Biofilm production using distinct media and antimicrobial susceptibility profile of Pseudomonas aeruginosa
Perez, Leandro Reus Rodrigues; Barth, Afonso Luis (2011) [Artigo de periódico]Biofilm production is an important mechanism for bacterial survival and its occurrence together with antimicrobial resistance represents a challenge for clinical management. Here, we evaluated the ability for biofilm ... -
Evaluation of biofilm production by pseudomonas aeruginosa isolates recovered from cystic fibrosis and non-cystic fibrosis patients
Perez, Leandro Reus Rodrigues; Costa, M.C.N.; Freitas, Ana Lucia Peixoto de; Barth, Afonso Luis (2011) [Artigo de periódico]Cystic fibrosis (CF) patients typically suffer of persistent and recurrent lung infections caused by Pseudomonas aeruginosa that many times possess ability for the biofilm production. Here, biofilm production among P. ... -
Evaluation of oxacillin and cefoxitin disks for detection of resistance in coagulase negative staphylococci
Antunes, Ana Lucia Souza; Secchi, Carina; Reiter, Keli Cristine; Perez, Leandro Reus Rodrigues; Freitas, Ana Lucia Peixoto de; D'Azevedo, Pedro Alves (2007) [Artigo de periódico]Coagulase-negative Staphylococcus spp. was considered nonpathogenic until the emergence of multiresistance and the demonstration of their participation as infectious agents. In Brazil, oxacillin resistance may be present ... -
Evaluation of tests to predict metallo-B-lactamase in cystic fibrosis (CF) and non-(CF) Pseudomonas
Perez, Leandro Reus Rodrigues; Limberger, Mariana Fagundes; Costi, Ricardo; Dias, Cícero Armídio Gomes; Barth, Afonso Luis (2014) [Artigo de periódico]Double disks synergy test (DDST) and combined disks test (CD) were evaluated to predict the presence of metallo-β-lactamase in 70 Pseudomonas aeruginosa isolates recovered from cystic fibrosis and non-cystic fibrosis ... -
High vancomycin resistance among biofilms produced by staphylococcus species isolated from central venous catheters
Antunes, Ana Lucia Souza; Bonfanti, Jéssica Weis; Perez, Leandro Reus Rodrigues; Pinto, Camille Catani Ferreira; Freitas, Ana Lucia Peixoto de; Macedo, Alexandre José; Barth, Afonso Luis (2011) [Artigo de periódico]Biofilm production is an important mechanism that allows microbes to escape host defences and antimicrobial therapy. Vancomycin has been used largely for the treatment of methicillin-resistant staphylococcal infections. ... -
