    Abstract

    The ability of probiotics to balance intestinal microbes and to modulate gut immune system has been reported for several probiotic strains. In the present study, Lactobacillus rhamnosus strain VTT E-97800 (E800) or L. rhamnosus Lc705 (the latter in combination with Propionibacterium freudenreichii ssp. shermanii JS) were separately administered to healthy adult volunteers ( in both study groups) in a whey-based fruit juice. Survival of the potentially probiotic L. rhamnosus strains in the GI-tract and their effect on intestinal well-being and peripheral immune parameters were assessed. Both L. rhamnosus strains were recovered in high numbers in faecal samples during the consumption period and with few exceptions they were not detected after the 2 weeks follow-up period. Consumption of the juice supplemented with either of the L. rhamnosus strains did not have significant effect on faecal consistency or defecation frequency. No changes were observed in the immunological parameters (number or immunoglobulin A-, G- and M-secreting cells, expression of Fcα-receptor or complement receptors 1 and 3), except for a slight decrease in the number of IgA secreting cells during ingestion of the juice supplemented with L. rhamnosus Lc705 and P. freudenreichii ssp. shermanii JS. The results indicate that L. rhamnosus strains E800 and Lc705 had good survival ability in the GI-tract when administered in a whey-based fruit juice matrix. No adverse effects on intestinal function or on studied immunological parameters were observed during consumption of the whey based juice drink supplemented with the potential probiotic strains.
