Autor: Ana Lúcia Souza Antunes, Jéssica Weis Bonfanti, Leandro Reus Rodrigues Perez, Camille Cattani Ferreira Pinto, Ana Lúcia Peixoto de Freitas, Alexandre José Macedo, Afonso Luis Barth
Publikováno v: Memorias do Instituto Oswaldo Cruz, Vol 106, Iss 1, Pp 51-55 (2011)
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. Here, we determined the minima

Autor: Ana Lúcia Souza Antunes, Carina Secchi, Keli Cristine Reiter, Leandro Reus Rodrigues Perez, Ana Lúcia Peixoto de Freitas, Pedro Alves d'Azevedo
Publikováno v: Memorias do Instituto Oswaldo Cruz, Vol 102, Iss 6, Pp 719-723 (2007)
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 in over 80% of isolates, and

When the resistance gets clingy: Pseudomonas aeruginosa harboring metallo-β-lactamase gene shows high ability to produce biofilm
Autor: Ana Lúcia Peixoto de Freitas, Afonso Luis Barth, Leandro Reus Rodrigues Perez, Ana Lúcia Souza Antunes
Publikováno v: European Journal of Clinical Microbiology & Infectious Diseases. 31:711-714
The ability to produce biofilm and the presence of metallo-β-lactamase (MBL) among Pseudomonas aeruginosa isolates were evaluated. A total of 91 isolates were recovered from sputa of patients with (CF, n = 44) and without (non-CF, n = 47) cystic fib

Publikováno v: APMIS. 118:873-877
The aim of this study was to use a practical method to determine the minimal biofilm eradication concentration (MBEC) of vancomycin and to compare the MBEC with minimal inhibitory concentration (MIC) for biofilm-producing and non-biofilm-producing is

Publikováno v: Journal of Clinical Microbiology. 50:2506-2508
We evaluated the use of a chromogenic selective medium (MRSA ID) as a useful tool for the detection of methicillin-resistant Staphylococcus aureus (MRSA) in cystic fibrosis (CF) patient samples. Fifty-four MRSA isolates were detected by MRSA ID, whil

Publikováno v: Brazilian Journal of Infectious Diseases, Vol 12, Iss 4, Pp 316-320
The NCCLS (2004) presented a new methodology to detect, by disk-diffusion agar, oxacillin-resistance using a cefoxitin disk. We identified coagulase-negative staphylococci (SCoN) to the species level and compared the use of cefoxitin disks (30 µg) w

Publikováno v: Medicinal chemistry (Shariqah (United Arab Emirates)). 10(3)
Staphylococcus epidermidis, a commensal microorganism at the human skin and mucosae, is nowadays considered an important opportunistic pathogen related to nosocomial infections on indwelling medical devices due biofilm formation. Bacterial biofilms a
