Abstract Background Koi Herpesvirus KHV affects both juvenile and adult common carp and koi and is especially lethal to fry. The high mortalities caused by the disease have had a negative impact on the international koi trade. Different diagnostic techniques have been used to detect KHV including isolation of the virus in cell culture electron microscopy several PCR tests ELISA and in situ hybridisation. All of these methods are time consuming laborious and require specialised equipment. Results A rapid field diagnosis of KHV in common and koi carp was developed using loop-mediated isothermal amplification LAMP . The LAMP reaction rapidly amplified nucleic acid with high specificity and efficiency under isothermal conditions using a simple water bath. Two methods of extracting DNA from host tissue were compared extraction by boiling and by using a commercial extraction kit. A set of six primers - two inner primers two outer primers and two loop primers - was designed from a KHV amplicon. The reaction .
