ABSTRACT
A method for separation of spring viraemia of carp virus (SVCV) from large-volume samples using immunomagnetic beads (IMBs) coated with a polyclonal antibody against SVCV was developed. The optimum amount of IMBs was 2 mg in 100 mL. After IMB treatment, the detection limit of SVCV in reverse transcription quantitative PCR (RT-qPCR) was 103 times the 50% tissue culture infectious dose per mL in 100-mL samples. The concentration of viral RNA extracted from SVCV that had been separated using IMBs was 5.18 × 103-fold higher than that of the unseparated SVCV. When fish samples were tested, the concordance rates of the IMBs/RT-qPCR and RT-qPCR were 100% and 67.5%, respectively.
