The murine model of influenza virus infection is generally a lethal pneumonitis produced by a highly mouse-adapted virus. However, we infected mice with a less adapted virus and produced a nonlethal disease that involved the airways without producing gross pneumonitis. Changes that occurred in the tracheal epithelium were studied by scanning and transmission electron microscopy. Complete desquamation of the epithelium occurred within 3 days after infection, regeneration began within 5 days, and repair was complete within 2 wk after infection. This model is proposed as an alternative to the lethal pneumonitis for the study of murine influenza and also as a model for the study of repair of the respiratory ciliated epithelium.
