Considering our results showing C. rodentium infection exacerbated the deficit in Irgm1-/- myeloid cells in mixed chimera within 10 days post infection (S8 Fig), we revised our experiment by analyzing apoptosis at early stages of infection and also, we attempted to increase the abundance of Irgm1-/- cells in mixed chimera by adoptively transferring WT and Irgm1-/- bone marrow at a ratio of 1:8. This evidence concerns the gene IRGM and infection.
