  1. 1. Antibiotic resistance and pathogenesis of Streptococci with focus on Group A Streptococci

    Författare :Feiruz Alamiri; Malmö Experimentell infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotika resistens; Bröstmjölk; Luftvägsinfektioner; Biofilm bildning; Internalisering; Persistens; HAMLET; Streptokocker; kolonisering; Streptococcus pneumoniae; biofilm formation; Internalisation; Persistence; Antibiotic resistance; Streptococcus pyogenes; Streptococcus agalactiae; HAMLET; Breast milk; Proteome; Virulence factors; Colonization;

    Sammanfattning : Multi-drug resistant (MDR) infections remain the leading cause of death worldwide. MDR infections caused by Streptococcus pneumoniae (Spn), Streptococcus pyogenes (GAS) and Streptococcus agalactiae (GBS) are considered global threats to human health due to increased spread of antibiotic resistance and limited treatment options.

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

    Författare :Marie Louise Wallengren; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunoglobulin A; Streptococcus mutans; Streptokocker; Karies;

    Sammanfattning : Mutansstreptokocker (MS) är en grupp bakterier som i många studier visats ha ett starkt samband med karies. Bakterierna anses tillhöra vår normala munflora, men alla individer har inte MS och mängden skiljer sig mycket från en individ till en annan. Orsakerna till denna variation är till viss del välkända, som t.ex. LÄS MER

  4. 3. Pathogen-host interactions at the surface of Streptococcus pyogenes

    Författare :Patrik Nyberg; Infektionsmedicin; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Annika Carlsson Wistedt; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :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;

    Sammanfattning : 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.

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

    Författare :Jonathan Sjögren; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; endoglycosidase; Streptococcus pyogenes; glycosylation; EndoS;

    Sammanfattning : 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. LÄS MER
