*2.5.10 Helicobacter pylori*

The most common and worst bacterial infection found in human is the *Helicobacter pylori*. It causes a number of diseases like peptic ulcers, chronic gastritis, lymphoma, gastric adenocarcinoma and number of other diseases not related to gastrointestinal tract. Probiotics prevent the *H. pylori* infection by enhancing the immunoregulation functions that works as antagonistic to infection caused by *H. pylori* [61–63]. Many studies reported that *H. pylori* growth and gastritis infection can be minimized but the causative organism cannot be completely removed. It is noted that prebiotics plays their role for the suppression of *H. pylori* as well as they also enhance the efficacy of eradication therapy by stopping the side effects caused by antibiotics thus improving compliance [64]. *saccharomyces boulardii* is found helpful in reducing the symptoms of *Helicobacter pylori*.
