Influenza A viral infection linked to gene expression changes in microbiome and brain

In a study of newborn piglets, infection with influenza A was associated with disruptions in the piglets' nasal and gut microbiomes, and with potentially detrimental changes in gene activity in the hippocampus, a brain structure that plays a central role in learning and memory. Maternal vaccination against the virus during pregnancy appeared to offer some protection from those changes in the piglets.
