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. All underlyuing data are available for download at: Documentation about the provided data is available at

ARDB is recently updated to Version 1.1 on July 3, 2009.

For large scale resistance genes annotation, a command-line version of resistance genes annotation tool 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
