Evaluation of antioxidant therapy in experimental Chagas disease

Abstract INTRODUCTION: Stimulation of inflammatory mediators such as cytokines and chemokines may cause oxidative stress in Chagas disease. In this study, we evaluated the merit of vitamins C and E as antioxidant therapy to minimize the oxidative stress-induced damage in an experimental model of Chagas...

Presencia de estafilococos coagulasa positiva ambientales, su relación clonal, factores de resistencia y habilidad para formar biopelícula
Presence of environmental coagulase-positive staphylococci, their clonal relationship, resistance factors and ability to form biofilm

Rev. argent. microbiol; 49 (1), 2017
Coagulase-positive staphylococci (CoPS) are opportunistic pathogens carrying various mechanisms of resistance that have a large number of virulence factors, and whose ability to induce illness is associated with the host. This study aimed to investigate the presence of environmental coagulase-positive st...

Bioprospección de la actividad antimicrobiana de los extractos de los hongos endófitos de Bauhinia guianensis
Bioprospecting of antimicrobial activity of extracts of endophytic fungi from Bauhinia guianensis

Rev. argent. microbiol; 49 (1), 2017
Antibiotic resistance results in higher medical costs, prolonged hospital stays and increased mortality and is rising to dangerously high levels in all parts of the world. Therefore, this study aims to search for new antimicrobial agents through bioprospecting of extracts of endophytic fungi from Bauhini...

Primer relevamiento de marcadores de resistencia a antibióticos en Enterobacteriaceae en Cochabamba, Bolivia
First survey on antibiotic resistance markers in Enterobacteriaceae in Cochabamba, Bolivia

Rev. argent. microbiol; 49 (1), 2017
A molecular survey was conducted in Cochabamba, Bolivia, to characterize the mechanism involved in the resistance to clinically relevant antibiotics. Extended Spectrum β-lactamase encoding genes and plasmid-mediated quinolone resistance (PMQR) markers were investigated in a total of 101 oxyimino-cep...

Acute amiodarone toxicity causing respiratory failure

Summary A 66-year-old male patient was referred to our clinic with severe pneumonia. Bronchoscopy was performed due to clinical worsening despite antibiotics and diuretic therapy, respiratory failure and radiographic progression. Because bacterial cultures of the bronchoalveolar lavage fluid were negativ...
