Antimicrobial-Resistant Reference Materials

Drug resistance is on the rise

Antimicrobial resistance (AMR) is a serious health concern that has contributed to increases in morbidity, mortality, and healthcare expense. Support the prevention and treatment of these infections with a complete set of solutions from ATCC:

  • Strains from various clinical and environmental sources
  • Primary cells for drug toxicity screening studies
  • Media and reagents to support cellular growth

These products are ideal for the development, verification, and evaluation of rapid detection methods, innovative therapeutic techniques, novel antibiotics, and updated sterility protocols. Check out the resources below to find products relevant to your research, or:

Download our white paper to learn more about the importance of antimicrobial-resistant reference strains in reducing the emergence and spread of AMR infections.

Global Priority Superbugs

The ATCC® Global Priority Superbugs collection comprises a targeted set of recent, antimicrobial-resistant clinical isolates that support drug discovery and assay development. Each strain in the collection has validated genotypic and phenotypic activity against a variety of critical drug classes, and is provided with susceptibility data, genetic data, and source information.

AMR Strains

ATCC offers a wide array of clinically relevant AMR strains isolated from a variety of hospital- and community-acquired sources. These cultures are useful for studying the genetic variations between strain types, the in vitro evaluation of disinfectants and novel antimicrobials, and establishing the performance characteristics of molecular-based assays.

WHO Priority Pathogens

In response to the growing levels of antimicrobial resistance among pathogens, the World Health Organization prepared a list of priority pathogens in 2017 to help direct research and development efforts toward the production of novel drugs. This list is organized into critical (1), high (2), and medium (3) priority levels. To support these efforts, ATCC provides a growing collection of strains that represent these categories.
