Seven days post infection, CFUs of C. rodentium were still lower in the cecum of HF-transplanted mice (p = 0.008; Fig. 3G), while the expression of Muc2, Reg3γ, Dmbt1, mBD3, mBD4 and Lypd8 was not altered between HD- and HF-transplanted mice infected with C. rodentium (S3A). This evidence concerns the gene MBD4 and hydrops fetalis.
