Daptomycin versus Vancomycin for Empiric Treatment of Methicillin-Resistant S. aureus among Hospitalized Patients: An Institutional Cost-Breakpoint Analysis
Background: Bacteremia caused by methicillin-resistant Staphylococcus aureus is associated with increased hospitalization days, costs, and mortality. Daptomycin was shown to be noninferior to vancomycin in a phase III clinical trial; however the study was limited by low rates of MRSA infection and …

The role of superantigens during Staphylococcus aureus nasal colonization and infection
… of nasal colonization as well as a model of bacteremia. Compared to wild-type S. aureus COL and Newman, the SAg-deletion mutants COL Δseb and Newman Δsea were able to establish higher bacterial loads in the nose, suggesting that SAgs are involved in regulating bacterial densities during …

The systemic inflammatory response to dental plaque
Introduction: Bacteremia involving oral bacteria and the systemic inflammatory responses are mechanisms that could causally link oral and systemic diseases. Objective: To use an experimental gingivitis model (EGM) in 2 clinical studies to 1) examine the systemic inflammatory responses to dental …

Microbial, metabolic and molecular determinants of neonatal mortality in the rural areas of Limpopo Province, South Africa: umblical cord blood metabolomic profile and bacterial anaysis and their association with perinatal complications
… Additionally, bloodstream infection (bacteremia) prevalence, as detected by culture-dependent and 16S rRNA PCR assays, was recorded at 30.23% and 26.36%, respectively. The majority of culture-confirmed bacterial isolates (58.06%) were gram-positive, with S. epidermidis (36.73%) and S. …

Characterizing the oligomeric structure and catalytic activity of the dihydroorotase and aspartate transcarbamoylase from the bacterium, <i>bacillus anthracis</i>
<p>Bacteremia refers to bacterial presence in the blood. Bacterial proliferation in the blood requires that the organism adapt its metabolism to available nutrients. Nucleotide precursors that could be used are present at low levels in the blood, and thus the invading bacteria must rely on <em>de …

THE ROLE OF BACTERIAL AMYLOID FIBRILS IN ESCHERICHIA COLI COMPLEMENT RESISTANCE
… causes human disease, many strains which cause bacteremia have been identified as possessing virulence factors which make them more resistant to the complement system. The bacterial amyloid fibril, curli, functions in bacterial adherence and the formation of biofilm. Curli-producing parental and …
