Minimum spanning tree built using the Bionumerics sofware on ST41-Mirutyped DNAs (Version 3.5, Applied Maths, Sint-Marteen-Latem, Belgium). 3A : tree panel window. 3B: complex panel window showing the MIRU value of the presumed origin of the tree. Genotypes are arbitrarily designated by letters. B : 215125113322 is suggested as the original genotype. For each designation, the number of cases is indicated (ex: 22 cases for genotype B). The number on the branch indicates the change required to go from one allele to another : exemple: a change on the 3rd MIRU on genotype B from an allelic value = 5 to a value = 4 provides genotype F.
