Daniel Griffin provides a clinical report on COVID-19, superspreading potential of SARS-CoV-2 in Hong Kong, structure of virion glycoprotein of a commmon cold coronavirus reveals changes driven by prolonged circulation in humans, and listener email.
Daniel Griffin provides a clinical report on COVID-19, followed by a review of the findings that children shed as much SARS-CoV-2 viral RNA from the respiratory tract as older patients, the lineage giving rise to SARS-CoV-2 has been circulating in bats in China for decades, and answers to listener questions.
From the NIH campus (recorded February 2020) Vincent and Rich meet with Eugene Koonin to discuss his theories on the evolutionary origins of viruses.
The TWiV team returns this week to SARS-CoV-2019 coverage to review the latest epi curves, the fatality rate, furin cleavage site and receptor binding domain in the spike glycoprotein, related CoV recovered from pangolins, evidence that the virus did not escape from a laboratory, and many more questions sent in by listeners.
Vincent, Kathy and Rich travel to ASM Microbe 2018 in Atlanta where they speak with Stacy Horner and Ken Stapleford about their careers and their research.
The TWiVome deconstructs the evolutionary history of RNA viruses, and immune promotion of murine norovirus pathogenesis by replication in intestinal tuft cells.
The TWiVanguardians take on Bodo saltans virus, a leviathan which infects an abundant flagellated eukaryote in Earth’s waters.
The TWiV team reveal the origin of the poxvirus membrane, and how a retrovirus drove the development of the placenta of a lizard.
Sharon and Scott return to TWiV for a Zika virus update, including their work on viral evolution and spread, and whether pre-existing immunity to dengue virus enhances pathogenesis.
The TWiV scientists reveal that mosquitoes transmit different West Nile virus populations with each blood meal, only to have the diversity purged in a bird host.
