The IDEXX CBPP Ab Test is a competitive ELISA (cELISA) based on a monoclonal anti-MmmSC antibody (named 117/5). It was developed by the CIRAD-EMVT (FAO world reference center for CBPP), as an alternative to the CFT for the OIE, and can be used for official CBPP control. This test is under evaluation by the Joint Division FAO/AIEA within the framework of a Coordinated Research Project (CRP).
