5 Must Know Facts For Your Next Test
Helicobacter pylori can survive in the acidic environment of the stomach due to its production of urease, which neutralizes stomach acid.
This bacterium is classified under the phylum Proteobacteria and is a common cause of chronic gastritis.
H. pylori infection can be diagnosed through non-invasive tests such as urea breath tests, stool antigen tests, and blood antibody tests.
It has a unique ability to alter the pH around it by converting urea into ammonia and carbon dioxide.
The presence of H. pylori significantly increases the risk for developing gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma.
