Staphylococcus aureus subsp. aureus ATCC 25923 is commonly used as a control strain for susceptibility testing to antibiotics and as a quality control strain for commercial products. We present the completed genome sequence for the strain, consisting of the chromosome and a 27.5-kb plasmid.

Purulent infection of a surgical wound developed after discectomy, and a mannitol-nonfermenting Staphylococcus aureus isolate was cultivated as the etiologic agent. Nonfermenting S. aureus strains are exceedingly rare and may be erroneously mistaken and dismissed as contaminants. This report then emphasizes that pure and massive cultures must be carefully evaluated, even if preliminary examinat...

Both bacterial and host factors contribute to complicated bloodstream infection (BSI) caused by Staphylococcus aureus including methicillin-resistant S. aureus (MRSA). One bacterial factor that may affect the persistence of S. aureus in complicated BSI is reduced susceptibility to the innate immune defence peptide LL-37. LL-37 susceptibility among S. aureus isolates causing uncomplicated and co...

Four studies assessed the frequency of vaginal Staphylococcus aureus colonization in healthy women and associated risk factors. An association was found between S. aureus vaginal colonization and colonization at the labia minora and the anterior nares. Significant risk factors associated with an increased risk of vaginal S. aureus in at least one study were a history of genital herpes simplex i...

The Gram-positive bacterium Staphylococcus aureus is a human pathogen increasingly causing severe infections, especially in hospital environments. Moreover, strains which are resistant against various types of antibiotics are developing and spreading widely as in the case of the community-acquired MRSA (methicillin resistant S. aureus). In this study metabolic glycoengineering with N-azidoacety...

Bacterium-platelet interactions at the cardiac valve surface represent an important initial step in the induction of infective endocarditis (IE). This cell-cell interaction may play either a protagonistic role in the induction of IE via bacterial adherence to and aggregation of platelets or an antagonistic role via secretion of platelet-derived microbicidal molecules. We examined the spectrum a...

The objectives of the present study were to investigate the rate of S.aureus nasal carriage and molecular characteristics in hospital and community settings in Bobo Dioulasso, Burkina Faso. Nasal samples (n = 219) were collected from 116 healthy volunteers and 103 hospitalized patients in July and August 2014. Samples were first screened using CHROMagar Staph aureus chromogenic agar plates, and...

Different clones of methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus have been found in humans as well as in animals and retail meat. However, more information about the genetic characteristics and similarities between strains is needed. The aim of this study was to identify and characterize Staphylococcus aureus from humans, and to compare their characteris...

BACKGROUND When Staphylococcus aureus is isolated in urine, it is thought to usually represent hematogenous spread. Because such spread might have special clinical significance, we evaluated predictors and outcomes of S. aureus bacteriuria among patients with S. aureus bacteremia. METHODS A case-control study was performed at John H. Stroger Jr. Hospital of Cook County among adult inpatients ...

BACKGROUND Glycerol monolaurate (GML), a 12 carbon fatty acid monoester, inhibits Staphylococcus aureus growth and exotoxin production, but is degraded by S. aureus lipase. Therefore, dodecylglycerol (DDG), a 12 carbon fatty acid monoether, was compared in vitro and in vivo to GML for its effects on S. aureus growth, exotoxin production, and stability. METHODOLOGY/PRINCIPAL FINDINGS Antimicro...
