Figure 1From: Multilocus variable-number tandem repeat analysis for molecular typing and phylogenetic analysis of Shigella flexneriDendrogram for Shigella flexneri isolates. The dendrogram is constructed using PFGE patterns for 242 Shigella flexneri isolates. Clusters are designated on the basis of the level of genetic relatedness and serotypes. Isolates in each of the three subclusters of cluster C4 shared at least 80% pattern similarity.Back to article page
