1. 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
2. TRANSMISSION AND PATHOGENESIS OF HANTAVIRUS
Sammanfattning : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. LÄS MER
3. Studies on human secretory immunoglobulins : gross conformation of secretory IgA and binding of secretory components to immunoglobulins A and M
Sammanfattning : .... LÄS MER
4. 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
5. Temporary neonatal exposure to whole and hydrolysed cow's milk proteins. Studies of macromolecular absorption and immunological variables
Sammanfattning : The aim of this work was to study prospectively the effects of different feeding regimens during the first three days of life. A group of 129 infants were randomly assigned at birth to one of three feeding regimens: human milk (HM), cow's milk formula (CMF), or a casein hydrolysate formula (CHF). LÄS MER
