Fig. 3From: CRISPR-like sequences in Helicobacter pylori and application in genotypingCRISPR-virulence typing of 20 H. pylori isolates from PBH (n = 13) and SKH (n = 7) base on binary matrix. Phylogenetic analysis was performed using BioNumerrics 7.6. Similarity (%) between patterns was calculated using the Dice index. The data were sorted using the UPGMA methodBack to article page
