1. 6. Genetic and serologic characterization of a Swedish human hantavirus isolate

   Författare :Marie Lindkvist; Göran Bucht; Clas Alhm; Per Juto; Rainer Ulrich; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hantavirus; puumalavirus; diagnostics; HFRS; nucleocapsid protein; B-cell epitopes; epitope-mapping; protein interactions; glycosylation; antibody response; cross-reactivity; Virology; Virologi;

   Sammanfattning : Hantaviruses are found practically all over the world and cause hemorrhagic fevers in man. Each year about 150,000 people are hospitalized in these zoonotic infections which can be of two types: hemorrhagic fever with renal syndrome (HFRS) or hantavirus cardiopulmonary syndrome (HCPS), depending on the infecting virus.

3. 7. Studies of immune responses to cell surface proteins of Helicobacter pylori and Borrelia burgdorferi by enzyme immunoassay and immunoblotting

   Författare :Ingrid Nilsson; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; B. burgdorferi; H.pylori; cell surface proteins; gel-electrophoresis; enzyme immunoassay; Western immunoblotting; bacteriology; Microbiology; bakteriologi; virologi; mykologi;

   Sammanfattning : Helicobacter pylori and Borrelia burgdorferi s.l. can cause chronic infections by evading the immune system. These two human pathogens express a number of immunogenic cell surface proteins. LÄS MER

4. 8. Surface proteins of pathogenic streptococci

   Författare :Thomas Areschoug; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 9. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

   Författare :Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

   Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER

7. 10. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

   Författare :Eskil Johnsson; Institutionen för laboratoriemedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

   Sammanfattning : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. LÄS MER
