Phylogenetic tree of the isolated H. pylori strains. The evolutionary history was computed using the Neighbor-Joining method with 500 bootstrap replicates. The evolutionary distances were computed using the Kimura-2 method. This analysis involved 408 nucleotide sequences. Evolutionary analyses were conducted in MEGA X⁴⁸ (https://www.megasoftware.net/). References were taken from the Helicobacter pylori MLST Databases. Reference strains are not annotated but colour-coded. The triangle displays bootstrap values from 0 to 1 drawn to scale.
