design: Whole genome sequencing (WGS) was performed on 82 Campylobacter isolates collected across three sampling days. Approximately six isolates were selected per sample type (NS, NS-M, BF, BF-M) to investigate genomic diversity and potential presence of multiple sequence types (STs) in the same sample. DNA was extracted using the DNeasy Blood & Tissue Kit (Qiagen, Germany) following the manufacturer's protocol. Sequencing libraries were prepared with Illumina standard paired-end protocols and sequenced on an Illumina NovaSeq 6000 platform, generating 150 bp paired-end reads.
