Prevalence of the Helicobacter pylori babA2 Gene in Children Mainly Depends on the PCR Primer Set Used

Figure 2

Phylogenetic tree showing three babA2 and three babB gene reference sequences and 15 strains, which tested positive with the 271 bp PCR primer set [14]. Numbers at nodes show aLRT branch support values. 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).
