Vincent and Rich return to the University of Texas Medical Branch at Galveston to speak with Dennis Bente, Shannan Rossi, Nikos Vasilakis, and Scott Weaver about their work on viruses transmitted by mosquitoes and ticks.
For the first TWiV of 2020 we reveal that microbiome depletion with antibiotics alters the immune response to influenza vaccine, and how successive blood meals facilitate virus dissemination in mosquitoes and transmission potential.
Vincent speaks with virologists at the University of Nevada at Reno about their careers and their work on herpesviruses, arboviruses, and the development of diagnostics for infectious diseases.
The TWiV pro-vaxxers reveal viruses that infect endangered wild salmon, and how iron in host serum modulates dengue virus acquisition by mosquitoes.
The TWiV Masters discuss serologic evidence of Ebolavirus infection in a population with no outbreaks, and the set of endogenous viral elements in the mosquito genome.
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.
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.
Vincent meets with members of team ZEST at the University of Wisconsin Madison to discuss their macaque model for Zika virus pathogenesis.
