Microbial Library of Resistant Organisms

Accuratus Labs maintains an extensive library of bacterial and fungal strains, including many “superbugs” or antibiotic-resistant bacteria. Multiple ATCC strains and numerous clinical isolates are available for many of the organisms listed below. Accuratus Labs continuously acquires additional organisms from multiple sources to assure we have the organisms for your testing needs.

If you need testing using an organism that is not in our library, please contact us and we will find it for you.
