Description
Shamsul Qumar and co-authors present a 2026 global genomic analysis of Campylobacter jejuni, a leading cause of bacterial food poisoning for which poultry is a major reservoir. Heavy antibiotic use in livestock has bred multidrug-resistant strains, so the team compared genomes from human and chicken hosts in a One Health frame linking animal and human risk.
The analysis covered 1,125 high-quality genomes, including five newly sequenced chicken isolates, and sorted their genes into 4,489 clusters with a conserved core of 1,360. Family trees split into three big clades with little regard for geography; human strains appeared everywhere, while chicken strains concentrated in one clade, hinting at host adaptation. All five new isolates resisted several drugs. Across the set, 31 known resistance genes turned up, underlining the scale of the resistance problem.
