The human gut microbiome appears to play diverse roles in host physiology, metabolism, and immunity. Most conclusions about what the trillions of bacteria in our intestines actually do come from studies in mice, or correlative studies in humans. An exception is an investigation in humans which shows that antibiotic-mediated alteration of the fecal microbiome* interferes with the antibody response to influenza vaccine.

Viruses and bacteria are both present at mucosal surfaces and it is not surprising that they interact in many ways. Sometimes members of the gut microbiome help viruses to infect cells, exemplified by poliovirus, reovirus, and mouse mammary tumor virus. The opposite also happens: segmented filamentous bacteria can prevent and cure rotavirus infection.
