Helicobacter pylori (HP) is a gram-negative spirochete found in and below the lining of the stomach lining. HP can survive in the environment of stomach acid. This type of bacteria secretes the enzyme urease to help neutralize the acidity in the stomach. Helicobacter pylori can live and grow in the mucous layer on the surface of the stomach lining. It can cause chronic stomach ulcers, which often develop while not causing any prominent symptoms.

3. Cause

H. pylori is mainly spread from person to person through direct contact with saliva or feces. H. pylori can also be spread through untreated water.
H. pylori bacteria enter the body through the mouth and move into the digestive system. The stomach and stomach acid itself creates an unfavorable environment for many bacteria. But the bacteria H. pylori is specially adapted to survive in the stomach. It produces an enzyme that, through a series of biochemical processes, creates a buffer of low acidity for itself.
Children who are in contact with the source of the disease are very susceptible to infection, in many different ways such as eating unsanitary food, not properly cooked, drinking contaminated water, not washing hands before eating, handling saliva contact: Kissing, sharing food or toothbrushes with someone who has HP .

4. How is the test for H.Pylori?

Invasive testing requires endoscopy: Biopsy and histology. Rapid urease test (chlorine test). Germ inoculation. PCR looks for germ DNA. Non-invasive test: Look for antigens in the stool. Breath test for HP bacteria. When is HP testing ordered?
Ulcerative pathology is confirmed by X-ray or endoscopy. Histological manifestations of lymphoma (malt). Evaluation after treatment of HP infection: Complicated gastric ulcer (hemorrhage, perforation, or obstruction), lymphoma. If symptoms persist after treatment, endoscopy and biopsy should be done to evaluate peptic ulcer disease associated with prolonged HP infection.
