ICTVdB Tutorial
Index of Viruses

Accessing the Database The ICTVdB is similar to a library catalog, which can be accessed many different ways. For first-time users only one method of accessing the database will be documented in the examples.

Starting at the Home page, information within the ICTVdB is divided into two sections:

  • Classification and Nomenclature of Viruses are accessed by clicking on the Index of Viruses (http://www.ncbi.nlm.nih.gov/ICTVdb/Ictv/) link.
  • Virus Descriptions are accessed by clicking on the Descriptions (http://www.ncbi.nlm.nih.gov/ICTVdb/ICTVdB/) link.

It is recommended that first-time users access the database using the following procedures to learn the nomenclature and family structure of viruses.

Note: Some steps are repeated in each procedure and can be eliminated once you are familiar with navigating the database.
