Genotype Cluster Analysis in Pathogenic Escherichia coli Isolates Producing Different CDT Types

Figure 1

Dendrogram using average linkage between groups: This figure illustrates hierarchical clustering analyses between 30 examined clinical isolates which are clustered based on virulence-associated factors including virulent plasmid, phage, chromosomal, and pathogenicity island genes. At the end of each branch the numbers indicate strains, as moving to the right relative distance becomes more apparent. Distances are more distinct by using a 0 to 25 scale along the top of the chart. Depicted table which is in front of the tree illustrates the comparative patterns of cooccurrence and presence of virulent genes in different strains (light gray scale shows gene loss and different dark gray scales show different virulent genes genesis). Defined pattern can be observed for each cdt-type isolates based on other virulent genes.
