The TWiV-osphere introduces influenza D virus, virus-like particles encoded in the wasp genome which protect its eggs from caterpillar immunity, and a cytomegalovirus protein which counters host restriction factors that prevent establishment of latency.

Stephanie joins the super professors to discuss the gut virome of children with serious malnutrition, caterpillar genes acquired from parasitic wasps, and the effect of adding chemokines to a simian immunodeficiency virus DNA vaccine.

Vincent, Dick, Alan, and Max Gottesman discuss an unusual wasp-virus symbiosis, influenza transmission and absolute humidity, how mosquitoes survive Dengue virus infection, and viruses of bacteria.
