Emergent Invasive Group A Streptococcus dysgalactiae subsp. equisimilis, United States, 2015–2018
Emerging Infectious Diseases, 2019 The term group A Streptococcus is considered synonymous for the species Streptococcus pyogenes. We describe an emergent invasive S. dysgalactiae subspecies equisimilis lineage that obtained the group A antigen through a single ancestral recombination ...

Extraction of the T Antigen of Streptococcus pyogenes [PDF]
Journal of General Microbiology, 1951 SUMMARY: The heat-stability of the T antigen of strains of Streptococcus pyogenes grown in Pope S with several strains 30 minutes' boiling was insufficient to eliminate all T agglutinability. By heating suspensions of streptococci to 80° for 30 min. and then treating the heated suspensions with trypsin-containing pancreatic extract for a few hours, T ...

CRISPR-Cas in Streptococcus pyogenes [PDF]
RNA Biology, 2019 The discovery and characterization of the prokaryotic CRISPR-Cas immune system has led to a revolution in genome editing and engineering technologies. Despite the fact that most applications emerged after the discovery of the type II-A CRISPR-Cas9 system of Streptococcus pyogenes, its biological importance in this organism has received little attention.

Genetic Manipulation of Mammalian Cells in Microphysiological Hydrogels
Advanced Science, EarlyView.Supply channels for cells embedded in gels can be used for in situ genetic manipulation. Abstract Engineering functional 3D tissue constructs is essential for developing advanced organ‐like systems, with applications ranging from fundamental biological research to drug testing. The generation of complex multicellular structures requires the integration

TIV vaccination modulates host responses to influenza virus infection that correlate with protection against bacterial superinfection [PDF]
, 2019 Background: Influenza virus infection predisposes to secondary bacterial pneumonia. Currently licensed influenza vaccines aim at the induction of neutralizing antibodies and are less effective if the induction of neutralizing antibodies is low and/or the

Binding of Streptococcus pyogenes to laminin.
Journal of Biological Chemistry, 1984 Some strains of Streptococcus pyogenes isolated from infected human tissues were shown to bind laminin, a major component of basement membranes. Binding of 125I-laminin to bacteria was time dependent and functionally irreversible. Of several unlabeled proteins tested in competition experiments, laminin and fibrinogen inhibited binding of the ...

Fulminant streptococcus pyogenes infection. [PDF]
BMJ, 1980 Life-threatening infection due to Streptococcus pyogenes (? haemolytic streptococcus, Lancefield's group A) has become uncommon since the introduction of penicillin.1 2 3 Excluding the four cases reported here, the department of bacteriology at this hospital has seen only six cases of Str pyogenes bacteraemia in the past 10 years, and nationally the ...

Advanced Science, EarlyView.This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.
