The role of IgE antibodies against respiratory syncytial virus has attracted attention for both human and bovine disease. To detect such antibodies, we have developed an enzyme-linked immunosorbent assay (ELISA) specific for bovine respiratory syncytial virus (BRSV). Firstly, anti-serum strongly positive for BRSV-specific IgE was produced by immunizing a levamisole-treated calf with BRSV. The presence and specificity of BRSV-specific IgE in this animal was confirmed with the Praunitz-Kustner (PK) technique. Potential interference in an ELISA by other BRSV-specific immunoglobulin isotypes was eliminated by preferential precipitation of serum samples with 27.5% saturated ammonium sulfate. The correlation between the PK and the ELISA assay was greater than 93% and the ELISA was found to be more specific than the PK. Indeed, in a pilot experimental infection study, the serum levels of BRSV-specific IgE were found to correlate with the symptom expression following repetitive live virus aerosolization. This may prove to be a useful rapid test to study both herd immunity and the potential pathogenic influence of IgE.
