TWiV discusses genetic evidence of susceptible wildlife in SARS-CoV-2 positive samples at the Huanan Wholesale Seafood Market, polio cases in African linked to a new polio vaccine that was designed to not cause the disease, and structural conservation of hepatitis B virus capsid proteins over millions of years despite a shift from a naked to an enveloped capsid.

TWiV provides updates on the new coronavirus causing respiratory disease in China, the current influenza season, and the epidemic of African swine fever, including determination of the three-dimensional structure of the virus particle.

The TWiVeroos deliver the weekly Zika Report, then talk about a cryoEM structure of a plant virus that reveals how the RNA genome is packaged in the capsid, and MIMIVIRE, a CRISPR-like defense system in giant eukaryotic viruses.

The TWiVniks discuss the structure of a virus that reproduces in an extreme environment, long-term consequences of Ebolavirus infection, and VirScan, a method to identify the different virus infections you have had in your lifetime.

Hosts: Vincent Racaniello and James Van Etten Guests: Chantal Abergel and Jean-Michel Claverie Vincent meets up with Chantal and Jean-Michel at the first International Symposium on Giant Virus Biology in Tegernsee, Germany, to discuss their work on Mimivirus,…
