Development of a rapid cyprinid herpesvirus 2 detection method by loop-mediated isothermal amplification

摘要

Significance and Impact of the Study: Herpesviral haematopoietic necrosis, caused by cyprinid herpesvirus 2 (CyHV-2), is a severe disease of goldfish and Prussian carp associated with high mortality. We developed a loop-mediated isothermal amplification (LAMP) assay to detect CyHV-2 at relatively low plasmid DNA copy levels. The results show that the LAMP assay has a number of advantages (simple, sensitive, rapid and specific) over the conventional polymerase chain reaction and can be applied in the laboratory and field. Particularly, the method is highly applicable to facilitate surveillance and early diagnosis of CyHV-2
