Orally administered immunomodulatory lactobacilli can stimulate respiratory immunity and enhance the resistance to primary infections with bacterial viral pathogens. However, potential beneficial effects of against superinfection have not been evaluated. In this work, we showed that feeding infant mice Lacticaseibacillus rhamnosus CRL1505 or Lactiplantibacillus plantarum MPL16 strains reduce susceptibility secondary pneumococcal infection produced after activation TLR3 in tract RVS. The treatment by oral route improved production interferons tract, differentially modulated balance pro- anti-inflammatory cytokines, reduced replication, diminished lung damage. Additionally, demonstrated orally confer longstanding protection Streptococcus pneumoniae effect would be mediated stimulation trained alveolar macrophages. This work contributes revealing mechanisms involved modulation gut–lung axis microbes demonstrating specific strains, through common mucosal immune system, able support development macrophages challenges a inflammatory event mucosa.
