Viruses - Size

Transcript from “Viruses,” National Center for Macromolecular Imaging
Biological viruses were discovered about one hundred years ago. The invention of the electron microscope made them visible. Bacteria, much larger microorganisms, were seen 300 years earlier by the light microscope. Viruses are the smallest living entities that can reproduce.

Additional Virus information:
Rice Dwarf is one of the most economically damaging disease casing viruses of rice plants in Southeast Asia. Rice Dwarf virus belongs to the family Reoviridae, which also includes some viruses that infect the gastrointestinal tract. Rice Dwarf virus primarily is transmitted by leafhopper insects and can replicate in both its plant host and insect vector. Viruses in the family of Reoviridae live in a variety of plant, animal and insect hosts. Members of the family are varied in their structure but share similar replication mechanisms.
