H. pylori is able to survive in stomach acid because it secretes enzymes that neutralize the acid. This mechanism allows H. pylori to make its way to the "safe" area: the protective mucous lining. Once there, the bacterium's spiral shape helps it burrow through the lining.

∙ 12y agoYour stomach is protected from its acid by a layer of alkali mucus over the epithelium. H. Pylori can colonise underneath this bacteria and in the microscopic pits in your stomach from which enzymes and hormones are produced.

Is stomach ulcer caused by microbe?
no.Stomach ulcer is the result of acid from the stomach entering the duodenum. This is usually caused by the microbacteria Helicobacter Pylori. Stress can increase the likelyhood of a stomach ulcer.
Why the acid in the stomach does not kill helicobacter?
H. pylori is able to survive in stomach acid because it secretes enzymes that neutralize the acid. This mechanism allows H. pylori to make its way to the "safe" area-the protective mucous lining. Once there, the bacterium's spiral shape helps it burrow through the lining. hope this helps :)
What is H. Pylori bacteria?
H. Pylori are implicated in acid peptic disease (acidity).
What is the most common cause for stomach ulcers?
The most common cause of stomach ulcers ( peptic ulcers ) is the destruction of the gastric or intestinal mucosal lining of the stomach by the action of hydrochloric acid ( an acid normally present in the digestive juices of the stomach.
What are most gastric ulcers caused by?
It is usually caused by Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs (NSAIDs). These can break down the stomach's defence against the acid it produces to digest foods.
Are peptic ulcers caused by a virus?
No. They are caused by a few things, one of which is excessive acid production by the acid producing cells in the stomach. Another cause is frequent use of pills such as Aspirin. Another cause is infection with a type of bacteria called Helicobacter pylori (H. pylori).
Does H pylori cause growling in the stomach?
H pylori does not cause growling in stomach. H pylori is associated with acid peptic disease.
What type of bacteria commonly lives in your stomach and cause ulcers?
due to its high acid level the stomach is normally quite sterile with very little bacteria. The bacteria which is known to cause ulcers is helicobacter pylori, also known as H.pylori.
Of what value is urease to helicobacter?
H. pylori are able to fight the stomach acid with urease they release. Urease converts the urea in the stomach into bicarbonate and ammonia, which are strong bases. This creates a cloud of acid-neutralizing chemicals around the H. pylori, protecting it from stomach acid.
Who invented helicobacter?
Helicobacter pylori (H.pylori for short) was first discovered in the stomachs of patients with gastritis & stomach ulcers nearly 25 years ago by Dr Barry J. Marshall and Dr J. Robin Warren of Perth, Western Australia. At the time (1982/83) the conventional thinking was that no bacterium can live in the human stomach as the stomach produced extensive amounts of acid which was similar in strength to the acid found in a car-battery.source: wikipedia
Does acid in the stomach kill germs?
Stomach acid kills some germs, or microbes, but there are some, like Helicobacter pyloris, that do just fine in stomach acid.
What antibiotic is used for a bleeding ulcer?
Ulcers can be caused by a bacteria called Helicobacter pylori (H. pylori). If this organism is present, the ulcer would be treated with a triple medication regimen; to include: Flagyl plus another antibiotic, antacids to neutralize acid in the stomach, a proton-pump inhibitor which will help heal an ulcer by decreasing acid production in the stomach, and Carafate which will coat an ulcer to allow it to heal.
