There are many examples of viruses with segmented genomes – like influenza viruses – but these genomes segments are packaged in one virus particle. Sometimes the genome segments are separately packaged in virus particles. Such multicomponent viruses are commonly found to infect plants and fungi, but only recently have examples of such viruses that infect animals …

Although the use of the live, attenuated (Sabin) poliovirus vaccines has been instrumental in nearly eradicating the virus from the planet, the rare reversion to virulence of these strains has lead to the World Health Organization to recommend their replacement with inactivated poliovirus vaccine (IPV). Unfortunately IPV is also not without shortcomings, including high cost, failure …

Volatile organic compounds that are emitted by plants – which play important roles in attracting insects – can be altered by virus infection. Infection by cucumber mosaic virus (CMV) increases the emissions that attract aphids, but the virus-altered plant juices are not so tasty, so the insect quickly leaves to spread virus to other plants (listen to …
