Partial dendrogram MLVA-16 clustering analysis of 170 Brucella isolates, with all 93 of the B. melitensis and 29 B. abortus isolates included in this study. The columns present the following data: original strain number [Strain id.], MLVA cluster number reference [Ref. cluster], epidemiologic relatedness (a-d indicate isolates from the same patient, 1-3 indicate isolates that are epidemiologically linked to each other)[Linked], highest logarithmic value of the four generated MS spectra [High LogValue], number of the 4 generated MS spectra corresponding with species identification using MLVA [N identified], genus [Genus], species [Species], and biovar [Biovar] identification based on the MLVA database. The similarity axis is presented in the top left corner. Each color reflects a different cluster with > 52.5% similarity. The group of 'melitensis-abortus' isolates clustered as follows: B. melitensis isolates grouped in Clusters 1, 2, and 3. B. abortus isolates grouped in Clusters 4, 6, and 7. Outlier B. abortus/melitensis W99 is a singleton (Cluster 5).
