Gut microbiota-derived isovaleric acid ameliorates influenza virus infection via gut-lung axis.

H9N2 influenza virus infections represent a significant respiratory health concern, yet the functional role of gut microbiota during infection progression remains poorly understood. Here, we show that H9N2 infection causes dose-dependent alterations in gut microbial communities in a mammalian infection model, particularly the depletion of Prevotella species. Prophylactic administration of Prevotella copri improved survival and clinical outcomes in infected mice by restructuring the gut microbiome, promoting beneficial bacteria, and suppressing pathogens.
