How gut microbiota affect systemic responses to viral infection is still unclear. Here the authors use LCMV mouse infection model to show that a low complexity 12-strains community but not germ-free condition potentiates anti-viral immunity against LCMV beyond that of specific pathogen-free mice, but also aggravates LCMV-induced diseases.
