There is growing evidence that the respiratory tract and gut microbiotas can help regulate the body’s response to invading respiratory viruses, while in a similar fashion, invading respiratory viruses can induce immune responses that alter the composition of the microbiota. Frequently, the microbiota stimulate the immune system in such a way that limits or diminishes the respiratory virus infection as discussed in Ichinohe et al. However, it appears that is not always the case, since some microorganisms have been shown by DE Lastours et al. to increase viral replication in the respiratory tract.
