2. 1. Mechanisms of phagocytosis resistance in Streptococcus pyogenes

   Author : Heike Kotarsky; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; fibrinogen; FHL-1; Factor H; M protein; Streptococcus pyogenes; phagocytosis;

   Abstract : A distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and fibrinogen that plays a key role in coagulation.

4. 2. Polyomavirus infections in humans

   Author : Annika Lundstig; Malmö Klinisk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Polyomaviruses; tumour virology; BK virus; neuroblastoma; maternal infection; Real Time PCR; enzyme immunoassay; seroprevalence; JC virus; SV40; virus like particles VLPs ; seroepidemiology; biobank; mesothelioma tissues; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : The human polyomaviruses BKV and JCV are endemic and infect > 70% of population worldwide. Primary infections occur during childhood and are largely subclinical. Following primary infection, both viruses persist as latent infections in the kidneys and B lymphocytes. READ MORE

5. 3. Role of TLR4 in Escherichia coli urinary tract infection

   Author : Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

   Abstract : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. READ MORE

6. 4. Role of Neutrophils and Innate Immune Mechanisms in Urinary Tract Infections

   Author : Björn Frendéus; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Mucosal immunology; Infection Resistance; Neutrophils; Toll-like receptors; Urinary Tract Infections; Chemokine receptors; bakteriologi; virologi; mykologi;

   Abstract : Urinary tract infections (UTI) are among the most common infections in man. Despite their prevalence, information on the molecular mechanisms defects that explain the increased susceptibility to disease are lacking. READ MORE

7. 5. Ehrlichia in animals and humans

   Author : Anneli Bjöersdorff; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; seroprevalence; humans; animals; granulocytic; ehrlichiosis; Ehrlichia phagocytophila; tick-borne; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : Ehrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death.
