TWiV reviews resurgence of Lassa fever in West Africa, at least 3 paralytic cases of cVDPV2 in Zimbabwe, CWD from eating prion-laden plants, measles in New Orleans and Broward County Florida, failure of Florida Surgeon General to support vaccination, a measles variant in Switzerland, SARS-CoV-2 persistent infections, leaky blood-brain-barrier for long COVID brain fog, West Nile virus transmitted among mosquitoes by the excreta, and viroid-like colonists of human microbiomes.
From the European Society for Clinical Virology 2022 Conference in Manchester UK, Vincent speaks with Richard Knight about prion diseases and the outbreak of bovine spongiform encephalitis that led to cases of variant Creutzfeldt-Jakob disease in humans.
TWiV revisits chronic wasting disease of cervids and the ability of the prions to infect meadow voles and raccoons, and the suggestion that stochastic assembly of influenza virus particles may play a role in phenotypic diversity.
The TWiV hosts discuss the distribution of prions in the eyes of patients with sporadic Creutzfeldt-Jacob disease, and the origins and evolution of RNA viruses.
The sages of TWiV explain how chronic wasting disease of cervids could be caused by spontaneous misfolding of prion protein, and the role of the membrane protein Axl in Zika virus entry into cells.
Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.
The TWiVerinoes discuss the potential for prion spread by plants, global circulation patterns of influenza virus, and the roles of Argonautes and a viral protein in RNA silencing in plants.
Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.
Vincent, Rich, and Kathy discuss Cotia virus, a new poxvirus, Orf virus infections associated with handling goats and lamb, and the innate immune response to prions.
Vincent, Alan, and Rich review an outbreak of rabies in arctic foxes and reindeer in Norway, and a prion that makes you go antiviral.
