Problems solved by technology

Some of these detection methods have high technical requirements, long detection time, troublesome preparation of materials required, high cost, and low sensitivity and low specificity of some methods. Therefore, it is very difficult for the majority of shrimp farmers to master key technologies, and it is difficult to popularize , limiting the application and development of these technologies

Abstract

The present invention is prawn white spot syndrome virus gene diagnosing kit and its usage. The kit and its usage is designed based on two pairs of primers for the conservation sequence of prawn white spot syndrome virus gene. By means of PCR technology, the present invention detects qualitatively the specific DNA nucleic acid segment of prawn white spot syndrome virus fast, simply, specifically and sensitively. The present invention may be used in the tracing detection of different stages of prawn cultivation and environment monitoring.

Description

technical field [0001] The invention relates to a diagnostic kit and a detection method for diseases of aquatic economic animals, and mainly relates to a kit and a detection method for genetic diagnosis of white spot syndrome virus (WSSV, White Spot Syndrome Virus) of prawns. Background technique [0002] Since the 1990s, shrimp diseases have exploded in many countries and regions in Asia, and the production of prawn farming has dropped sharply, causing major economic losses. Shrimp diseases, especially shrimp virus diseases, have seriously hindered the sustainable development of the shrimp farming industry. Among the many shrimp viruses, the white spot syndrome virus (WSSV) is the most serious, and it is the number one killer of the shrimp farming industry. The research on WSSV is also a hot spot in the research of aquaculture diseases in recent years. At present, there is no specific treatment method for shrimp virus disease. The most effective preventive measure is to p...
