However, the abundance of L. murinus in the AOM/DSS-treated group was lower than that in the control group (p = 0.021 for male Nrf2 KO control vs. male Nrf2 KO AOM/DSS-treated and p = 0.021 for female WT control vs. female WT AOM/DSS-treated) (Figures 8C, D). This evidence concerns the gene NFE2L2 and infectious otitis media.
