H. pylori is a Gram-negative bacterium whose presence in the stomach of infected individuals is linked to the development of several gastric diseases, such as chronic gastritis. Although it is estimated that 50% of the world population is infected by H.

H. PYLORI COLONIZATION: PROTECTION AND PROMOTION OF INFLAMMATORY DISEASES

H. pylori infection is inversely associated with the development of some diseases, suggesting that the presence of these bacteria may also be beneficial to the host, as is the case for reducing the risk of obesity, childhood asthma, inflammatory bowel disease and celiac disease among others.

ROLE OF INFLAMMATION IN H. PYLORI MEDIATED DISEASES

H. pylori infection triggers several adaptative cellular mechanisms in host cells that may favor gastric cancer development and progression [ 108 ].

H. PYLORI COLONIZATION AND ITS ASSOCIATION WITH MICROBIOME SHIFTS

As discussed above, H. pylori infection has been associated both positively and negatively with the development of gastric and non-gastric diseases. Disease development is often linked to chronic inflammatory responses induced by H. pylori, as was discussed in the previous section. However, it is now becoming increasingly clear that H.
