Evaluation of antagonistic activity of strains of lactic and bifid bacteria, metabolite producers, as well as the treatment and prophylactic efficacy of Laktimet and Batsinil probiotics was realized in the conditions of the Republic of Belarus. In course of study there were estimated 29 strains of lactic acid bacillus of different kinds, 13 strains of bifid bacteria and 35 strains of bacillus (Bac. subtilis and Bac. pumilis). There were studied 3 strains of bifid bacteria: Bifidobacterium adolescentis MS-42; Bifidobacterium adolescentis BIM V-01; Bifidobacterium adolescentis BIM V-87; 2 strains of lactic acid bacillus: Lactococcus lactis subsp. Lactis BIM V-132, Lactococcus casei subsp. rhamnosus BIM V-189; and 6 strains of Bacillus subtilis. Research results showed that the main part of the studied strains had steady antagonistic activity to test-cultures of opportunistic pathogenic bacteria. Zone of growth delay of test-cultures of the main quantity of strains (from 54 up to 92%) was from 11 up to 30. Research results showed that application of cell-free probiotics Laktimet and Batsinil promoted the increasing of resistance by means of increasing or lowering of total protein, insignificant increasing of blood serum bactericidal activity and increasing of phagocytic activity of leukocytes on 7,3%
