Antibacterial and immunomodulating properties of Lactobacillus delbrueckii subsp. Bulgaricus IMV B-7281, Lactobacillus casei IMV B-7280, Lactobacillus acidophilus B-7279 IMV, Bifidobacterium longum VK1 and Bifidobacterium bifidum VK2 strains were determined at the experimental model of staphylococcal infection of mice. It was established that under the influence of these strains it was significantly reduced the number of Staphylococcusaureus colonies, which were seeded out from kidneys of infected mice. At the same time after introduction by mice with staphylococcal infection of separate probiotic strains of lacto- and bifidobacteria it was observed increasing of the CD4/CD8 immunoregulatory index, and also the number of CD19+ - and CD25+-cells in spleen. Lactobacillus delbrueckii subsp. bulgaricus IMV B-7281, Lactobacillus casei IMV B-7280, Lactobacillus acidophilus B-7279 IMV, Bifidobacterium bifidum VK2 and Bifidobacterium longum VK1 strains found to be perspective for probiotics creation, that could be effective against staphylococcal infection and for the immunity correction.

Key words: immunity, interferon, Lactobacillus, Bifidobacterium, Staphylococcus aureus, mice.
