An accelerated solid-phase enzyme-immunoassay has been developed which
permits identification of antigens and antibodies to them within 30-4
0 min, even directly at the site of specimen collection. The method wa
s tested on the models of foot-and-mouth disease virus, vesicular dise
ase of swine, vesicular exanthema of swine, Aujeszky's disease, leukem
ia, and coronavirus infection of cattle.
