2. 11. Surface proteins of pathogenic streptococci

   Author : Thomas Areschoug; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; virology; 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

4. 12. Pathogenesis of infections related to foreign devices within the cerebral ventricles

   Author : Fredrik Lundberg; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; CSF-shunt; complement activation; vitronectin; hydrocephalus; coagulase-negative staphylococci; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : Coagulase-negative staphyloccoci (CoNS) are the most frequently isolated micro-organisms from infected cerebrospinal fluid (CSF) shunts and temporary ventricular drainage catheters, used in modern neurosurgery. CoNS originate from the skinflora of the patient or the surgeon and gain access to the surface of the implant at the insertion, but the infection can erupt up to a year later or more. READ MORE

5. 13. Human Endogenous Retroviruses: Expression and Evolutionary Relationships

   Author : Marie-Louise Andersson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; Microbiology; bakteriologi; expression; transcription; reverse transcriptase; HERV; phylogeny; virologi; mykologi;

   Abstract : The human genome contains genetic elements which are more or less similar to infectious retroviruses. These are called human endogenous retroviruses (HERVs) and are thought to be remnants of infections in the primate lineage. READ MORE

6. 14. 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.

7. 15. Influence of FK506 on certain aspects of lymphocyte activation and lymphocyte-endothelial cell interactions in vitro

   Author : Håkan Karlsson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytokine; adhesion molecule; endothelium; lymphocyte metabolism; interleukin 2 receptor; FK506; cyclosporin A; Mikrobiologi; bakteriologi; virologi; mykologi; Immunology; transplantation; serology; Microbiology; bacteriology; mycology; virology; Immunologi; serologi;

   Abstract : In the present thesis, the influence of the immunosuppressive drug FK506 on mitogen-induced changes in the expression of subunits a and ß of the IL-2 receptor by isolated human peripheral blood mononuclear cells has been studied. Up-regulation and release of the a-chain were potently depressed by FK506, even in the presence of exogenous IL-2. READ MORE
