Development and evaluation of a Luminex multiplex serology assay to detect antibodies to bovine herpes virus 1, parainfluenza 3 virus, bovine viral diarrhoea virus, and bovine respiratory syncytial virus, with comparison to existing ELISA detection method
چکیده انگلیسی

Detection of circulating antibodies to bovine herpes virus 1 (BHV-1), parainfluenza 3 virus (PI3V), bovine viral diarrhoea virus (BVDV) and bovine respiratory syncytial virus (BRSV) using ELISA is widely used for veterinary diagnostics and surveillance. In this paper, the potential of a multiplex serology test based on Luminex technology, where all antibodies are simultaneously detected in a single assay was investigated. The performance of “in-house” separate ELISAs which use relatively crude lysates of cultured virus as capture antigens, was compared to the multiplex assay where the same antigens were covalently bound to the fluorescent beads used in the Luminex platform. A panel of field serum samples was tested by the multiplex assay in parallel with the separate routine ELISAs to provide a comparison between tests. The BHV-1 and PI3V components of the multiplex test showed similar sensitivities and specificities to the separate “in-house” ELISAs. The performance of the BVDV and BRSV components was less successful and was attributed to relatively low signal strength for these antigens, leading to higher assay variability and a reduced ability to distinguish positive and negative samples compared to the “in-house” ELISAs. The results illustrated that antigens commonly used successfully in ELISAs cannot always be transferred for use in alternative assay systems. The use of recombinant BVDV E2 protein was investigated and was shown to lead to an appreciable increase in signal strength compared to the use of crude BVDV antigen in the Luminex system.
