Multidrug-Resistant Reference Strains

Multidrug-resistant (MDR) strains have been attributed to numerous nosocomial infections worldwide, resulting in increased morbidity, mortality, and health-care expense. To support the field of MDR research, ATCC has acquired and authenticated various clinical and environmental isolates exhibiting resistance to numerous antimicrobial agents.

Carbapenem-Resistant Enterobacteriaceae (CRE)

ATCC® Carbapenem-resistant Enterobacteriaceae (CRE) strains are clinical isolates confirmed to carry either the blaKPC or blaNDM gene, conferring resistance to carbapenem antibiotics. Each strain demonstrates multidrug-resistance to as many as 36 representative antibiotics.

These strains are ideal for the development, verification, and evaluation of:

  • Rapid detection methods
  • Innovative therapeutic techniques
  • Novel antibiotics
  • Updated sterility protocols

ATCC hopes that with your diligent research and our authenticated strains, we can stop the spread of superbugs together!

Methicillin Resistant Staphylococcus aureus (MRSA)

ATCC® Methicillin-resistant Staphylococcus aureus (MRSA) strains are confirmed to carry the mecA gene, which confers resistance to methicillin. These cultures are useful for studying the genetic variations between MRSA SCCmec types, the in vitro evaluation of disinfectants and novel antibiotics, and establishing the performance characteristics of molecular-based assays.
