00:00Helicobacter pylori is a strain of bacteria that causes stomach ulcers.
00:04The stomach lining is attacked by the Helicobacter pylori bacteria when a person contracts the
00:10infection, and the stomach loses the gastric mucosa layer that shields it from the stomach's
00:14acid. Gastric acid is a digestive stimulant that is produced by the stomach. The stomach
00:20wall is also protected from acid by a membrane known as the mucosa, but when this layer is
00:25removed, it can cause a range of health issues, such as gastritis and stomach ulcers.
