The paper characterizes six chimeric plasmids from Salmonella Heidelberg, revealing multidrug resistance and increased pathogenicity through genetic and functional analysis.

The paper constructs genome-scale metabolic models for APEC phylogroups B2, C, and G, identifying a lineage-specific metabolic pathway in phylogroup C that distinguishes it from other groups.

This study compares phenotypic differences among high-risk APEC clonal groups in vitro and in vivo, finding variation in invasion, survival, and virulence.

This study analyzes global S. pseudintermedius genomes to identify genomic and prophage diversity in multidrug-resistant lineages, showing prophage integration and antiviral systems correlate with disease success.

This study identifies host-specific genetic determinants in E. coli using genome-wide association, revealing lineage-specific adaptations to human, cattle, chicken, and pig hosts.

The paper uses shotgun metagenomics to analyze equine fecal samples, revealing taxonomic and functional diversity in the horse gut microbiome, including novel bacterial genera and species.
