Helicobacter
Helicobacter
Helicobacter (pronunciation: /ˌhɛlɪkoʊˈbæktər/) is a genus of Gram-negative bacteria, possessing a characteristic helical shape. They were initially considered to be members of the Campylobacter genus, but since 1989, they have been grouped in their own genus.
Etymology
The name "Helicobacter" derives from the Ancient Greek words helix (ἕλιξ), meaning "spiral" or "coil", and bakterion (βακτήριον), which is the diminutive of baktron (βακτρον), meaning "stick". This refers to the helical shape of the bacteria.
