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

23 Escherichia coli O26 isolates were recovered from 250 samples collected during a year-long pilot study on a dairy farm in England. The dataset includes genomic characterization data for a subset of 20 isolates, including serotype, sequence type, virulence genes, and SNP analysis. The data was published by Alannah S. Deeney on figshare in April 2026.

Use Cases

• Analyzing pathogen persistence within a herd based on SNP analysis results
• Modeling associations between STEC detection and environmental predictors using Bayesian logistic regression
• Comparing farm isolates with human clinical isolates based on genomic relatedness
• Studying temporal variation in pathogen detection across four sampling visits

Strengths

• Includes genomic data for 20 isolates with confirmed serotype and sequence types
• Based on 250 samples collected across four visits over a year
• Provides specific SNP distance metrics (at least 51 SNPs) for comparing isolates

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data is from a single farm (~200 cattle), limiting generalizability
