The bacteria that is most strongly linked with gastric ulcer formation is H. pylori.
Yes; ulcers are caused by the H. pylori bacterium which can certainly occur in children.
Helicobacter pylori is a common bacterium found in the human stomach. It can colonize the stomach lining and is associated with gastritis, peptic ulcers, and other digestive issues.
H. pylori is the bacteria associated with peptic ulcer disease and gastric cancer.
Ulcers themselves are not infectious, but they can be caused by infections. For example, peptic ulcers are often associated with the bacterium Helicobacter pylori, which can be transmitted through contaminated food or water. Additionally, some ulcers can result from the use of nonsteroidal anti-inflammatory drugs (NSAIDs) or excessive alcohol consumption, rather than an infectious agent. Therefore, while the underlying cause may be infectious, the ulcers themselves are not contagious.
In a sense, a stomach ulcer (gastric ulcer, in medical terms) can be thought of as "the stomach eating itself." Helicobacter pylori is a bacterium associated with stomach ulcers.
Smoking does not cause ulcer formation, but it does cause gastritis, and does cause delayed healing of ulcers.

Certain foods can indeed aggravate ulcers, but food does not cause them - they are caused by a bacterium called heliobactor pylori. Gastritis - a very different thing from ulcers - can be caused by any particularly spic, greasy or heavy food.
Not all ulcers are caused by Helicobacter pylori (H. pylori) infection, but a significant number of peptic ulcers are associated with it. H. pylori is a bacterium that can lead to inflammation of the stomach lining and ulcer formation. Other factors, such as the use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, and stress, can also contribute to ulcer development. Therefore, while H. pylori is a common cause, it is not the sole factor in all cases of ulcers.
The link between bacterium H. Pylori and gastric ulcers was suspected for a long time, but finally proven in an unscientific way by scientist Barry Marshall (1981) who was fed up of not being able to confirm the link so drank a cup full of the bacterium and developed an ulcer a few days later.
He and his partner,Barry Marshall, discovered that bacterium was the cause of stomach ulcers, and re-discovered Helicobacter pylori
