Detection of foot-and-mouth disease serotype O by ELISA using a monoclonal antibody.

An ELISA assay with monoclonal antibody (MELISA) was used to type serotype O of foot-and-mouth disease virus (FMDV). All FMDV serotype O reference strains were positive by MELISA, while other viruses such as FMDV serotypes Asia 1, C, A and classical swine fever virus, swine vesicular disease virus, and porcine reproductive and respiratory syndrome virus remained negative. Further, FMDV serotype O positive samples were able to be detected by MELISA. This assay may be particularly suitable for diagnosis of FMDV serotype O infection in field stations.
