Probiotics The definition of Probiotics: -Living micro-organisms that, upon ingestion in certain numbers, exert health benefiting effects beyond inherent general nutrition -The most commonly used probiotics are lactic acid bacteria such as bifidus or lactobacilla -Probiotics are believed to improve the immune response in allergic or infectional conditions
Precosa • The drug Precosa consists of a strain of probiotic yeast, called Saccharomyces boulardii. • It has been shown to be useful against enteropathogens • Most of the proposed mechanisms by which this yeast exerts its beneficial effects on the gut are derived from animal studies and are of theoretical nature.
Possible mechanisms of Precosa • Inhibition of if pathogen adhesion to gut mucosa • Strengthening of enterocyte tight junctions • Neutralization of bacterial virulence factors • Enhancement of IgA on the surface of the gut mucosa
