On episode #272 of the science show This Week in Virology, the TWiV team describes aphid control by using a viral capsid protein to deliver a spider toxin to plants, and a human endogenous retrovirus that enhances expression of a neuronal gene. You can find TWiV #272 at www.microbe.tv/twiv.

To the collection of avian influenza viruses known to sporadically infect humans - H5N1, H7N9, H7N2, H7N3, H7N7, H9N2, and H10N7 - we can now add H10N8, recently found in two individuals in China. Avian influenza virus H10N8 was first detected in tracheal aspirates from a 73 year old woman ...

On episode #271 of the science show This Week in Virology, the TWiV crew discusses two reports on viruses that might have crossed kingdoms, from plants to honeybees and from plants to vertebrates. You can find TWiV #271 at www.microbe.tv/twiv.

Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are infected with circoviruses with ...
