To answer it indirectly, there is very little urea in the stomatch and the toxin VacA opens channels to promote diffusion of urea into the stomatch

What are the properties of H. pylori?
Under the microscope, H. pylori (Helicobacter pylori) is a spiral shaped rod, gram negative, 3*0.5 micrometers in size, and has 4-6 flagella. They are aerobic bacteria that are responsible for 80% of stomach ulcers. Besides microscopically observing stomach (stool) samples, one can also determine the presence of H. pylori by:culture of stomach fluid sampleurea breath testmeasuring antibodies to urease in blood, saliva, or stool. However, these antibodies may persist long after the infection has been eradicated, so it is less useful than the breath test.Another property of the H. pylori allows for the urea breath test. Since H. pylori contains high levels of urease, an enzyme which degrades urea to carbon dioxide (CO2), patients can swallow a dose of urea labeled with C13, then have their breath collected. The Collected exhale (labeled CO2) will then be measured in a mass spectrometer to determine if the concentration of CO2 indicates an H. pylori infection. This is an accurate test for 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.
Test to confirm H pylori?
From experience of having Heliocabacter pylori twice, I can honestly say that H. Pylori is detected by a simple blood test along with a 13C urea test. Both tests are non invasive but urea is far more accurate, extensively endorsed by medical societies as the preferred non invasive test of choice and can be detected at the physicians office by using a device such as the BreathIDIt's nothing to be afraid of, the antibiotics do all the work and cure it in at least 2 weeks. Majority of the people never vomit with this, i know i didn't, you just feel really nauseaus.
What is urease test in microbiology?
When determining the ability of a bacteria to degrade urea by means of the enzyme urease. To diagnose H. pylori and identification of the genus Proteus, Providentia, Kelbsiella, and Morganella by their fast urease activity.
What organism excretes urea?
liver is the the vital part of body which takes part in many processe .it produces urea during the breakdown of glycogen to glucose in order to provide energy to the body . this is not exactly the excretory organ but takes part in excretion process assembly
Would H.Pylori be able to survive in the stomach without urea explain?
Yes
Why can't bacteria survive in the stomach?
H. pylori live in the mucous lining of the stomach. Safe inside there, they are able to fight the stomach acid that does reach it with urease it releases. 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.

What does c-13 test tell you?
The C13 test is the urea breath test. It picks up the presence of Helicobacter pylori bacteria in the stomach. It is used as a diagnostic tool for gastritis and some types of ulcers.
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.
For which of the five hydrolysis tests would a positive test result be expected for the etiologic agent of gastric ulcer's helicobacter pylori?
Urea
What is urease breath test?
Urea Breath Test for Helicobacter pylori is a simple, non-invasive way of testing for the bacterium responsible for many cases of stomach and duodenal ulcer.Certain medications that may affect the test need to be excluded, for up to 30 days before the test. A small dose containing Carbon-13 Urea (13C urea) is taken by mouth, and a breath sample is collected 30 minutes later. The test is not radioactive and can be performed on children, or pregnant women.
Can H Pylori cause stomach bloating?
Bloating is a sign of an h. pylori infection. Most people who have an active infection show no signs, however. There is no one symptom or set of symptoms which may be directly attributed to H. pylori infection. Some of the symptoms that may be associated with infection include nausea, abdominal pain, esophageal reflux, dyspepsia (upper and mid-abdominal pain), bloating, or belching. Conversely, one may be completely asymptomatic for many years. The only way to know for sure if you have H. pylori is to be tested. The Urea Breath Test offers a simple, noninvasive testing option. Ask your physician for more details.
What causes erosive and hemorrhagic gastritis?
The patient's clinical history may be particularly important in the diagnosis of this type of gastritis, since its cause is most often the result of chronic use of NSAIDs, alcoholism, or abuse of other substances.
