The study shows that fitness costs of antibiotic resistance mutations in rich media do not reliably predict their costs in infection-like environments, with increased costs in lung-mimicking media and reduced prevalence in urinary tract-mimicking media.

This paper examines whether viromes can serve as signatures of microbiome health by analyzing published studies on phage and bacterial diversity in healthy and dysbiotic states.

The paper compares the fitness effects of chromosomal and plasmid genes in Rhizobium leguminosarum, finding that plasmids are depleted in beneficial genes, especially ancient ones, suggesting evolutionary pressure drives beneficial genes to the chromosome.

This study examines how Pseudomonas aeruginosa adapts to repeated invasion of Staphylococcus epidermidis, showing divergent evolutionary responses between monoculture and coculture conditions.

A uniformly processed set of 2,440,377 bacterial and archaeal genomes with search tools and annotations, plus an AI-mined peptide set yielding ATB20, active in a mouse skin infection model.

This study shows CRISPR-Cas systems in Pseudomonas aeruginosa limit horizontal gene transfer by targeting phage and conjugative elements, leading to smaller genomes and reduced GC content.
