Hierarchical cluster analysis of PFGE Xba I patterns of 10,198 (10,193+5) Salmonella isolates. The dendrogram shows a simplified tree-structure of 10,198 isolates of five serotypes: S. I 4, [5],12:i:- (4,5), S. Hadar (H), S. Oranienburg (O), S. Thompson (T), and S. Typhi (Ty). Five of 10,198 isolates are test isolates and labeled as T1 to T5 in various colors, while the rest of the isolates are retrieved from the PFGE database bound with the tools. The number in parentheses indicates the number of isolates in the branch squares. There are nine major clusters (C1 to C9) and 17 sub-clusters (c1 to c17) grouped by the hierarchical cluster analysis tool.
