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

23 Escherichia coli O26 isolates were recovered from 250 samples collected over a year-long pilot study on a dairy farm in England. The dataset includes genomic characterization of isolates for serotype, sequence type, virulence genes, and SNP analysis. Alannah S. Deeney published the data on figshare in April 2026.

Use Cases

• Modeling pathogen persistence in livestock herds based on temporal and environmental sampling.
• Analyzing genomic relatedness between farm and human isolates based on SNP analysis.
• Investigating associations between STEC detection and environmental predictors using Bayesian logistic regression results.
• Tracking virulence gene profiles (stx1a, stx2a, eae) within a specific cattle reservoir.

Strengths

• Includes 250 samples collected across four visits, providing temporal and environmental variation.
• Contains genomic data for 20 sequenced isolates, with confirmed serotype (O26:H11) and sequence types (ST21, ST29).
• Results from a Bayesian logistic regression model evaluating predictors of STEC presence are included.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The dataset is small (75.0 KB), representing a single farm study with ~200 cattle, limiting generalizability.
• Description metadata is limited; actual data quality requires manual inspection after download.
