Geobacillus stearothermophilus T-6 is a thermophilic soil bacterium that has a 38-kb gene cluster for the utilization of arabinan, a branched polysaccharide that is part of the plant cell wall. The bacterium encodes a unique three-component regulatory system (araPST) that includes a sugar-binding lipoprotein (AraP), a histidine sensor kinase (AraS), and a(More)
BACKGROUND Carbapenem-resistant Enterobacteriaceae, especially Klebsiella spp., have become a major health problem recently worldwide. Since 2006 the incidence of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections has increased substantially in Israel. Bloodstream infections (BSIs) caused by these strains have been associated with high rates of(More)
Antibiotic de-escalation is an appealing strategy in antibiotic stewardship programmes. We aimed to assess its safety and effects using a systematic review and meta-analysis. We included randomized controlled trials (RCTs) and observational studies assessing adults with bacteraemia, microbiologically documented pneumonia or severe sepsis, comparing between(More)
BACKGROUND Finegoldia magna (F. magna) is a rare pathogen causing infective endocarditis (IE). Only 7 cases are documented in the literature. CASE REPORT We report a case of infective endocarditis in a 45-year-old male due to F. magna 2 months after a Bentall procedure. He presented with fever, dyspnea, and chest pain. Aerobic and anaerobic blood samples(More)
The beneficial effects of eplerenone, a specific mineralocorticoid receptor blocker, were previously demonstrated in early atherosclerosis (ATS). The aim of the present study was to evaluate the effect of eplerenone in advanced versus early ATS. Apolipoprotein E knockout mice aged 16 or 32 weeks were randomly divided into eplerenone (100 mg·kg·d) or vehicle(More)
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) are emerging. In attempt to eradicate CRE colonization, we conducted a semirandomized, prospective, controlled trial using oral nonabsorbable antibiotics. METHODS Consecutive hospitalized CRE carriers were studied. Patients whose rectal isolates were gentamicin sensitive but colistin resistant were(More)
Carbapenem-resistant Acinetobacter baumannii has been increasingly reported as the causative agent of ventilator-associated pneumonia (VAP) among patients in the intensive care units. However, there are insufficient data to guide the appropriate treatment for such infection. Our aim was to compare the outcome of carbapenem-resistant A. baumannii VAP treated(More)
Release of antimicrobial agents from bone healing devices can dramatically reduce the risk of implant-associated infection. Here we report the fabrication and antimicrobial activity of a multifunctional load-bearing bioresorbable material that can provide mechanical support to the healing bone all while slowly releasing an antibiotic drug. Dense(More)
INTRODUCTION A low-sodium diet (LSD) was shown to increase both angiotensin II (AngII) and aldosterone levels, and to accelerate atherosclerosis in apolipoprotein E-deficient (E0) mice. The aim of the present study was to examine whether accelerated atherosclerosis in E0 mice fed a LSD is mediated by aldosterone, using the mineralocorticoid receptor(More)
Bloodstream infections (BSI) and sepsis are among the most common complications occurring in severe burn patients. This study was designed to evaluate changes in BSI pathogens over almost a decade in severe burn patients at Rambam Healthcare Campus, and BSI occurrence during early and late hospitalization periods. Retrospective computerized data was(More)
