Abstract:
:Commensal bacteria are known to provide colonization resistance in the gut. But exactly which ones provide this function? In a recent paper in Science, Kim et al. (2017) revealed that Clostridia added to mouse infant gut microbiota are sufficient to limit colonization of pathogenic Enterobacteriaceae.

杂志文章abstract::Intestinal reovirus infection can trigger T helper 1 (TH1) immunity to dietary antigen, raising the question of whether other viruses can have a similar impact. Here we show that the acute CW3 strain of murine norovirus, but not the persistent CR6 strain, induces TH1 immunity to dietary antigen. This property of CW3 i...
