Abstract
The data relating to determination of antagonistic activity of Lacobacillus reuteri, Lactobacillus helveticus and association of these cultures to opportunistic hospital microflora as the indicator of its probiotic potential are presented in the article. The results of the carried out investigations showed that L. reuteri strains possess equal antagonistic activity to E. coli, Salmonella spp., S. aureus. On the first day the rate of inhibition was in the range of 35 to 42 %, on the second day - from 65 to 72 %. L. helveticus strain possesses higher antibiotic activity relating to the investigated test-strains comparing to L. reuteri. The results of the studies showed that association comprising Lactobacillus reuteri and Lactobacillus helveticus strains possesses higher antagonistic activity to E. coli, Salmonella spp., S. aureus, Kl. pneumoniae than separate strains. So, the conclusion can be made about possibility to use these cultures association at working out new probiotic products and preparations.
