Figure 2

Minimum spanning tree of 79 Salmonella Enteritidis isolates. (a) Each node represents a unique MLVA profile, indicated by the number in the middle of the circle. The nodal size is proportional to the number of isolates per MLVA profile. The colour within each node reflects the proportion of strains isolated from different periods per node. The length of the branches represents genetic distance (change in loci) between two neighbours. Bold short lines connect two MLVA types differing by a single MLVA locus. Thin longer lines connect double or triple variants, and dotted lines indicate connection between two types differing by four MLVA loci. Clonal complexes were created based on maximum neighbour distance changes at two loci. (b) This is the same minimum spanning tree as in Figure 1a. Wedges in circles indicate the proportion of isolates from respective sources with a particular MLVA profile.
