The aim of work was to determine antibacterial activity of Lactobacillus casei ІМV В-7280 probiotic strain on the experimental urogenital tract infection of mice. The influence of intravaginal and/or per os administration of this strain once per day during 7 days on the microflora of vagina, kidneys and intestinal contents of Staphylococcus aureus 8325-4 infected mice was studied.

It was established, that in cases of experimental staphylococcal infection of urogenital tract L. Casei IMV B-7280 had effective antagonistic activity against S. aureus 8325-4 and opportunistic bacteria. After L. casei IMV B-7280 introduction into infected mice reduction or complete elimination of S. aureus 8325-4 in vagina, kidneys and intestinal contents in different periods of observation was established. Under the influence of L. casei ІМВ В-7280 the number of coliform bacteria, streptococci and staphylococci in the vagina was normalized, and fungal flora — decreased even in comparison with intact mice. Normalization of kidneys microflora was also observed. In the intestinal contents of infected mice trea ted with L. casei IMV B-7280 the number of streptococci did not change, staphylococci number decreased, but the number of fungal and coliform flora remained relatively low during the observation period.

L. casei IMV B-7280 probiotic strain is promising to create immunobiotics with antibacterial action, which can be used for the prevention and treatment of urogenital infections caused by opportunistic microorganisms.

Key words: antibacterial activity, immunobiotics, Lactobacillus casei, Staphylococcus aureus.
