B. fragilis PSA protects against HSE. a Experimental regimen: In all experiments, PSA (six doses, 50 μg/mouse) or PBS was given orally before HSV infection on day 0 and thereafter daily ip injections of ACV from day 4 pi for 7 days. Survival of wildtype (WT) or Rag mice pre-treated with b B. fragilis, PSA or c PBS, (n = 8–17 mice/group). ****p < 0.001, WT + B. fragilis/PSA vs. Rag + PSA; ns: not significant, WT + PBS vs. Rag + PBS as determined by log rank (Mantel–Cox) test
