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

7. Studies of immune responses to cell surface proteins of Helicobacter pylori and Borrelia burgdorferi by enzyme immunoassay and immunoblotting
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
8. Surface proteins of pathogenic streptococci
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
9. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract
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
10. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators
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
