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.
On episode #172 of the podcast This Week in Virology, Vincent and Kathy discuss how a virus may cause disease distant from its replication site, then review a day in the life of a senior microbiology professor. You can find TWiV #172 at www.microbe.tv/twiv.
