Minimum spanning trees obtained using 11 markers for the polymorphism profile of 206 Salmonella enterica subspecies strains discriminated into 107 MLVA types. The MST construction was made using the categorical coefficient. Each circle represents a different MLVA type. Each serovar is shaded with a different color. The size of the circle reflects the number of isolates whereas the distance between the circles represents the genetic divergence (heavy short lines connect SLVs, thin long lines connect DLVs, and dotted lines indicate the connection between 2 allelic distribution types). The number in each circle indicates the genotype. Red dotted squares indicate human isolates. The halos surrounding the various types denote the groupings obtained by Bionumerics analysis. In Bionumerics MLVA clonal complexes are grouping genotypes different by one allele.
