The phenotypic and genotypic characteristics of clinical and intestinal enterococcal isolates recovered from inpatients and outpatients of two Brazilian hospitals, located in Niterói city, Rio de Janeiro, Brazil, were compared. A total of 601 strains were studied, including 253 isolated from different clinical sources and 348 intestinal strains (205(More)
The presence of the ileS-2 gene, responsible for mupirocin resistance, in clinical isolates of methicillin-resistant Staphylococcus aureus was determined by multiplex polymerase chain reaction. Three pairs of primers were used, which yielded specific fragments of femA (encoding a unique feature of S. aureus), mecA (encoding resistance to methicillin) and(More)
Interpretation of the mupirocin E-test for low-level mupirocin-resistant Staphylococcus aureus strains has been improved by adding the indicator dye tetrazolium. E-tests were compared with agar dilution methods for assessing mupirocin susceptibility. MICs obtained by the agar dilution method and E-tests showed 89.3% agreement within 2 log(2) dilution(More)
CONTEXT AND OBJECTIVES Urinary tract infections are the most common cause of hospital-acquired infections, and the use of indwelling urinary catheters is a predisposing factor for their development. The aims of this study were to estimate the frequency of pre and postoperative bacteriuria, identify the microorganisms involved, count the colony-forming(More)
We report the case of a patient with chronic obstructive pulmonary disease and bronchiectasis, chronically using corticosteroids, who acquired pulmonary nocardiosis, which presented as multiple cavitated nodules. The principal symptoms were fever, dyspnea and productive cough with purulent sputum. Chest X-ray and computed tomography of the chest revealed(More)
INTRODUCTION Acinetobacter spp. have emerged as notorious pathogens involved in healthcare-associated infections. Carbapenems are important antimicrobial agents for treating infections due to multidrug resistant Acinetobacter spp. Different mechanisms may confer resistance to these drugs in the genus, particularly production of class D carbapenemases.(More)
 In this work, mupirocin resistance was correlated with the presence of plasmids in methicillin-resistant Staphylococcus aureus (MRSA) strains isolated in the Rio de Janeiro Federal University Hospital in Brazil, where topical mupirocin has been used extensively since 1990. Of 19 strains studied, those exhibiting high-level resistance carried a large and(More)
INTRODUCTION Acquired production of metallo-β-lactamases is an important mechanism of resistance in Pseudomonas aeruginosa. The objective of this study was to investigate the production of metallo-β-lactamase and the genetic diversity among ceftazidime-resistant P. aeruginosa isolates from State of Sergipe, Brazil. METHODS Metallo-β-lactamase was(More)
