Maximum parsimony analysis on 117 marine mammal Brucella genotypes. Each coloured circle corresponds to one MLVA-16 genotype from a marine mammal species. Numbers in black (23, 24, 25, 69 to 79) indicate the MLVA the panel 1 genotype for the colour circle below. The panel 1 genotype along daughter branches is indicated only when it is different from the proposed parent node (i.e. in cluster A, all strains are panel 1 genotype 24 in subcluster A1 or 77 in subcluster A2). The tentative MLST sequence type (ST23 to ST27) as predicted from strains shared between this study and  is indicated, together with species assignment. The host species colour code indicated is the same as in Figures 1 and 2 (AWSD: Atlantic White Sided Dolphin).
