Which genus of bacteria causes stomach ulcers?

Answer 1

Heliobacter is the primary cause of stomach ulcers

That should be spelled helicobacter. Specifically, the bacteria is called helicobacter pylori. The organism is helical and is found near the pyloric valve (between stomach and small instesine). pyloric = gateway (greek).

Answer 2

The stomach bacteria most often responsible for causing ulcers in humans is Helicobacter Pylori. This bacteria can inhibit the stomach and the early portion of the small intestines. Currently, it is estimated that over half the world's population harbor this bacteria (although its prevalence in developed countries is lowering). Its released enzymes causes inflammation in the stomach lining and leads to the development of ulcers.

Answer 3

Helicobacter pylori is the genus of bacteria that is most commonly associated with causing stomach ulcers in humans. It is a spiral-shaped bacterium that can colonize the stomach lining and lead to inflammation and ulcer formation.
