1. Streptococcus pneumoniae : epidemiological, clinical and serological studies
Sammanfattning : A retrospective study of invasive pneumococcal disease in patients from Greater Göteborg in 1964- 1980 identified 125 cases of meningitis, 305 of pneumonia, 61 of septicemia with unknown focus, and 17 with other manifestations, all verified by cultures from normally sterile body fluids. The incidence was several times higher in infants and in the elderly than in any other age-group. LÄS MER
2. Superantigens in group A streptococcus : gene diversity and humoral immune response
Sammanfattning : Group A streptococcus (GAS) is a strictly human pathogen that causes infections ranging from asymptomatic carriage to the highly lethal streptococcal toxic shock syndrome (STSS). GAS are classified according to the sequence of the variable 5’ end of the emm-gene that encodes the surface associated M-protein. LÄS MER
3. Quantifying Phagocytosis – studies on the antibody response during invasive streptococcal infections
Sammanfattning : The interaction between our immune system and pathogens encompasses a complex spectrum from symbiosis to potentially life-threatening diseases. Throughout evolution, our immune system has evolved numerous strategies such as phagocytosis to combat infections and protect us from diseases. LÄS MER
4. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria
Sammanfattning : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. LÄS MER
5. Antibiotic resistance and pathogenesis of Streptococci with focus on Group A Streptococci
Sammanfattning : Multi-drug resistant (MDR) infections remain the leading cause of death worldwide. MDR infections caused by Streptococcus pneumoniae (Spn), Streptococcus pyogenes (GAS) and Streptococcus agalactiae (GBS) are considered global threats to human health due to increased spread of antibiotic resistance and limited treatment options.
