1. 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
2. Group A Streptococci; Epidemiology and Genetics of Antibiotic Resistance
Sammanfattning : Group A streptococci (GAS) cause throat and skin infections, severe invasive diseases as well as the non-suppurative complications acute rheumatic fever and glomerulonephritis. GAS have retained susceptibility to betalactam drugs, but resistance to alternative antibiotics is of concern. LÄS MER
3. Streptococcal cell surface proteins : structure and gene characterisation
Sammanfattning : Streptococcus pyogenes (group A streptococci, GAS) is a potent human pathogen known to express a number of cell surface associated virulence factors. It is an established fact that these different surface proteins play an important role during infection. LÄS MER
4. Clinical and molecular studies of β-haemolytic streptococci
Sammanfattning : Beta-haemolytic streptococci (BHS) are important causes of human infections and they have traditionally been grouped according to Lancefield antigens. The spectrum of infections caused by BHS includes pharyngitis, skin infections, bacteraemia/sepsis, endocarditis, septic arthritis and meningitis. LÄS MER
5. Invasive group A streptococcal infection : host and pathogen interactions
Sammanfattning : Invasive group A streptococcal (GAS) infections were studied in 229 patients with a clinical diagnosis of erysipelas and 151 patients with GAS bacteremia, respectively. Beta-hemolytic streptococci were identified in about a third of the erysipelas patients, mostly group A, whereas group G streptococci were identified in about half as many episodes. LÄS MER
