CLEVER

Classification of Latent and Established Variants of Extant antibiotic Resistance

CLEVER is a database resource for antibiotic resistance genes (ARGs). It contains information on verified ARGs gathered from ResFinder, CARD and ResFinderFG. It also contains predicted ARGs from the following collections:

  • Inda-Díaz JS, Lund D, Parras-Moltó M, Johnning A, Bengtsson-Palme J, Kristiansson E. Latent antibiotic resistance genes are abundant, diverse, and mobile in human, animal, and environmental microbiomes. Microbiome. 2023;11(1):44. Published 2023 Mar 8. doi:10.1186/s40168-023-01479-0

The current CLEVER version is 1.0, released on March 20, 2026.

The database can be downloaded from here for offline usage, or browsed in the tables below. The code base is also hosted on GitHub.
