  • a Probably identical toCandidatus Helicobacter suis. Bacteria with the 16S rRNA sequence present in “H. heilmannii” type 1 have to date been identified in humans, pigs, and nonhuman primates, although the host range is probably more extensive. Other hosts have organisms with the “H. heilmannii” morphology that may represent H. bizzozeronii or otherHelicobacter species not yet identified.

  • b Unpublished data suggest that H. nemestrinae may be identical to H. pylori (see the text).
