Staphylococcus pettenkoferi: an underrecognized species with clinically relevant antimicrobial resistance. A comprehensive genomic European study

ABSTRACT Staphylococcus pettenkoferi has increasingly been reported as a human pathogen, with virulence potential recently confirmed in vivo. However, its genomic diversity and antimicrobial resistance remain insufficiently characterized. This study, conducted within the PETTENK-OS project of the ESCMID Study Group for...

Training a phage to expand its host range: directed evolution against Staphylococcus aureus from diabetic foot infections

Both the potential and the limitations of phage training to expand therapeutic coverage are demonstrated and the need to integrate evolutionary approaches with physiologically relevant models to optimize phage therapy for chronic infections, such as DFIs is emphasized.

Circulating blood microbiome biomarkers as liquid biopsy in breast cancer

The findings support liquid microbiopsy as a complementary extension of liquid biopsy but must be considered as exploratory, and warrant multicenter validation in larger independent cohorts with standardized pre-analytics and low-biomass controls.

A secreted AIP-Like peptide from Helcococcus kunzii inhibits the Agr quorum sensing system of Staphylococcus aureus

It is demonstrated that Adh2 suppresses Agr signaling and virulence gene expression while promoting a persistent phenotype, and emerges as a promising candidate for therapeutic modulation of bacterial behavior, particularly in the context of chronic wound infections.
