More than 500 different species of bacteria inhabit the intestinal tract of the human body. The greatest quantity and variety in the colon. The relationship between microorganisms and macroorganisms are multifaceted and are based on balance and mutual cooperation.

Violation of this balance may be as a result of developing disease and is a prerequisite for unlocking pathology. Therefore, the scientific community has turned its gaze to establish the objective significance of the intestinal microflora in maintaining human health.

Infants are born with a sterile digestive system. Colonization of the latter with good bacteria begins with the passage of the newborn during birth roads. It has been shown that children born under operating mechanism have less colonization of gastrointestinal tract by microorganisms of the end of the first week.

In the digestive system establishes a dynamic balance between benign bacteria. Their appearance and proportion in various departments of the gastrointestinal tract are not random. In normal conditions, the pathogen attempts to disrupt the harmony of the intestinal microflora is unsuccessful.

Benign block the multiplication of microorganisms and the attachment of pathogenic bacteria to the surface of the intestine. Furthermore, the intestinal microflora stimulates local immunity and the production of mucus in the digestive tract.

In light of these proven facts, studies have been conducted to establish the extent reasonably probiotic treatment of various gastrointestinal diseases in childhood. Probiotic means “for life.” Bulgarian yoghurt is considered the first probiotic worldwide.

Probiotics are microorganisms that restore harmony in the balance and functioning of the normal intestinal microflora. In the studies conducted today, probiotics are added in the milk or in the formulas for small children with gastro-intestinal pathology. The aim is to determine whether probiotics accelerate parallel ongoing healing process.
