[Effect of probiotic lactic acid bacteria strains on virus infection]
Abstract:
The effect of probiotic lactic acid bacteria strains on viral infection was studied in experiments in vivo. It was shown that in investigations microbial substance based on living cells of L. plantarum and S. salivarius subsp. thermophilus strains manifested antiinfluenzal activity under administration of 0.3 ml of cultural medium per os at a dose of 3 x 10(8)/CFU mouse and antiherpetic activity at a dose of 0.3 x 10(9)/CFU mouse. The probiotic effectiveness was shown on the model of genital herpes of guinea-pigs at concentration of 1 x 10(9) cells/g.p. It was statistically established, that the lactic acid bacteria inhibited reproduction of HIV at a dose of cells of 0.1 x 10(9)/CFU ml.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
