Astroviridae sequence database from Nick Knowles at the Institute for Animal Health, Pirbright Laboratory, UK.
Astroviridae - Taxonomy, properties and images from the Universal Virus Database, authorised by ICTV (International Committee on Taxonomy of Viruses) which has developed a universal taxonomic scheme for viruses.
The goal of the ICTVdB is to describe all viruses of animals (vertebrates, invertebrates, protozoa), plants (higher plants and algae), bacteria, fungi, and archaea from the family level down to strains and isolates.
