Assessment of the in vitro inhibitory activity of specific probiotic bacteria against different Escherichia coli strains.

Background: Lactobacilli and bifidobacteria are often associated with health-promoting effects. These live microorganisms, defined as probiotics, are commonly consumed as part of fermented foods, such as yoghurt and fermented milks, or as dietary supplements. Escherichia coli is a gram-negative, rod-shaped bacterium commonly found in the lower intestine of warm-blooded organisms.

The innovative potential of Lactobacillus rhamnosus LR06, Lactobacillus pentosus LPS01, Lactobacillus plantarum LP01, and Lactobacillus delbrueckii Subsp. delbrueckii LDD01 to restore the "gastric barrier effect" in patients chronically treated with PPI: a pilot study.

Background: Gastroesophageal reflux disease is a very widespread condition. In Europe, it is estimated that about 175 million people suffer from this disease and have to chronically take drugs to increase gastric pH. The proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, and esomeprazole are the most widely used drug typology in this regard.
