Group A Streptococcus strains causing meningitis without distinct invasive phenotype

This study compares GAS strains from meningitis and otitis cases, finding no distinct invasive traits associated with meningitis.

Group A Streptococcus antibiotic tolerance in necrotizing fasciitis

This study shows that Group A Streptococcus (GAS) persisters are present in tissue from necrotizing fasciitis patients and contribute to antibiotic treatment failure.

Limited adaptive evolution of Staphylococcus aureus during transition from colonization to invasive infection

The paper compares phenotypic and genotypic profiles of S. aureus colonizing and invasive isolates, finding limited genetic evolution and similar traits, with barrier disruption as key to disease progression.

Quantification of within patient Staphylococcus aureus phenotypic heterogeneity as a proxy for presence of persisters across clinical presentations

This study quantifies phenotypic heterogeneity in Staphylococcus aureus from patient samples to assess persisters, finding that rifampicin treatment correlates with increased growth delays.

Genomic surveillance of vancomycin-resistant Enterococcus faecium reveals spread of a linear plasmid conferring a nutrient utilization advantage

This study identifies a linear plasmid in vancomycin-resistant Enterococcus faecium that confers a nutrient utilization advantage, contributing to its spread in a hospital setting.
