    TWiV 1327: Influenza viruses in the MIST
    May 31 2026

    TWiV explains research on human influenza virus transmission that reveals heterogeneous expulsion of infectious virus into air, and how gut bacteriophages dictate inflammation heterogeneity through tuning the phage-bacteria-sphingosine-intestine axis in Crohn's disease.

    Hosts: Vincent Racaniello, Rich Condit, Brianne Barker, and Jolene Ramsey
