SNVs in Salmonella Genomic Recombining Regions RR2 and RR3

Illumina sequencing reads from 152 Salmonella isolates, including 140 S. Napoli, 10 S. Veneziana, and 2 S. Mississippi. The data reports single-nucleotide variants across two specific chromosomal regions (RR2 and RR3) mapped to a reference genome. The dataset was authored by Lise Frezal and last updated on 2026-05-06.

Use Cases

• Identify genetic variation patterns within Salmonella populations based on single-nucleotide variant data.
• Compare genomic diversity across different serovars (Napoli, Veneziana, Mississippi) based on the isolate counts.
• Analyze recombination dynamics in specific chromosomal regions (RR2 and RR3) based on the focal genomic coordinates.

Strengths

• Data is derived from 152 sequenced bacterial isolates, providing a population-level view.
• Focuses on two defined genomic regions (RR2 and RR3) with precise chromosomal coordinates.
• Uses a specific reference genome (S. Napoli strain Nap72-2, GenBank CP163475) for mapping consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific isolates and sequencing platform used.
