[ Method] Primers and corresponding TaqMan probe were designed based on the conserved sequence of Koi herpes virus （KHV） pol-ymerase gene （Sph） to establish a rapid and effective fluorescence quantitative PCR method for Koi herpes virus detection. The cell cultures were detected by using the established fluorescence quantitative PCR assay, and the results were com- pared with that of conventional PCR. [ Result] The sensitivity of fluorescence quantitative PCR was higher than that of conventional PCR. The minimum copy num- ber that could be detected was 1.6 - 102 copies/p.1. The established method was adopted for sample detection, and a reliable diagnostic result could be obtained within 4 h. [Conclusion] The established method is rapid, sensitive, specific and repeatable, which is conducive to the rapid detection of Koi herpes virus.
