Salmonella Cerro Genomes from a Wisconsin Dairy Farm, 2022-2023

University of Wisconsin-Madison researchers sequenced 32 Salmonella enterica serotype Cerro isolates from healthy lactating dairy cattle on a single Wisconsin farm. The isolates were collected via direct fecal sampling over a one-year period between March 2022 and February 2023. Whole genome sequencing was performed using paired-end short-read Illumina sequencing to assess genomic stability.

Use Cases

• Assessing genomic stability of a bacterial serovar over time based on the one-year sampling period
• Characterizing the Salmonella Cerro genome specific to a dairy farm environment
• Comparative genomics of Salmonella isolates from healthy livestock based on the described source
• Studying pathogen population dynamics within a closed agricultural system based on the single-farm sampling

Strengths

• 32 sequenced isolates provide a defined sample size for analysis
• Data covers a one-year temporal series from March 2022 to February 2023
• All isolates originate from a single farm, allowing for controlled environmental study

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the single Wisconsin farm source
