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 …

Virulenz und Resistenzspektrum von Staphylococcus epidermidis im experimentellen Modell der Endophthalmitis
… dar. Häufig wird Staphylococcus epidermidis nachgewiesen. Für die Visusprognose entscheidend sind eine prompte Diagnose und schnellstmögliche Therapieeinleitung, um eine rasche Beseitigung der Erreger und Suppression der Immunantwort zu erreichen. Für die gezielte Therapie einer …

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
… 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 …

S. epidermidis putative toxin-antitoxin module mazEF: the role in VBNC formation and impact on the immune system
Staphylococcus epidermidis é um microrganismo comensal que habita na pele e membranas mucosas dos seres humanos e outros mamíferos, mas que pode atuar como um agente patogénico oportunista, especialmente em pacientes imunocomprometidos e em bebés prematuros. Os principais fatores de virulência de …

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 …

Die Rolle des bakteriellen Insertionselements IS256 bei der Modulation der Biofilmbildung in Staphylococcus epidermdis
Staphylococcus epidermidis zählt zu den häufigsten Erregern nosokomialer Infektionen im Zusammenhang mit implantierten Fremdkörpern. Diese Bakterien zeigen eine außergewöhnliche phänotypische und genotypische Variabilität, von der auch die Expression wichtiger virulenz- und resistenzassoziierter …

Interaction of skin cells with skin microbiota
… wound healing. On the other hand, Staphylococcus epidermidis, as a skin commensal, has been shown to protect the skin against pathogens. Therefore, this study aims to investigate the effect of skin commensal bacteria on the skin cells and the opportunistic bacteria inhabiting the skin. The effect …

Does the human skin microbiome adapt to antibiotic exposure?
Staphylococcus epidermidis is a substantial element of the healthy human skin microflora and can become pathogenic to cause infections, for example, septicaemia and endocarditis. The effects of long-term sub-lethal exposure to antibiotics on the skin microbiota are unknown. How does antibiotic …

Prevention of bacterial growth in platelet products via inclusion of iron chelators
… we first assessed growth of Staphylococcus epidermidis in culture medium after treatment with the iron chelators deferoxamine (DFO) or phytic acid. DFO significantly inhibited bacterial growth in a dose dependent manner (p < 0.009). Conversely, phytate only inhibited bacterial growth at …

Lineage-level within-species dynamics in the human facial skin microbiome
… and delineate 4,055 genomes of C. acnes and S. epidermidis isolates from human facial skin into 167 lineages. In Chapter 3, I use these data to observe natural transmission events and assembly dynamics of the facial skin microbiome. I find that the gain and loss of individual C. acnes and S. …
