As exemplified for the 120 dpi time point, the global response of the bone marrow to MVMi and MVMp infection may drastically vary: whereas the pool of bone marrow mCD45+ cells was depleted by MVMi but enhanced by MVMp infection with respect to that of uninfected mice (Fig. 4C, left), the pool of CD34+ cells in the bone marrow of uninfected and MVMi-infected mice remained at a higher proportion than in the MVMp-infected mice (Fig. 4C, right). The gene discussed is CD34; the disease is infection.
