Lemurs are primates found only on the island of Madagascar and a few small neighboring islands. Some of these animals have endogenous lentiviruses in their genomes. How did these viruses infect the isolated lemurs? Madagascar split off from the African continent at least 100 million years ago, when there were ...

Poliovirus by Jason Roberts The global withdrawal of the Sabin type 2 poliovirus vaccine is a test of the feasibility of the plan, declared by the World Health Assembly in 1988, to eradicate all polioviruses. The main vaccine used for the poliovirus eradication effort is an infectious, attenuated preparation called ...

The TWiV team considers whether those who can do, can't teach, and newly discovered viruses of planarians and Aplysia with the largest RNA genomes. <span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span><span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span><span data-mce-type="bookmark" style="display: inline-block; width: 0px; ...

The development of high throughput nucleic acid sequencing tools has rapidly increased the pace of virus discovery in the past 20 years. Yet in that time, while the largest DNA genomes have increased by nearly ten times, the largest known RNA viral genome has only increase in size by a ...
