Effect of non-viable Lactobacillus rhamnosus CRL1505 (HK1505) and its peptidoglycan (PG1505) on the resistance to primary Respiratory Syncytial Virus (RSV) infection. Infant mice were nasally primed with HK1505 or PG1505 during two consecutive days and then challenged with RSV. Non-treated infant mice challenged with the viral pathogen were used as controls. Lung RSV titers (A), changes in body weight (B), and lactate dehydrogenase (LDH) activity and albumin concentrations in bronchoalveolar lavages (BAL) (C) were evaluated on different time points after the viral challenge. The results represent data from three independent experiments. Significant differences between treated and control groups *P < 0.05, **P < 0.01.
