Salmonella Montevideo Genomic and Epidemiologic Evidence for Attenuated Virulence

Ruixi Chen published this dataset on figshare in 2026. It contains genomic and epidemiologic evidence for attenuated virulence in Salmonella Montevideo associated with cattle and beef products in the United States. The data supports a phylogenetic analysis of 12 clades with distinct ecological associations.

Use Cases

• Comparative genomic analysis based on identified human-associated and non-human-associated clades.
• Evolutionary rate reconstruction based on described clade emergence timelines and stability.
• Virulence factor analysis based on enrichment of premature stop codons in specific genes.
• Risk modeling for food safety based on the link between cattle adaptation and reduced human virulence.

Strengths

• Dataset is licensed under CC-BY-4.0, permitting broad reuse.
• Description provides specific genomic findings, such as a 7–19-fold enrichment in premature stop codons in the non-human-associated clade.
• Phylogenetic framework is detailed, describing 12 clades with distinct ecological associations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 969.4 KB file size indicates a relatively small dataset with limited scope.
