1. Streptococcal immunoglobulin degrading enzymes of the IdeS and IgdE family
Sammanfattning : Bacteria of the genus Streptococcus are common asymptomatic colonisers of humans and animals. As opportunistic pathogens they can however, depending on their host’s immune status and other circumstances, cause mild to very severe infections. LÄS MER
2. Endemic and epidemic Streptococcus pyogenes strains : reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis
Sammanfattning : The bacterium Streptococcus pyogenes is a common human pathogen known to cause bothuncomplicated and severe infections. Epidemics of invasive disease caused by S. pyogenesserotype T1 were seen in the county of Uppsala, Sweden, in 19881989 and 1994. LÄS MER
3. Streptococcus pyogenes - a manipulator of human defences
Sammanfattning : Streptococcus pyogenes is a major human pathogen with more than 500 000 casualties annually of which at least 163 000 are due to invasive infections. The remainder is due to post-streptococcal complications with rheu¬matic heart disease constituting the majority. S. LÄS MER
4. Multifaceted RNA-mediated regulatory mechanisms in Streptococcus pyogenes
Sammanfattning : Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. LÄS MER
5. Post-transcriptional regulation by RNases in Streptococcus pyogenes
Sammanfattning : Ribonucleases (RNases) are proteins that adjust cellular RNA levels by processing RNA transcripts, leading to their stabilization or degradation. RNases are grouped based on their ability to cleave the transcript internally (endoRNases) or degrade the transcript starting from the ends (exoRNases). LÄS MER
