Evaluating the Co-commensal Lifestyles of Staphylococcus aureus and Staphylococcus epidermidis
Staphylococcus epidermidis is a ubiquitous skin commensal, and produces a serine protease Esp that can eradicate nasal carriage of the opportunistic pathogen, Staphylococcus aureus. We evaluated the ability of S. epidermidis and S. aureus to express serine protease and compete with one another in …

Epidemiologische und molekulare Untersuchungen zur Biofilmbildung in Staphylococcus epidermidis und Staphylococcus aureus
Staphylococcus aureus und Staphylococcus epidermidis gehören zu den häufigsten Erregern nosokomialer Infektionen bei immunsupprimierten Patienten. Gleichzeitig bilden diese Bakterien einen wesentlichen Teil der gesunden Hautflora des Menschen. Bisher ist wenig darüber bekannt, ob es Unterschiede in …

The effect of Staphylococcus epidermidis on the pH and dissolution of substitute bone graft materials
… of this study was to determine the effect of S. epidermidis 11047 on the pH and dissolution of 5 different bone substitute materials. Part 1 – Measured the pH, calcium and phosphate of the culture medium in the presence and absence of the 5 bone substitute materials before and after autoclaving. …

Investigating the effect of Staphylococcus epidermidis on the growth dynamics of Staphylococcus aureus in atopic dermatitis
… inconsistencies in the interactions between Staphylococcus epidermidis and Staphylococcus aureus concerning growth and biofilm formation outcomes. This suggests that there might be a strain-level role played by the bacteria that affect the outcomes of their interactions, and consequently, the …

Molecular investigation of the influence of environmental factors and subinhibitory antibiotic concentrations on the biofilm formation in Staphylococcus epidermidis
… is an important step in the pathogenesis of S. epidermidis polymer-associated infections and depends on the expression of the icaADBC operon leading to the synthesis of a polysaccharide intercellular adhesin (PIA). The PIA represents a sugar polymer consisting of ß-1,6 linked N-acetyl …

Genetic and phenotypic diversity of bloodstream associated Staphylococcus epidermidis isolates obtained from private and public hospitals in South Africa
Staphylococcus epidermidis is a commensal bacterium commonly implicated in bloodstream infections. Most S. epidermidis infections are acquired in hospitals and are associated with the use of medical devices. In contrast to its more virulent relative Staphylococcus aureus, S. epidermidis is often …

Study of the effect of mechanical stiffness substrata, assembled with polyelectrolyte multilayer thin films, on biofilm forming staphylococcus epidermidis' initial adhesion mechanism
… the response of biofilm forming staphylococci epidermidis. The formation of biofilms on medical device surfaces is currently responsible for a significant amount of infections acquired in hospitals. Currently mechanisms responsible for the initial adhesion of bacteria are not completely …

The Bactericidal Activity of Human Polymorphonuclear Leukocytes Before and After the Ingestion of Glucose
… a blood sample was drawn and incubated with Staphylococcus epidermidis for 120 minutes. There was no significant difference in the bactericidal activity of leukocytes of blood two hours following the ingestion of glucose from the bactericidal activity of fasting blood. A count done …
