Probiotics have been defined as live microbial food supplements that have been shown to benefit human health. Probiotic products are marketed widely throughout the world. Until recently, probiotics were mainly selected on the basis of technological properties and resistance to acid and bile and were used in products aimed at promoting the well-being of consumers. However, now research efforts are focusing on the development of probiotics with special functional properties. Lactobacillus gasseri OLL2716 (LG21) was selected as a promising probiotic for Helicobacter pylori infection by in vitro and animal studies. The effects of yogurt containing LG21 on H. pylori infection in humans were examined. The ingestion of yogurt containing LG21 decreases the number of H. pylori and alleviates mucosal inflammation in the stomach. LG21 was shown to be effective as a probiotic for H. pylori infection.
