Four-layer enzyme immunoassay (EIA) detection of differences in IgG, IgM and IgA antibody response to Aujeszky's disease virus in infected and vaccinated pigs.

Abstract

The use of the four-layer enzyme immunoassay (EIA) for the detection of IgG, IgM and IgA antibodies against Aujeszky's disease virus in blood and oropharyngeal swabs of infected and vaccinated pigs is described. Mean antibody titres obtained using the four-layer EIA were 6.1 and 3829 times higher compared with the indirect enzyme-linked immunosorbent assay… (More)
