1. 16. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes

   Författare :Karin Berggård; Lund Dermatologi och venereologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; antigenic variation; phagocytosis resistance; complement; C4b-binding protein C4BP ; Bordetella pertussis; Streptococcus pyogenes; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Many microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. LÄS MER

3. 17. 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.

4. 18. Severe Streptococcus pyogenes disease in Europe; epidemiology and clinical manifestations

   Författare :Bogdan Luca; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; streptococcal toxic shock syndrome; necrotising fasciitis; emm-type; invasive GAS disease; superantigen;

   Sammanfattning : Streptococcus pyogenes, gives rise from mild skin infections and pharyngitis, to life threatening infections like bacteraemia, cellulitis, puerperal sepsis, meningitis, pneumonia, necrotizing fasciitis (NF), and streptococcal toxic-like shock syndrome (STSS), or nonsuppurative sequelae, rheumatic fever and glomerulonephritis. In 2002, the first multinational network for invasive GAS disease surveillance was initiated by the EU-funded Strep-EURO project. LÄS MER

5. 19. Clinical and molecular studies of β-haemolytic streptococci

   Författare :Kristina Trell; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Beta-hemolytic streptococci; Streptococcus dysgalactiae; MALDI-TOF MS analysis; Streptococcus equi; Streptococcus pyogenes; endometritis; Erysipelas;

   Sammanfattning : Beta-haemolytic streptococci (BHS) are important causes of human infections and they have traditionally been grouped according to Lancefield antigens. The spectrum of infections caused by BHS includes pharyngitis, skin infections, bacteraemia/sepsis, endocarditis, septic arthritis and meningitis. LÄS MER

7. 20. Molecular analysis of Streptococcus pyogenes and its interactions with the human host

   Författare :Andreas Berge; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement activation; fibrinogen; IgG; M protein; C5a peptidase; streptococcal cysteine proteinase; streptokinase; t-PA; Streptococcus pyogenes; plasminogen; C1q; insertional sequence.; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Streptococcus pyogenes causes infections only in humans, from trivial tonsillitis to life-threatening conditions. One of its most important virulence factors is the M-like protein family conferring resistance to phagocytosis to the bacterium. The M-like proteins are surface exposed rod-like molecules attached to the cell wall. Each strain of S. LÄS MER
