STEC O26 Genomic Data from a UK Dairy Farm Over One Year

250 samples were collected from a dairy farm in England over four visits, yielding 23 E. coli O26 isolates. Alannah S. Deeney published this genomic study on figshare in April 2026, detailing the persistence and phylogenetic analysis of Shiga toxin-producing Escherichia coli (STEC) O26. The data includes results from whole-genome sequencing, SNP analysis, and Bayesian logistic regression modeling.

Use Cases

• Model pathogen persistence in livestock herds based on temporal and environmental sampling data
• Analyze genomic relatedness between farm and human isolates based on SNP analysis results
• Predict STEC detection odds based on housing conditions using Bayesian logistic regression model outputs
• Characterize virulence gene profiles based on whole-genome sequencing data for stx subtyping and pathogenicity islands

Strengths

• 250 samples collected across four visits provide a temporal snapshot
• 20 isolates successfully sequenced with confirmed serotype and sequence types
• Analysis includes SNP comparison showing at least 51 SNP differences from human isolates

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
