The Team with Invincible Values discusses whether dogs or cats passively carry SARS-CoV-2 on hair and foot pads, maternal to fetal transfer of antibodies in infected or vaccinated pregnant women, and evidence that retroviruses infected cetaceans before and after they moved into the oceans.
TWiV reviews evidence that COVID-19 mRNA vaccination of both uninfected and previously infected persons elicits cross-variant neutralizing antibodies, and directed evolution of a bacterial protein to form a virus-like capsid that specifically packages its encoding mRNA.
A TWiV trio reveals the 100 million year old history of bornavirus infections hidden as EVEs in vertebrate genomes, and identification of novel bat coronaviruses that provide evolutionary insight into the origins of SARS-CoV-2.
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.
