2. 1. Binding of plasma proteins by Staphylococcus epidermidis: characterisation of protein-protein interactions

   Author : Dai-Qing Li; Diabetes - öpatofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; mice and immunisation; biomaterial-associated infections; von Willebrand factor; thrombospondin; clusterin; Staphylococcal receptins; vitronectin; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : Coagulase-negative staphylococci (CoNS), in particular, Staphylococcus epidermidis, have emerged as major nosocomial pathogens associated with infections of implanted medical devices. These organisms, which are among the most prevalent bacteria of the human skin and mucous membrane microflora, gain access to the surface of the implant at the insertion. READ MORE

4. 2. Experimental implant-associated orthopaedic infections

   Author : Åke Johansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Osteomyelitis; anaerobic bacteria; implant design and material; bacterial collagen- and fibronectin-binding;

   Abstract : Although indispensable in today's medicine, orthopaedic implants may also cause adverse reactions. A foreign body increases the local susceptibility to colonisation by microorganisms, and hence the risk of infections. These infections are rare, but many result in prolonged or permanent impairment.

5. 3. On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants

   Author : Magdalena Zaborowska; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osseointegration; amputation prosthesis; implant-associated infection; biofilm; staphylococci; extracellular vesicles; host defence; cytokines; cell death;

   Abstract : Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and colonize implant surfaces. READ MORE

6. 4. Interactions between staphylococci, heparin, heparin dependent growth factors and biomaterials

   Author : Corina Fallgren; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; and biomaterials bonded with antibiotics; heparin-binding growth factors; staphylococci; heparin; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : Resident skin micro-organisms such as S. epidermidis and other coagulase-negative staphylococci (CoNS), are by far the most common causes of biomaterial-associated infections. These micro-organisms often exhibit surface adhesins that specifically bind serum and tissue proteins adsorbed to implanted biomaterials. READ MORE

7. 5. Molecular and cellular interactions on noble metal nanopatterned surfaces − applications towards bone, soft tissue and infection control

   Author : Sara Svensson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanotopography; noble metals; titanium; biocompatibility; osseointegration; inflammation; host defence; monocytes; infection control; antimicrobial; staphylococci;

   Abstract : Biomaterial-associated infection is recognised as one of the main risks for failure of medical devices. The presence of a foreign material in tissues has been suggested to compromise the ability of host cells to eradicate infection. READ MORE
