[The antibacterial properties of the intestinal microflora of healthy calves].
Antibacterial properties of bacteria of genera Escherichia, Enterococcus, Bacillus, Lactobacillus, Bifidobacterium isolated from different parts of gastro-intestinal tract of the healthy milk-fed and weanling calves were studied against test-bacteria, microorganisms of the Escherichia genus with and without pathogenic factors as well as the genera Klebsiella, Enterobacter, Proteus, Salmonella, Staphylococcus representatives that had been isolated from healthy and sick calves. Certain tolerance was determined between the groups of bacteria under study and only some strains of lactobacteria and bifidobacteria showed selective antibacterial action on pathogenic and conditionally pathogenic microorganisms, thus stabilizing intestinal microbiota in the gastro-enteric tract of calves.
