An alternative method for the analysis of melanin production in Cryptococcus ne...
Brilhante, Raimunda S. N.; España, Jaime D. A.; Alencar, Lucas Pereira de; Pereira, Vandbergue S.; Castelo-Branco, Débora de S. C. M.Melanin is an important virulence factor for several microorganisms, including Cryptococcus neoformans sensu lato and Cryptococcus gattii sensu lato, thus, the assessment of melanin production and its quantification may contribute to the understanding of microbial pathogenesis. The objective of this study was to standardise an alternative method for the production and indirect quantification of melanin in C. ne...
β-Lactam antibiotics and vancomycin inhibit the growth of planktonic and biofil...
Sidrim, José J.C.; Teixeira, Carlos E.C.; Cordeiro, Rossana A.; Brilhante, Raimunda S.N.; Castelo-Branco, Débora S.C.M.; Bandeira, Silviane P.The aim of this study was to evaluate the effects of cefepime, meropenem, piperacillin/tazobactam (TZP) and vancomycin on strains of Candida albicans and Candida tropicalis in planktonic and biofilm forms. Twenty azole-derivative-resistant strains of C. albicans (n = 10) and C. tropicalis (n = 10) were tested. The susceptibility of planktonic Candida spp. to the antibacterial agents was investigated by broth mi...
Yeast microbiota of raptors : a possible tool for environmental monitoring
Brilhante, Raimunda S. N.; Castelo Branco, Débora S. C. M.; Duarte, Guilherme P. S.; Paiva, Manoel de Araújo Neto; Monteiro, André J.Twenty-two raptors from a rehabilitation centre were evaluated for the presence of yeasts prior to returning them to the wild, and the recovered Candida isolates were tested for in vitro antifungal susceptibility and phospholipase production. Samples were collected from the crop/lower esophagus and cloaca. In vitro antifungal susceptibility and phospholipase production of 21 Candida strains were assessed throug...
Clinical-epidemiological features of 13 cases of melioidosis in Brazil
Brilhante, Raimunda S. N.; Bandeira, Tereza J. P. G.; Cordeiro, Rossana A.; Grangeiro, Thalles Barbosa; Lima, Rita A. C.; Ribeiro, Joyce F.he aim of this work was to catalog the clinical and ecoepidemiological characteristics of melioidosis in Brazil. The clinical-epi- demiological features of melioidosis in Ceará are similar to those in other regions where the disease is endemic. These findings support the inclusion of this Brazilian state as part of the zone of endemicity for melioidosis
