STUDY OF ANTI-VIRUS ACTIONS OF METABOLITES OF LACTOBACTERIA

The aim: of the work was to study the antiviral activity of the metabolites of the probiotic strain Lactobacillus rhamnosus GG (LGG or ATCC 53103) regarding clinical strains of enteroviruses (Coxsackie B-5, ECNO21) isolated from the feces of intestinal infections. Materials and methods: The object of the study was substrate-dependent cell cultures of HeLa, Vero, Hep-2 lines. The titer of the virus was determined by the presence of a clear cytopathic action (CPA) in the monolayer infected cells of the virus. Results: Determination of the enteric virus infections activity in the culture fluid showed that in samples with the LGG metabolites, the infections activity of the clinical strains of enteroviruses decreased after 24 hours, at 1.5-1.7 (p
