The Centers for Disease Control and Prevention (CDC) is seeking to award a sole source contract for antimicrobial resistance testing supplies, specifically Sensititre™ broth microdilution testing products, from ThermoFisher Scientific. This procurement is essential for the National Antimicrobial Resistance Monitoring System (NARMS), which has utilized these proprietary materials since 1996 to ensure a standardized approach to monitoring enteric bacteria resistance. The unique nature of these supplies necessitates this sole source approach, as alternatives would require significant investments in new equipment and validation processes, potentially disrupting critical surveillance efforts. Interested parties may respond within 15 days to express their interest, with proposals directed to contract specialist Ashley Williams at dal3@cdc.gov.
