"SCHOOL CUTS 'MIXING' AFTER BUG OUTBREAK"
@zachharrison.bsky.social for @boltonnews.bsky.social

A #PrimarySchool in #Bolton, #GreaterManchester has introduced class bubbles and cancelled events following cases of #GroupA #Streptococcus among their pupils.

The study shows that even when certain #Streptococcus #pneumoniae mutants are attenuated for invasive disease, they can invade the mucosal epithelium and trigger #innate immune responses. A really valuable contribution to our understanding of #host–pathogen interactions and pneumococcal biology

Dual activation of the cytoplasmic sensor ComR by XIP pheromone or aromatic amino acid catabolites in salivarius streptococci. Left: Classical activation of the ComRS system by XIP for intraspecies QS, leading to a coactivation of competence (DNA uptake) and predation (salvaricin production). Production of salivaricins takes place in a pulse mode due to a combined positive and negative feedback loop through ComS and the ComX-PepF relay (XIP degradation), respectively. Right: Pheromone-independent activation of ComR by aromatic amino acid catabolites for interspecies dysbiosis-sensing, leading only to the activation of predation. Production of salivaricins takes place in a continuous mode due to an absence of a negative feedback loop.

Structural basis for collagen recognition by the Streptococcus pyogenes M3 protein and its involvement in biofilm The T-shaped fold of an abundant surface protein ties streptococci to collagens, an interaction that enhances biofilm such as often found in invasive infections.

About time to post about our recent paper on the interaction of the group A #streptococcus #StrepA M3 protein with collagen. Took over a decade to get here. I always thought it mad to embark on structural work with collagens. Or M proteins, for that matter. elifesciences.org/articles/105...

Clinical characteristics of 159 episodes of Streptococcus dysgalactiae subsp. equisimilis bacteremia from November 2015 to November 2019 in Pirkanmaa Health District, Finland. Differences between specific emm type compared with all other episodes were tested using the Mann-Whitney U-test, Pearson χ² test (marked as *), or Fisher’s exact test. The numbers are bolded if P <0.05.

What is erysipelas?

Erysipelas is an acute inflammation of all layers of the skin caused by hemolytic streptococcus, which penetrates the skin through microtraumas. How does hemolytic streptococcus penetrate the skin during erysipelas?
