A genus-specific PCR showed that these isolates belonged to the genus Helicobacter . Phylogenetic analysis based on 16S rRNA, 60-kDa heat-shock protein (HSP60) and atpA genes demonstrated they formed a novel lineage within this genus. Pairwise 16S rRNA, HSP60 and atpA gene sequence comparisons of the three isolates revealed 99.7, 99.4 and 99.9 % similarity, respectively, among the three isolates; the 16S rRNA gene of isolate A19T shared 98.5 % sequence similarity with its nearest validly named neighbouring species, Helicobacter mastomyrinus (to the type strain MIT 97-5577T). The taxonomic uniqueness of the wild boar isolates was confirmed by protein analysis performed by matrix-assisted laser desorption/ionization time-of-flight MS and by a distinctive biochemical profile. These data indicated that isolates A19T, C21 and F12 represent a novel taxon, for which the name Helicobacter apri sp. nov. is proposed, with isolate A19T (=DSM 28990T=LMG 28471T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001071
