LAB and PAB have also been studied for their probioticproperties but little is still known about their individual and/or synergistic beneficial effects within dairymatrices. In the context of a rising incidence of Inflammatory Bowel Diseases, it has become crucial toevaluate the immunomodulatory potential of bacteria ingested in large numbers via dairy products. Wetherefore selected different strains and combinations of technological LAB and PAB. We determined theirimmunomodulatory potential by IL-10 and IL-12 induction, in human peripheral blood mononuclearcells, on either single or mixed cultures, grown on laboratory medium or directly in milk. Milk wasfermented with selected anti-inflammatory strains of LAB or PAB/LAB mixed cultures and the resultingbacterial fractions were also evaluated for these properties, together with starter viability and optimumtechnological aspects. The most promising fermented milks were evaluated in the context of TNBS- orDSS-induced colitis in mice. The improvement in inflammatory parameters evidenced an alleviation ofcolitis symptoms as a result of fermented milk consumption. This effect was clearly strain-dependent andmodulated by growth within a fermented dairy product. These findings offer new tools and perspectivesfor the development of immunomodulatory fermented dairy products for targeted populations.
