Abstract

The invention belongs to the technical field of reproduction, and particularly relates to a CyHV-2 (cyprinid herpesvirus 2) specificity PCR (polymerase chain reaction) detection kit and a detection method. The CyHV-2 specificity PCR detection kit comprises 2*reaction mixing buffer solutions (1.0mL), preferably designed upstream and downstream primers, Taq DNA (deoxyribonucleic acid) polymerase, positive contrast liquid, negative contrast liquid and ddH2O. The invention overcomes defects of the existing CyHV-2 detection method, and provides the novel PCR fast detection kit and the detection method. The CyHV-2 specificity PCR detection kit and the detection method have the advantages that the clinical diagnosis of CyHV-2 is feasible, in addition, the advantages of high speed, accuracy and specificity are realized, the clinical diagnosis requirements are met, and convenient conditions are provided for CyHV-2 detection.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a genetic detection reagent and detection method for crucian carp herpes virus type 2, which is suitable for epidemiological monitoring of crucian carp carp herpes virus type 2, detection of carp herpes virus type 2 and genetic engineering technology and other fields. Background technique [0002] Cyprinid herpesvirus 2 (CyHV-2), also known as Herpesviral haematopoietic necrosis virus (HVHNV) or Goldfish haematopoietic necrosis virus (GFHNV). The virus was isolated and identified from goldfish cultured in Japan for the first time in 1992-1993, and it was also the first report of the disease. It once caused huge economic losses to the goldfish farming industry in Japan, with a mortality rate as high as 100%. The virus first appeared in the Jiangsu area of ​​my country in 2009. The blood of dying fish would flow out along the gill filaments. Fishermen called it "gill bleeding". ...
