TWiV reviews an analysis of animal sales from Wuhan wet markets before the COVID-19 pandemic, control of dengue by release of Wolbachia-infected mosquitoes, and fatal dengue acquired in Florida.
The TWiV pro-vaxxers reveal viruses that infect endangered wild salmon, and how iron in host serum modulates dengue virus acquisition by mosquitoes.
The TWiVome explores induction of antiviral responses by repeating patterns of capsids, and a fungus in the mosquito gut that aids dengue virus replication.
The TWiVians present an imported case of yellow fever in New York City, and explain how a dengue virus subgenomic RNA disrupts immunity in mosquito salivary glands to increase virus replication
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.
Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.
The TWiXers discuss a study on vertical transmission of Zika virus by Aedes mosquitoes, and uncovering Earth’s virome by mining existing metagenomic sequence data.
Zika virus spreads in the USA, a Zika virus DNA vaccine goes into phase I trials, and how mosquito bites enhance virus replication and disease, from the friendly TWiFolk Vincent, Dickson, Alan, and Kathy.
Four virologists discuss our current understanding of Zika virus biology, pathogenesis, transmission, and prevention, in this special live episode recorded at the American Society for Microbiology in Washington, DC.
Vincent and Kathy visit Laura Newcomb at California State University San Bernardino, where they talk about Laura’s viral tattoos, and a protein that protects the mosquito brain from lethal flavivirus infection.
