Detection of Antibodies Against Foot-and-Mouth Disease Virus Serotypes A, O and Asia-1 by ELISA in Strip-Dried Samples from Vaccinated Bovines

Antibodies against foot-and-mouth disease virus serotypes A, O and Asia-1 were detected by ELISA in liquid and strip-dried samples from vaccinated bovines. The results showed high concordance of the results in both types of serum samples (coefficient of correlation varied from 0.89 to 0.96). Stability studies showed that anti-foot-and-mouth disease virus antibodies can be detected in strip-dried serum samples stored at different temperatures on a level of that in native samples. Preliminary study in strip-dried whole blood samples demonstrated good potential of this sample pretreatment procedure for the following anti-foot-and-mouth virus antibodies testing.
