Foot and Mouth Disease (FMD)


Foot-and-mouth disease (FMD) is a highly contagious viral disease. It can spread rapidly and affects both domesticated and wild ruminants, as well as pigs. FMD has an economically devastating impact on affected countries because trade barriers are imposed in countries where the disease occurs.

The FMDV genome encodes a single polyprotein that is cleaved during the translation. Mature structural and nonstructural viral protein derive after a cascade of further cleavages by viral proteases.

Vaccine produced according to the guidelines of the OIE are depleted of nonstructural proteins like 3ABC during purification steps. Antibody to 3ABC is generally accepted as the most reliable single indicator for viral replication.

Detection of anti-3ABC antibodies has been described upon challenge in animals with and without previous vaccination, confirming the potential of 3ABC as a marker for the surveillance of vaccinated populations.
