UNSPSC 51201602: Brucella antigen

This classification denotes a vaccine against a genus of gram-negative, aerobic bacteria that causes brucellosis. Its cells are nonmotile coccobacilli and are animal parasites and pathogens. The bacterium is transmissible to humans through contact with infected dairy products or tissue.

UNSPSC 51201602 Brucella antigen is a Commodity code nominally describing diagnostic or immunological reagents in the microbiology testing family, but recent state and local activity under the code shows minimal relevant procurement volume. The Mississippi State Department of Health posted a sole source notice in July 2026 for Yellow Fever Vaccine from Sanofi Pasteur — a vaccine product that falls outside the Brucella antigen scope and suggests either misclassification of the procurement or inconsistent code assignment by the issuing health department. The notice itself does not describe a competitive solicitation but rather a sole source declaration with an objection period, meaning it does not represent an open bidding opportunity.

No other recent state and local opportunities appear under this Commodity code in the available data. The single posting presents a mismatch between the code's nominal scope — diagnostic antigens for brucellosis testing — and the actual procurement subject matter, signaling either administrative mistagging or extremely limited use of this code designation in state and local procurement. Firms monitoring Brucella antigen opportunities should expect low activity under this code and should verify code assignment when opportunities do surface, as the Mississippi posting demonstrates that state agencies may apply it to unrelated products.
