The rapid clearance of acute viral infections is a consequence of robust host defenses. Survivors of acute infections are usually immune to infection with the same virus. If the immune response is so effective, why do some viral infections - such as the common cold or influenza - occur repeatedly? ...

Endoparasitic wasps inject their eggs into moth or butterfly larvae, which are cannibalized as the eggs mature and develop into adult wasps. The wasp larvae survive in the caterpillars because the eggs are injected together with virus particles called polydnaviruses. These viruses replicate in cells of the caterpillar, and their ...

The sequence of all known rhinovirus genomes reported in Science last week is an important advance for the field. Analyses of the sequences have revealed new relationships among the viruses, evidence for recombination, a new viral species, and conserved regions of the genome. These findings will be extremely valuable for those ...
