摘要：

Large-scale monitoring of foot-and-mouth disease (FMD) in livestock is imperative in an FMD control program. Detection of antibodies against non-structural proteins (NSP) of FMD virus (FMDV) is one of the best tools to estimate the prevalence of past infection; availability of such a well-validated test is therefore essential. Using a FMDV 3B protein-specific monoclonal antibody, we have developed a new NSP antibody blocking ELISA (10H9 bELISA) and validated it on large panels of sera from different susceptible species. The diagnostic sensitivity of the ELISA was 95% with a specificity of 98%, similar to the values found using a commercial kit (PrioCHECK FMD NS test). The 10H9 bELISA can be used in a broad range of FMD susceptible species making it a very useful tool in monitoring the foot-and-mouth disease control programs by detection of virus circulation in the vaccinated populations.
