Welcome to Antibiotic Resistance Genes Database Home Page

Our motivations in creating ARDB are to:

  • provide a centralized compendium of information on antibiotic resistance
  • facilitate the consistent annotation of resistance information in newly sequenced organisms
  • facilitate the identification and characterization of new genes


ARDB is not being maintained at the moment, though we hope to secure funding to further improve it.

IMPORTANT: An up to date resource for antibiotic resistance is the CARD database at htp:// All data in ARDB are also found in CARD, but CARD is actively being maintained.

All data underlying ARDB are available for download at: Documentation about the provided data is available at

ARDB was updated to Version 1.1 on July 3, 2009.

For large scale resistance genes annotation, a command-line version of resistance genes annotation tool, including the protein database, is available at Here is the documentation (ardbAnnoNotes.pdf) that is also available in the package.

A brief tutorial showing how to use ARDB is available here: tutorARDB.pdf
