- ⏰ According to Sürbaum et al. (2002), this species is an earlier heterotypic synonym of Helicobacter nemestrinae Bronsdon et al. 1991. Publication: Suerbaum S, Kraft C, Dewhirst FE, Fox JG. Helicobacter nemestrinae ATCC 49396T is a strain of Helicobacter pylori (Marshall et al. 1985) Goodwin et al. 1989, and Helicobacter nemestrinae Bronsdon et al. 1991 is therefore a junior heterotypic synonym of Helicobacter pylori.
