Figure 3

Cluster-graph drawn from spoligotyping data of 344 TB cases censused in French Guiana over the 1996–2003 period. Each node represents a genotype, and arrows point in the direction of genotypes possibly derived by deletion in the marker locus. Vertex (or node) size indicates the size of the cluster. Twenty nine non-censused spoligotypes, which are hypothetical intermediates or ancestors of censused spoligotypes, were added and schematised as a point (e.g. STs 119 and 236, putative ancestors of X clade and EAI clade, respectively).
