Problems solved by technology

[0004] In the past, there were mainly three methods for detecting IHHNV in prawns: 1. Electron microscope method, which is costly, time-consuming, low sensitivity, and not suitable for on-site detection; 2. Gene probe method, which is costly and complicated to operate; 3. Polymerase chain method Reaction method (PCR method), which is faster and more sensitive than the previous two methods, but requires an expensive PCR instrument

Abstract

This invention provides a reagent box for testing IHHNV of prawns with RAM including a DNA pick up reagent, a crossbreed solution, a probe capture reagent, a washing liquid, a connecting- liquor, a RAM reaction liquor, a color developing reagent and especially a marker probe for testing IHHNV. A method for testing IHHNA with the reagent box is provided, which has the same high flexibility as the PCR test method but not need expensive PCR instrument, yet only cheap constant-temperature metal bath or water bath is enough.

Description

technical field [0001] The present invention relates to a kit for detecting infectious subcutaneous and hematopoietic necrosis virus (IHHNV) of prawns by isothermal branch amplification (Isothermal Ramification Amplification, referred to as RAM), and further relates to the rapid detection of infectious subcutaneous and hematopoietic necrosis virus (IHHNV) of prawns using the kit. Methods of hematopoietic necrosis virus. Background technique [0002] Shrimp aquaculture is the pillar industry of marine aquaculture in my country. In 1993, the outbreak of aquaculture prawn diseases in my country brought serious economic losses to the entire prawn aquaculture industry. Related industries such as shrimp processing and foreign trade exports were also seriously affected. In recent years, my country has introduced new species of prawns such as Litopenaeus v vannamei (commonly known as Litopenaeus vannamei) and Litopenaeus stylirostris (commonly known as blue prawn), which are native ...
