|Etymology:||Genus name: a helix shaped rod. |
Species epithet: named after Konrad Heilmann, who first reported on a large case study of gastrospirilla infections in humans.
|Significance:||[Of minor importance]|
|Micromorphology:||The cell is a spiral with up to nine tightly coiled turns (3.0-6.5 x 0.6-0.7 µm). It has no periplasmatic flagella, but 4-10 bipolar flagella and is motile..|
|Gram +/Gram -:|
|Other Enzymes:||Urease +|
|Fermentation of carbohydrates:||Helicobacter spp. can neither ferment nor oxidize carbohydrates. Exception: H. pylori, which can oxidize glucose to acetate.|
|Disease:||H. heilmannii cause mild chronic gastritis but may also be associated with peptic ulceration in humans. Clinical signifacance in animals has not been proved, but can often be isolated from cats.
|Hosts:||Cat, dog, pig, primates and other carnivors.|
|16S rRNA Seq.:|
||About 35 species have been described within the genus Helicobacter, and this genus is most closely related to Campylobacter, Arcobacter and Sulfurospirillum.H. heilmannii is closely related to H. felis, H. bizzozerini and H. salomonis.|
