Understanding species-specific differences in virulence-associated features, antimicrobial resistance genes, and population structure is essential for assessing public health risks and guiding surveillance strategies.

The\n                    <jats:italic toggle=\"yes\">hcp<\/jats:italic>\n                    gene was detected exclusively in\n                    <jats:italic toggle=\"yes\">C. jejuni<\/jats:italic>\n                    isolates, indicating that it was detected only in\n                    <jats:italic toggle=\"yes\">C. jejuni<\/jats:italic>\n                    within this collection of the primary T6SS component. Both species shared a broad set of core virulence genes related to motility, colonization, quorum sensing, adhesion, and surface polysaccharide biosynthesis, while notable differences were observed in accessory virulence gene profiles. Genes associated with antibiotic resistance, including the tetracycline resistance gene\n                    <jats:italic toggle=\"yes\">tet<\/jats:italic>\n                    (O) and multiple efflux-related determinants, were frequently detected in both species. MLST analysis revealed high genetic diversity, with most isolates not assignable to previously defined sequence types, consistent with an open pan-genome and substantial genomic plasticity.
