When the resistance to pneumococcal infection; the lung injury; and the levels of BAL IFN-β, IFN-γ, and IL-10 from young animals receiving L. rhamnosus IBL027, L. rhamnosus CRL489, or L. plantarum CRL1506 and challenged with pneumococci 20 days after poly(I:C) administration were compared to controls, no differences were found for any of the evaluated parameters (Figure 5C).
