In response to the rising threat of antimicrobial resistance (AMR), NCBI built the National Database of Antibiotic Resistant Organisms (NDARO). With NDARO, you can:
- Browse a curated database of AMR genes
- Identify AMR genes in bacterial genomes with AMRFinder
- Identify bacterial genomes with AMR genes in the Isolate Browser
- Submit sequence and phenotype data related to AMR

NCBI is also adding tools to help researchers find known antimicrobial resistance (AMR) protein information in other NCBI databases such as Assembly, Protein, and Nucleotide.
How do I learn more?
You can read our earlier blog post about the Isolates Browser. We also have a Browser Factsheet and an AMR Factsheet. Finally, the NDARO tools and resources page has more details on NCBI’s efforts as well as example searches.
Explore the resources listed above and use the Feedback link on the browser or email to send us your comments. We’d love to hear what you think!
NDARO is a collaborative, cross-agency, centralized hub for researchers to access AMR data to facilitate real-time surveillance of pathogenic organisms. NDARO is part of the National Action Plan for Combating Antibiotic-Resistant Bacteria developed by the White House in 2015.
