Abstract

Works by many researchers show that for the production of veterinary probiotics, microorganisms obtained from the intestines of animals should be used. Therefore, in the selection of strains for obtaining probiotics, this criterion is important. In the present study, the interest in bacteriocinogenic strains of Escherichia coli is associated with the important role of this bacterium as a component of the intestinal microflora in humans and animals. In this regard, the object of the study is a strain Escherichia coli obtained from a healthy calf.
