“…Крім того, доведено, що різні штами молочнокислих бактерій, зокрема Lactobacillus рlantarum, можливо використовувати у м'ясній промисловості як біологічний бар'єр, що дозволить уповільнити розвиток патогенної мікрофлори (Vinnikova et al, 2015). При цьому біологічна ефективність пробіотичних препаратів визначається не лише властивостями використаних штамів мікроорганізмів, а й технологією їх отримання, де головним і вкрай важливим є досягнення максимального виходу життєздатних клітин бактерій і синтезованих біологічно активних речовин (Safronova, 2015).…”

Data on the study of the effect of a consortium of lactic acid bacteria on the morphological parameters of blood and the state of the intestinal microflora of white rats using a composition of probiotic strains of L. lactis, Lb. plantarum and E. durans SB18 in a ratio of 50:40:10. Thus, when determining the morphological parameters of the blood of rats at 14 days of use found a positive effect of probiotic strains of lactic acid bacteria on the hematopoietic function of laboratory animals. In particular, a significant increase in hemoglobin concentration, erythrocyte count, leukocyte count and hematocrit value was found by 14.9, 14.0, 22.5 % (P < 0.05) and 5.7 %, respectively, compared with the control group. In addition, the use of the drug for 14 days caused an increase in the average concentration of hemoglobin in the erythrocyte (MCНS) by 9.8 % (P < 0.05) and a tendency to decrease the average hemoglobin in the erythrocyte (MCН) and the average erythrocyte volume (MCV) by 0.45 and 9.0 %, respectively, compared with the control group. Both central and peripheral organs of the immune system were also significantly affected. In particular, the relative weights of the thymus and spleen increased by 21.1 (P < 0.05 ) and 9.8 % (P < 0.05), respectively. When determining the leukogram of peripheral blood of rats, it was found that the use of the study drug in animals of the experimental group caused a tendency to increase the number of neutrophils, lymphocytes and monocytes by 6.0, 0.5 and 19.8 %, respectively, with a slight decrease in eosinophils. The use of a composition of a consortium of lactic acid bacteria stimulated an increase in lacto- and bifidobacteria content of the large intestine of white rats. In particular, a significant increase in the number of bifidobacteria and lactobacilli was found by 4.3 and 5.2 % (P < 0.001), respectively, relative to the animals of the control group. In addition, 14-day application of the studied composition of probiotic strains contributed to a probable reduction in the number of opportunistic and putrefactive microflora. The number of Escherichia coli, Staphylococcus aureus and fungi of the genus Candida significantly decreased relative to control by 4.7 (P < 0.01), 2.6 (P < 0.05) and 13.3 % (P < 0.001), respectively, all this indicated the recovery of the body of laboratory animals. The positive effect of lactic acid bacteria of the formed composition persists until the 21st day of the experiment.
