  1. 1. HLA, salivary IgA and mutans streptococci - is there a relation?

    University dissertation from Malmö University, Centre for Oral Health Sciences

    Author : Marie-Louise Wallengren; Malmö University.; [2004]
    Keywords : ODONTOLOGY Oral microbiology; ODONTOLOGI Oral mikrobiologi; ODONTOLOGY Cariology; ODONTOLOGI Cariologi; Medicine; Immunoglobulin A; Streptococcus mutans; Streptokocker; Karies;

    Abstract : The aim of the present studies was to investigate a possible relationship between the human leukocyte antigen (HLA) complex, colonization of mutans streptococci and salivary immunoglobulin A (IgA) antibodies against mutans streptococcal antigens. In the first study a strong inverse relationship between HLA-DR4 and levels of mutans streptococci was observed for a group of renal transplant patients (I). READ MORE

  2. 2. Pathogen-host interactions at the surface of Streptococcus pyogenes

    University dissertation from KFS AB

    Author : Patrik Nyberg; Lund University.; Lunds universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; C3a; LL-37; antimicrobial peptide; GRAB; alpha-2-macroglobulin; proteolysis; SpeB; internalization; virulence; protein F1; Streptococcus pyogenes; fibronectin;

    Abstract : The bacterial surface can be thought of as the interface where pathogenic bacteria encounter the human host. Interactions between bacterial surface proteins and human proteins are important determinants of the eventual outcome of infection. READ MORE

  3. 3. Plasminogen and protein PAM: Interactions between streptococcal surface proteins and the human fibrinolytic system

    University dissertation from Department of Microbiology, Kalmar County Hospital, 391 85 Kalmar, Sweden

    Author : Annika Carlsson Wistedt; Lund University.; Lunds universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; M protein; streptokinase; kringles; plasmin; Streptococcus pyogenes; plasminogen; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Pathogenic bacteria often produce potent proteases capable of destroying host tissue thereby providing the bacteria with tools for spreading and nutrient access. This thesis describes how group A, C and G streptococci can acquire surface bound protease activity through an alternative mechanism, namely by binding and activation of the human protease precursor plasminogen.

  4. 4. Bacterial modulation of host glycosylation - in infection, biotechnology, and therapy

    University dissertation from Division of Infection Medicine

    Author : Jonathan Sjögren; Lund University.; Lunds universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; endoglycosidase; Streptococcus pyogenes; glycosylation; EndoS;

    Abstract : A majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. READ MORE

  5. 5. Immunoglobulin-binding bacterial surface proteins; biomedical tools and virulence factors

    University dissertation from Lund University, Dept. of Cell and Molecular Biology, P.O. Box 94, S-221 00 Lund, Sweden

    Author : Britt-Marie Kihlberg; Lund University.; Lunds universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; M-like protein; M protein; Protein L; Protein G; Ig-binding; Streptococcus pyogenes; Fc Receptors; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Cysteine proteinase; Streptolysin;

    Abstract : Many bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. READ MORE
