We sequenced the oldest blaKPC-2-bearing plasmid isolated in Brazil and another plasmid also carried by a Klebsiella pneumoniae strain of sequence type 442 (ST442), isolated 52 months later. Both plasmids present an IncN backbone and few acquired regions. Because the 2005 plasmid presented deletions and a truncated gene within Tn4401b compared to the 2009(More)

The development of novel biological products, such as enzymes, dyes, antibiotics, and others with high potential use for biotechnological applications, continues to stimulate the search for microorganisms in extreme environments. In recent years, the study of Antarctic ecosystems and their microorganisms has received more attention because psychrophilic(More)
Intrinsic mechanisms leading to carbapenem-induced membrane impermeability and multidrug resistance are poorly understood in clinical isolates of Enterobacteriaceae. In this study, molecular behaviours during the establishment of membrane impermeability in members of the Enterobacteriaceae family under imipenem selective pressure were investigated. Clinical(More)
INTRODUCTION Clopidogrel is commonly used in prevention and treatment of atherothrombosis. Some previous studies have suggested a pleiotropic effect of clopidogrel; however, when this drug causes platelet-independent effects on endothelial function remains unclear. AIMS To evaluate the influence of clopidogrel on inflammatory biomarkers and adhesion(More)
