The paper reports an increase in USA300-SAE MRSA in Chile, links its spread to environmental copper resistance, and suggests copper exposure may enhance its fitness.

This study shows that fumarate, regulated by host and pathogen, limits S. aureus growth by blocking metabolic pathways, while FumC enables adaptation through fumarate degradation and utilization.

This study investigates the prevalence and role of Staphylococcus aureus superantigens in CF lung disease, showing their ability to induce inflammatory responses in mouse models.

This study identifies transcriptional and post-transcriptional regulators of RydC, an sRNA that modulates cyclopropane fatty acid synthase in E. coli, revealing a network linking membrane stress responses to environmental signals.

The paper shows that small RNAs in E. coli regulate gene expression by modulating Rho-dependent transcription termination in the cfa mRNA 5' UTR.

The paper reconstructs the pre-epidemic evolution of the USA300 MRSA lineage using genomic data and identifies a third major clade and molecular markers for classification.

The paper reports and compares B.1.1.7+E484K SARS-CoV-2 isolates from Pennsylvania, identifying 7 clonal complexes and 3 distinct clades in the US.
