Figure 4

Phylogenetic tree of the first section (1–156 bp) of the alignment showing phylogenetic clustering of 15 generated sequences with the babA2 reference sequences. H. pylori isolates are named as HP-consecutive number (blue), the reference babA2 and babB gene sequences, obtained from publically available NCBI database, are provided with the respective accession numbers (black).
