The distinct clustering of C. jejuni isolates from starlings. A. A Clonal Frame analysis demonstrating that the majority of C. jejuni isolates from starlings cluster separately from C. jejuni isolates representative of the diversity isolated from human disease and farm animals. Clusters that can be related to clonal complexes are indicated. B. The probabilistic assignment of the same C. jejuni allelic profiles to host source using Structure. Each allelic profile is represented by a vertical bar, showing the estimated probability that it comes from each of the sources identified. Key: starling (red), ruminant (green), environment (blue), human disease (yellow), poultry (pink).
