Probiotics are expected to enhance the body'simmunefunctionThe purpose of this study was to assess the effects of dietary intake of fermented yogurt with Delbruck Lactobacillus sp.Bulgarian Lactobacillus OLL1073R-1 (OLL1073R-1) on winterpreventioninfluenza and immunological marker activationrandomly assigned 961 women aged 20-71 to yogurt groups (n - 479) or control groups (n s 482)Participants in the yogurt group drank 112 milliliters of oLL1073R-1 fermented yogurt beverage daily for 16 weeks, while the participants in the control group did not drink yogurt during that timeThroughout the trial, all participants were instructed not to drink any other types of yogurt or fermented dairy productsAssess the cumulative incidence of influenza at baseline and after 16 weeks and examine immunological markersresults showed no significant difference in the incidence of influenza in the two groups (cumulative incidence of influenza: 7.5% yogurt, 7.7%) of the two groups)Natural killing (NK) cell activity did not show significant intervention effect (P - 0.11), while the intervention effect on serum interferonium (IFN-xenon) was significant (P s 0.03)Other immunological markers did not show significant interventional effects, the results show that the consumption of OLL1073R-1 yogurt did not show significant role in flu prevention, nor significantly enhance the activity of NK cellsHowever, after ingesting the yogurt, the level of IFN-stomp ingons increases
