The best known speciesof this genus is Helicobacter pylori which infects humans and is responsible for most cases of peptic ulcerand chronic gastritis; it also serves as the type speciesof the genus.

Bacteria belonging to this genus are susceptible to standard antibioticssuch as penicillin, are microaerophilic(require small amounts of oxygen), and are fast moving with multiple flagella.

Initially, these bacteria were considered to be members of the genus Campylobacter, but since 1989they are grouped in their own genus (Goodwin 1989).
