Investigation on the diagnostic sensitivity of molecular tools used for detection of koi herpesvirus.

Previous and new PCRs for KHV detection were compared by estimation of their sensitivity in recognizing KHV DNA in plasmids, cell culture extracted KHV DNA and total DNA obtained from field tissue samples. A modified real-time PCR (Gilad et al., 2004), combined with an internal control system (IC2, Hoffmann et al.
