Problems solved by technology

However, the LAMP method used in the detection needs to add dyes after 1 hour to judge the results or use agarose gel electrophoresis for ultraviolet analysis and imaging. This has shortcomings such as aerosol pollution caused by opening the cover and lack of real-time monitoring of the reaction. make an accurate judgment

Abstract

The invention discloses an LAMP kit for Vibrio cholera in an aquatic product. The kit comprises a reaction buffer solution, specific primers for detecting the Vibrio cholera, a BstDNA polymerase, a Vibrio cholera DNA positive template and ultrapure water; and the specific primers for detecting the Vibrio cholera comprise a pair of inner primers FIP and BIP and a pair of outer primers F3 and B3. The kit has the characteristics of strong specificity, high sensitivity, simplicity and fastness, and can be used for real-time rapid and accurate detection of Vibrio cholera of a base.

Description

technical field [0001] The invention relates to the technical field of biological detection of aquatic products, in particular to a LAMP kit for vibrio cholerae in aquatic products. Background technique [0002] Cholera is a severe intestinal infectious disease caused by Vibrio cholera (VC). The disease has an acute onset, rapid spread, and wide coverage. It is an international quarantine infectious disease and is listed as one of the Class A infectious diseases in my country. , is one of the main foodborne pathogenic microorganisms, which always threatens and brings harm to human beings. At present, this bacterium is one of the pathogenic bacteria that must be inspected for most imported and exported aquatic products. [0003] At present, the method for detecting pathogenic microorganisms in food is mainly based on the traditional method (SN / T 1022-2010), that is, the separation and identification method. This method takes a long time, usually 5-7 days, and sometimes 10-15 ...
