The role of individual members of the family Streptococcaceae in the health of the organism under different types of nutrition

Abstract

Streptococcus bacteria, genera Streptococcus, Lactococcus and Enterococcus, are always isolated from the intestinal contents of children and young mammals. They are mostly beneficial for the host organism and their quantitative and species composition depends on the health statute. The objective of our studies was to continue the work on elucidating the role of the genus Enterococcus in the health of the organism under different types of nutrition. The studies were performed in three stages: 1) determination of the frequency of Enterococci in the digestive tract of humans and animals; 2) establishment of their number in the rectum content of healthy children and adults of different ages (1-3 and 20-80 years) and 3) determination of quantitative and qualitative indicators of Enterococci in the intestines of white rats fed diets with different contents of proteins, fats and carbohydrates
