Fig. 2From: Correction to: The pathogenic intestinal spirochaete Brachyspira pilosicoli forms a diverse recombinant species demonstrating some local clustering of related strains and potential for zoonotic spreadMinimum spanning tree showing the origin of the B. pilosicoli strains. Each node corresponds to a sequence type (ST). The lines between STs show inferred phylogenetic relationships and are represented by bold, continuous and continuous thin lines according to the number of allelic mismatches between profiles. The country of isolation is shown by coloured circle as indicated in the legendBack to article page
