Figure 5. Distribution of large cluster isolates of Campylobacter jejuni from Denmark, over time. The 22 large genetic clusters (>5 clinical isolates) are listed vertically, and the cluster isolates are displayed over time (in days) horizontally. Each cluster is centered at the median date of the cluster isolates (t = 0). Each dot represents an isolate at a certain time, and colors indicate the origin of the isolate. The 6 clusters ST257#6, ST48#5, ST50#9, ST257#4, ST5#1, and ST51#1+ST21#2 are also illustrated in Figure 3. (a) indicates the 2 clusters representing the multistrain outbreak from the fifth CML; (b) indicates the 2 clusters linked by the same patient having an isolate part of each cluster.
