Problems solved by technology

This technology has been preliminarily studied in the detection of food-borne pathogens, but all of them use a single detection, which takes a long time and costs high
The dual LAMP system for simultaneous detection of Vibrio parahaemolyticus and Vibrio cholerae has not been reported
If a multiple LAMP system is used, due to the existence of multiple pairs of primers, the interference between primers and the mismatch between primers and templates will cause problems such as decreased sensitivity and increased non-specific amplification reactions.

Abstract

The invention discloses a double LAMP (loop-mediated isothermal amplification) detection primer and kit for Vibrio parahaemolyticus and Vibrio cholera in aquatic products, comprising three pairs of Vibrio cholera LAMP primers and three pairs of Vibrio parahaemolyticus LAMP primers. Inter-primer interference is low, nonspecific amplification reactions are few, detection sensitivity and specificity are guaranteed, detection speed is increased, and detection cost is lowered.

Description

technical field [0001] The invention relates to the technical field of biological detection of aquatic products, in particular to a dual LAMP detection primer and a kit for Vibrio parahaemolyticus and Vibrio cholerae in aquatic products. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to food safety, which has become a major worldwide public problem, and foodborne diseases caused by pathogenic microorganisms are one of the most important factors affecting food safety. Vibrio parahaemolyticus and Vibrio cholerae are recognized worldwide as two important intestinal pathogens. The former widely exists in the marine environment and is one of the main pathogenic bacteria threatening the mariculture industry. It can infect fish, shrimp and shellfish, etc., cause shrimp red body disease, fish skin ulcers and other diseases, and cause major economic losses to the aquaculture industry. . Humans can cause food poiso...
