Here, conventionally housed (Hh-pos) DC-LMP1/CD40 mice showed Enterobacteriaceae blooming, characteristic for dysbiosis during colitis,42,43 but also increased abundance of Peptostreptococcaceae, Turicibacteraceae, and Enterococcaceae, while we observed only increased abundance of F16 in control (Hh-pos) littermates (Figure 4(e), upper panel). The gene discussed is CD40; the disease is colitis.
