Abstract

Using light microscopy, the adhesion of probiotic lactobacilli was studied in mixed populations with representatives of the opportunistic intestinal microflora of calves. In the experiments, the adhesion substrate was native cattle erythrocytes (an adequate model of intestinal epithelial cells). It was established that, being in a mixed population, lactobacilli and opportunistic bacteria showed the ability to reduce the adhesive properties of each other. The degree of change in the adhesion indices of microorganisms depended on their species (strain) affiliation and the quantitative ratio in the mixture. The combination of Lactobacillus spp. Strains showed the greatest inhibitory effect on the adhesive activity of opportunistic bacteria; the level of adhesion of the probiotic composition itself under the influence of opportunistic microbes decreased slightly.
