Host behavior alteration by viruses is known to assist the development of another organism. An example is a parasitoid wasp that injects viruses along with eggs into a caterpillar. The viral genomes encode proteins that subvert the caterpillar immune response, allowing the wasp larva to develop. A similar strategy may enable safe development of a …

On the final episode of the year of the science show This Week in Virology, the TWiV team reviews twelve cool virology stories from 2012. You can find TWiV #213 at www.microbe.tv/twiv.
In episode #21 of This Week in Virology, Vincent, Dick, and Alan are joined by Max Gottesman, who has researched viruses of bacteria – bacteriophages – for many years. They discuss an unusual wasp-virus symbiosis, influenza transmission and absolute humidity, how mosquitoes survive Dengue virus infection, and bacteriophages. Click the arrow above to play, or …
