The NARSA Strain Repository is transitioning to BEI Resources, NIAID?s centralized research reagent repository in May 2014. Due to this transition, Eurofins will no longer be registering users after March 14th, 2014. Eurofins will no longer be taking orders on May 23rd, 2014 All orders after May 23rd, 2014, should be made through BEI Resources.

Registration for the BEI Resources program can be found at this link below. NARSA Strain requestors will need to register for ?Level 2? for continued access to the NARSA Strains. ** Please note if you are an existing NARSA registrant, BEI Resources will contact you after the Annual Meeting with specific registration instructions and paperwork to facilitate your registration.

Once registered with BEI Resources, researchers will have access to the full BEI Resources catalog (within the respective Biosafety Level). The catalog has over 12,000 research reagents representing more than 400 Genus and Species focusing on NIAID?s Category A, B and C priority pathogen list and Emerging Infections.

Once registered with BEI Resources, ALL investigators will receive FREE shipping and handling on orders placed through BEI Resources.

Please feel free to contact BEI Resources by email: or by phone: Toll-free telephone number: (800) 359-7370 (8:30 AM to 4:30 PM Eastern Time) with any questions or concerns.


Providing Critically Needed Isolates


Welcome to the Website for the Network on Antimicrobial Resistance in Staphylococcus aureus (NARSA). The NARSA program is funded by the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH) and is designed to support and facilitate critical research efforts among clinical and basic scientists from the academic, industrial, and public health sectors regarding staphylococcal infections and disease.


The NARSA program has established an infrastructure that supports cross fertilization of biological, medical, and epidemiological research directed towards understanding antimicrobial resistance and other medically relevant genetic and physiological characteristics among staphylococci.


This infrastructure includes:


         A continuously expanding, centralized Repository of strains exhibiting reduced susceptibility to vancomycin and other characteristics of research and clinical importance and interest.


         A database of microbiologic and clinical information that accompanies the Repository of strains.


         A Website that provides Registered Users with:

1)      access to the NARSA Repository database.

2)      ability to peruse the isolate inventory catalog and order available isolates.

3)      links to other key sources of information regarding staphylococcal research.

4)      a forum for investigators to share and relate their findings and knowledge about recent advances in staphylococcal research.

5)      access to contact information and research interests of other Network participants.


In order to gain access to the isolates available in NARSA's Repository, to view the data collected and maintained for these isolates, and to interact with other Network participants, you must Register with the program. For additional information or questions concerning NARSA, please see the Program Synopsis or Contact Us.
