ABSTRACT
Certain bacteria, yeasts, and protozoa that are food contaminants can cause food-borne illness and are pathogenic.Actually, whenever solid food is introduced to the infant's diet, the microbiota change. Altogether there are about 8,000 polyphenol compounds that are in food that affect the metabolism of the gut microbiota. Probiotics are thought to improve the epithelial barrier function of the gut and modulate the immune response of the intestinal mucosa as well as alter the composition of the microbiota. However, it could also be due to shifts in the microbiota that alter the production of appetite-stimulating or satiety signals generated in the gut by microbial activity. In addition, in these rats, the gut microbiota dysbiosis was characterized by an overall decrease in microbial diversity. The immune system is part of the body's response to injury and it is important to understand this response as it relates to the interactions between the microbiota and the host.
