Fig. 2From: Whole-genome comparative analysis of Campylobacter jejuni strains isolated from patients with diarrhea in northeastern PolandDendrogram representing similarity of virulence patterns of C. jejuni ST50, ST51 and ST257 strains. The dendrogram was constructed based on presence/absence of virulence genes (n = 143) using UPGMA method and Dice coefficient in NTSYS-pc software. Black, blue and green colors of the tree branches indicate ST50, ST51 and ST257 strains, respectively. The isolates from northeastern Poland are shown in redBack to article page
