  1. 1. Structural studies of the surface adhesin SspB from Streptococcus gordonii

    University dissertation from Umeå : Umeå universitet

    Author : Nina Forsgren; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus gordonii; X-ray crystallography; surface adhesin; dental plaque; structural biology; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Abstract : Surface proteins on microorganisms that build up the oral biofilm are key players in the formation of the biofilm. Antigen I/II proteins are surface adhesins found on virtually all oral streptococci and share a conserved multi-domain architecture. These adhesins bind surface components on other bacteria and on host cells. READ MORE

  2. 2. Surface proteins of pathogenic streptococci

    University dissertation from Divison of Medical Microbiology

    Author : Thomas Areschoug; Lunds universitet.; Lund University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; 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

  3. 3. Surface expression using the AIDA autotransporter  Towards live vaccines and whole-cell biocatalysis

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martin Gustavsson; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AIDA-autotransporter; Escherichia coli; live vaccines; surface expression;

    Abstract : The area of surface expression has gathered a lot of interest from research groups all over the world and much work is performed in the area. Autotransporters have been used for surface expression in Gram-negative bacteria. READ MORE

  4. 4. Effect of surface characteristics on cellular adherence and activity

    University dissertation from Malmö University, Faculty of Odontology

    Author : Marjan Dorkhan; Malmö University.; [2014]
    Keywords : ODONTOLOGY; ODONTOLOGI; Sciences; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

    Abstract : After insertion of the dental implant into the jaw, the neck of the implant protruding through the mucosa (implant abutment) will be exposed to the complex environment of the mouth. This results in the formation of a conditioning protein coat (pellicle) derived from saliva and/or gingival crevicular fluid. READ MORE

  5. 5. Helicobacter pylori adhesion and patho-adaptation the role of BabA and SabA adhesins in persistent infection and chronic inflammation

    University dissertation from Malmö University, Faculty of Odontology

    Author : Jafar Mahdavi; Umeå universitet.; [2004]
    Keywords : H. pylori; BabA; adhesin; Lewis b; MUC5AC; sialyl-dimeric-Lewis x; chronic inflammation; SabA; Lewis x; LPS; odontologi; Odontology;

    Abstract : Helicobacter pylori (H. pylori) is a human-specific gastric pathogen which is responsible for a spectrum of diseases ranging from superficial gastritis to gastric and duodenal ulceration, and which is also highly associated with gastric cancer. The pathogenesis of severe gastric disorders caused by H. READ MORE
