“…Метаболиты в качестве самостоятельных препаратовметабиотиков имеют ряд преимуществ технологического и терапевтического характера в сравнении с традиционными клеточными пробиотиками, сферу применения которых они конкурентно полностью охватывают, а по потенциалу органоспецифического действия значительно превосходят. К их преимуществам следует отнести: высокую биодоступность, отсутствие конфликта с собственной микробиотой макроорганизма, отсутствие латентного периода для реализации биологического эффекта, безопасность, более высокие потребительские свойства лекарственных форм и сроки годности [4][5][6].…”

Objective of the study: comparative evaluation of the bacteriotropic activity of Actoflor-S metabiotic and the exometabolic bifidobacteria complex.Materials and methods: in our work we used Actoflor-S dietary supplement as oral solution in 2 ml drop tubes (Solopharm). As a comparator drug, we used an exometabolite complex from the culture fluid of strain Bifidobacterium bifidum 1 obtained by method of ultrafiltration using separation apparatus with HOMM 15 kDa. We studied the stimulating effect of metabolite compositions on the acid forming activity and dynamics of the accumulation of lactobacilli Lactobacillus plantarum 8P-A3. Antagonistic activity against enterobacteria was determined in the test of inhibition of bioluminescence of the indicator strain Escherichia coli lum+ and quantified as an index of antibacterial activityResults and discussions. A comparative study of the effects of metabiotics on the acid forming activity of lactobacilli showed that both drugs have a pronounced stimulating effect on the probiotic strain L. plantarum. A comparative study of the effects of metabiotics on the model test strain of enterobacteria showed that whole preparations quickly and significantly (by more than 90%) inhibit the bioluminescence of E.coli lum+. Preparation dilutions 1:10 and 1:100 discovered significant differences in their activity. Given equal pH values (5.8 ± 0.1), Actoflor-S (dilution 1:10) inhibited the luminescence of E. coli lum + to a greater degree, exceeding almost 2 times the indicators of the metabolite bifidobacteria complex. It is revealing that Actoflor-S diluted 1:10 is not inferior to the whole preparation in terms of the level of effect on the test strain culture. What calls attention to itself is that large dilutions of UFLC of bifidobacteria after a short period of inhibition of luminescence of E. coli lum + have a stimulating effect. There is evidence that effect of inhibition of the luminescence of the control culture is dose-dependent.Conclusion. The results of a comparative examination of the bacterial action profile of the native exometabolites complex and Actoflor-S preparation confirm the presence of combination of the necessary inhibitory and stimulating activity against various agents of the microbiota. Creation of the metabiotics line based on Actoflor-S preparation with variability of biological properties and specialized for the management of various dysbiotic conditions show promise. An additional inclusion of native exometabolites of bifidobacteria and/or lactobacilli into the formula of artificial compositions will make it possible to expand the spectrum of the positive effect of probiotic preparations on the microorganism.
