The influence of diets containing proteins of different origins on the level of faecal Streptococcus spp.

Abstract

The work aimed to study the influence of proteins of different origins on the level of faecal Streptococcus. Three series of experiments were performed on 45 model animals (Guinea pigs). The optimal level of Streptococcus is best maintained with diets containing a predominance of proteins of animal origins, primarily fish protein. These proteins contribute to a substantial decrease in conditionally pathogenic Streptococcus, for example, Enteroccocus fecalis (per average with 48.32%, 46.65%, and 44.45% in conformity with the concentration of protein of 10%, 14%, and 16%).
