Figure 2. Minimum Spanning Tree (MST) analysis of B. abortus isolates using the MLVA16 data.

Figure 2

The minimum spanning tree presented is the one with the highest overall reliability score and was calculated using UPGMA associated with the priority rule and the bootstrap resampling for strains of Brucella abortus isolated from cattle in Brazil, 1977 to 2008, the reference strains for each biovar of B. abortus and the vaccine strains S19 and RB51. Numbers in each clonal complex represent the genotype on Panel 1. Information on the origin of the isolates was color labeled.
