some develop biofilms in prosthetic materials and host surfaces that may represent up to 30% of deaths related to infections, particularly in immunosuppressed patients. Tumor necrosis factor (TNF) exhibits a plethora of functions in host defense mechanisms whereas excessive release of TNF in inflammation promotes tissue damage. Cytokines released in an inflammatory milieu may ...
Aeromonas and Plesiomonas species from scarlet ibis ( Eudocimus ruber ) and the...
Castelo-Branco, Débora Souza Collares Maia; Silva, Aline Lobão da; Monteiro, Frederico Ozanan Barros; Guedes, Glaucia Morgana de MeloThe present study aimed at evaluating the role of captive scarlet ibises (Eudocimus ruber) and their environment as reservoirs of Aeromonas spp. and Plesiomonas spp., and analyzing the in vitro antimicrobial susceptibility and virulence of the recovered bacterial isolates. Thus, non-lactose and weak-lactose fermenting, oxidase positive Gram-negative bacilli were recovered from cloacal samples (n = 30) of scarle...
Antiretroviral drugs saquinavir and ritonavir reduce inhibitory concentration v...
Brilhante, Raimunda Sâmia Nogueira; Caetano, Érica Pacheco; Riello, Giovanna Barbosa Riello; Guedes, Glaucia Morgana de MeloRecent studies have shown that some drugs that are not routinely used to treat fungalinfections have antifungal activity, such as protease inhibitor antiretroviral drugs. This studyinvestigated the in vitro susceptibility of Histoplasma capsulatum var. capsulatum to saquinavirand ritonavir, and its combination with the antifungal itraconazole. The susceptibility assaywas performed according to Clinical and Labo...
Cross-resistance to fluconazole induced by exposure to the agricultural azole t...
Rocha, Marcos Fabio Gadelha; Alencar, Lucas Pereira de; Araújo Neto, Manoel Paiva de; Melo, Luciana Magalhães; Bandeira, Silviane Praciano; Ponte, Y. B.This study aimed to investigate the influence of tetraconazole and malathion, both used in agricultural activities, on resistance to fluconazole, itraconazole and voriconazole in Candida parapsilosis ATCC 22019. The susceptibility to tetraconazole, malathion, fluconazole, itraconazole and voriconazole, through broth microdilution. Then, 12 independent replicates, were separated and exposed to four treatment gro...
Antifungal resistance and virulence among Candida spp. from captive amazonian m...
Sidrim, José Júlio Costa; Carvalho, Vitor Luz; Castelo-Branco, Débora de Souza Collares Maia; Brilhante, Raimunda Sâmia NogueiraThis work aimed at evaluating the antifungal susceptibility and production of virulence factors by Candida spp. isolated from sirenians in Brazil. The isolates (n = 105) were recovered from the natural cavities of Amazonian and West Indian manatees and were tested for the susceptibility to amphotericin B, itraconazole, and fluconazole and for the production of phospholipases, proteases, and biofilm. The minimum...
Enterobacteria and Vibrio from Macrobrachium amazonicum prawn farming in Fortal...
Castelo-Branco, D ebora de Souza Collares Maia; Sales, Jamille Alencar; Brilhante, Raimunda Sâmia Nogueira; Guedes, Glaucia Morgana de MeloObjective: To investigate the isolation of enterobacteria associated with Macrobrachium amazonicum (M. amazonicum) farming and evaluate the in vitro antimicrobial susceptibility of Vibrio strains. Methods: Strains were isolated from female M. amazonicum prawns and environmental and hatchery water. Biochemical assays were used to identify bacterial genera and those belonging to the genus Vibrio were submitted to...
Vibrio spp. from Macrobrachium amazonicum prawn farming are inhibited by Moring...
Brilhante, Raimunda Sâmia Nogueira; Sales, Jamille Alencar; Sampaio, Celia Maria de Souza; Barbosa, Francisco Geraldo; Paiva, Manoel de Araújo NetoObjective To investigate the in vitro antimicrobial potential of extracts of stem, leaves, flowers, pods and seeds of Moringa oleifera (M. oleifera) against Vibrio spp. from hatchery water and the prawn Macrobrachium amazonicum. Methods The ethanol extracts of stem, leaves, pods and seeds and chloroform extract of flowers of M. oleifera were tested against Vibrio cholerae (V. cholerae) serogroups non-O1/non-O13...
In vitro inhibitory activity of terpenic derivatives against clinical and envir...
Brilhante, Raimunda Sâmia Nogueira; Marques, Natalya Fechine Silva; Castelo-Branco, Débora de Souza Collares Maia; Lima, Rita Amanda Chaves deSporotrichosis is a subacute or chronic subcutaneous infection, caused by the fungus Sporothrix schenkii complex, occurring in human and animal tissues. Potassium iodide and itraconazole have been used as effective therapy for first-choice treatment, while am- photericin B may be indicated for disseminated infection. However, the adverse effects of potassium iodide and amphotericin B or the long duration of the...
