OBJECTIVES Staphylococcus aureus colonization of the skin and the nostrils remains a major cause of surgical-site infections despite preoperative and preventive procedures. To date, many compounds have been used for S. aureus decolonization, including mupirocin ointments and antiseptics, with variable results. The emergence of mupirocin-resistant S. aureus strains has led to the search for new ...
1 2 The cell surface-associated extracellular adherence protein (Eap) mediates adherence of 3 Staphylococcus aureus to host extracellular matrix components, and inhibits inflammation, 4 wound healing and angiogenesis. A well-characterized collection of S. aureus and non5 S. aureus staphylococcal isolates (n = 813) was tested for the presence of the Eap-encoding 6 gene (eap) by PCR to investigat...
BACKGROUND Clumping factor A (ClfA) is a Staphylococcus aureus cell wall-associated adhesin that mediates staphylococcal binding to fibrinogen and platelets. Our goals were to determine whether expression of capsular polysaccharide (CP) affected ClfA-mediated adherence of S. aureus and to assess whether the length of the ClfA repeat region influenced this interaction. METHODS ClfA constructs ...
Among athletes, Staphylococcus aureus is thought to be transmitted by close physical contact with carriers. Nevertheless, evidence is limited with regard to both the tracking of individual strains and the role of S. aureus on the skin's surface. We investigated its transmission using molecular genotyping and the presence of S. aureus on the skin during exercise. In the first study, nasal sample...
Staphylococcus aureus (S. aureus) is one of the most common causes of biofilm infections in periprosthetic joint infections (PJIs). Accumulating evidence has shown that the immunosuppressive environment established by S. aureus biofilm infection in PJIs involves the presence of myeloid-derived suppressor cells (MDSCs) and M2-macrophages. Due to the diversity of MDSCs, little is known about whet...
Selective digestive decontamination (SDD, topical antibiotic regimens applied to the respiratory tract) appears effective for preventing ventilator associated pneumonia (VAP) in intensive care unit (ICU) patients. However, potential contextual effects of SDD on Staphylococcus aureus infections in the ICU remain unclear. The S. aureus ventilator associated pneumonia (S. aureus VAP), VAP overall ...
Invasive disease following methicillin-resistant Staphylococcus aureus (MRSA) detection is common, regardless of whether initial detection involves colonization or infection. We assessed the genetic relatedness of isolates obtained > or =2 weeks apart representing either repeated infections or colonization-infection sets to determine if infections are likely to be caused by previously harbored ...
The airways of cystic fibrosis (CF) patients have thick mucus, which fosters chronic, polymicrobial infections. Pseudomonas aeruginosa and Staphylococcus aureus are two of the most prevalent respiratory pathogens in CF patients. In this study, we tested whether P. aeruginosa influences the susceptibility of S. aureus to frontline antibiotics used to treat CF lung infections. Using our in vitro ...
Background and Aim: Pemphigus is a chronic autoimmune blistering disease characterized by intraepidermal blisters. These blisters damage the skin barrier and increase the risk of life-threatening infections. Nasal colonization of Staphylococcus aureus can increase the risk of infections and delay the wound healing process.The aim of this study was to determine the frequency of staphylococcal...
