2. 1. Molecular studies on streptococcal surface proteins

   Author : Johan Waldemarsson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonimmunodominance; vaccine; camouflaging; Streptococcus agalactiae; leucine-rich repeat; Streptococcus pyogenes; alpha; fibrinogen; M protein; surface proteins; Rib;

   Abstract : Streptococcus agalactiae and Streptococcus pyogenes are two related human pathogens causing different diseases. This thesis focuses on a number of surface proteins expressed by S. agalactiae and S. pyogenes and, more specifically, the molecular and biological characterization of these proteins. READ MORE

4. 2. Surface proteins of pathogenic streptococci

   Author : Thomas Areschoug; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; factor H; complement regulator; CD89; human IgA; protective immunity; surface protein; Streptococcus pyogenes; group B streptococcus;

   Abstract : Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity. READ MORE

5. 3. The impact of Staphylococcus aureus surface proteins on virulence

   Author : Niklas Palmqvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : Staphylococcus aureus; septic arthritis; sepsis; virulence; cell wall-anchored proteins; surface proteins; fibrinogen.;

   Abstract : Staphylococcus aureus is an important pathogen in humans with the potential to cause life-threatening invasive infections, including sepsis and septic arthritis. The pathogenicity of S. aureus depends on the expression of a variety of virulence factors. READ MORE

6. 4. Surface Modification of Biomedical Polyurethanes

   Author : Christina Freij-Larsson; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein adsorption.; surface morphology; adsorption; polymer blends; polymer grafting; amphiphilic polymers; poly ethylene oxide ; Surface modification; polyurethane; Polymer technology; biopolymers; Polymerteknik;

   Abstract : The aim of the this thesis was surface modification of a biomedical polyurethane (PUR), Pellethane 2363-80AE*, to improve the biocompatibility. Surfaces modified by poly(ethylene oxide) (PEO) were prepared either by grafting PEO covalently at the PUR surface by a two-step reaction, or by using amphiphilic polymers containing PEO as the hydrophilic part.

7. 5. Surface proteins of Finegoldia magna interacting with the human host

   Author : Christofer Karlsson; Infektionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finegoldia magna; Gram-positive anaerobic cocci; surface proteins; protease; LL-37; MIG CXCL9; Fibrinogen; adhesion; gene disruption; bacterial aggregation; basement membranes;

   Abstract : Finegoldia magna is a Gram-positive anaerobe and a member of the normal human microflora. This bacterium is also an opportunistic pathogen and isolated from ~10% of all anaerobic infections. Reoccurring taxonomical changes and the anaerobic growth have contributed to the neglect of F. magna. READ MORE
