Emergent Invasive Group A Streptococcus dysgalactiae subsp. equisimilis, United States, 2015–2018
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 ...

Erythromycin-resistant Streptococcus pyogenes
Streptococcus pyogenes is the most prevalent cause of tonsillopharyngitis in children. The drug of choice for infections caused by this microorganism is penicillin. The problem of treating such infections arises when erythromycin-resistant strains occur.

Restoration of human tooth enamel
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Pneumococcus and the stress-gradient hypothesis: a trade-off links $R_0$ and susceptibility to co-colonization across countries [PDF]
Modern molecular technologies have revolutionized our understanding of bacterial epidemiology, but reported data across different settings remain under-integrated in common theoretical frameworks. Pneumococcus serotype co-colonization, caused by the polymorphic bacteria Streptococcus pneumoniae, has been increasingly investigated in recent years. While
