Rarefaction curve of Campylobacter jejuni clinical isolates from Denmark, 2015–2017. Curve of cluster types is shown relating to the left y-axis, revealing 512 different cluster types, which encompass the 104 defined clusters as well as the 408 sporadic cases assigned to their own cluster type. The right y-axis indicates the percentage of clinical isolates assigned to any cluster or a large cluster for a given subsample size. The rarefaction curve indicates that only a small fraction of the dive

The right y-axis indicates the percentage of clinical isolates assigned to any cluster or a large cluster for a given subsample size. The rarefaction curve indicates that only a small fraction of the diversity is sampled; a larger fraction of the sporadic isolates would be included in clusters if a greater fraction of the population had been sampled.
