It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another ...

On episode #258 of the science show This Week in Virology, Matt joins the TWiV team to discuss the discovery of a SARS-like coronavirus in bats that can infect human cells, and what is going on with MERS-coronavirus. You can find TWiV #258 at www.microbe.tv/twiv.

The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into cells. I have written ...

On episode #257 of the science show This Week in Virology, the TWiV team consider how the kinase mTOR modulates the antibody response to provide broad protection against influenza virus, and explore the problems with scientific research. You can find TWiV #257 at www.microbe.tv/twiv.
