Description

Primer for gene amplification of pathogenic microorganism, method for detecting pathogenic microorganism using same, and detection kit {PCR PRIMERS FOR AMPLIFYING THE GENE OF PATHOGENIC MICROORGANISM, AND METHOD AND TEST KIT FOR DETECTING PATHOGENIC MICROORGANISM BY USING THE SAME}

According to the present invention, PCR primer pairs capable of amplifying specific genes of nine pathogenic microorganisms, and using the same, perform a multiplex-polymerase chain reaction (M-PCR) to quickly and accurately identify pathogenic microorganisms causing food poisoning. The present invention relates to a pathogenic microorganism detection method and a detection kit.

Despite the development of science and technology, it is still difficult to completely prevent food poisoning. Food poisoning is food poisoning caused by natural poisoning (blowfish poison, mushroom poison, etc.) based on the cause; Food poisoning due to food decay; And food poisoning by incorporation or reproduction of bacteria in food. Among these food poisonings, food poisoning caused by natural poisoning can be easily prevented by avoiding the ingestion of foods that cause the food poisoning. Relatively easy. However, in the case of food poisoning caused by bacteria, that is, bacterial food poisoning, food poisoning is most difficult to prevent because it is generally not observed by the naked eye and is difficult to detect by professional methods. can do.

Recently, as food facilities, such as restaurants, order delivery, food centers, and fast food restaurants, are being used in large quantities, and many consumers use them, there is a risk that many people will get food poisoning in a short time when bacterial food poisoning occurs in these facilities. And because bacterial food poisoning is severe, such as severe vomiting, diarrhea, abdominal pain, and high fever, the occurrence of group food poisoning is a significant problem for both food suppliers and consumers. In addition, these food poisoning causative bacteria produce toxic substances such as endotoxins in the body of infected people, so the treatment should be performed after infection, and in many cases, the treatment is difficult. Especially, very serious such as hemorrhagic enteritis such as pathogenic E. coli O157: H7 Symptoms may be severe and lead to death in severe cases. Therefore, it can be said that there is an urgent need for early detection and prevention of the causative agent of pathogenic food poisoning.

As a method of detecting and confirming the causative agent of bacterial food poisoning, the collected sample is cultured using a selective medium, the colonies formed on the medium are visually observed, or other detection and confirmation means are used. In the test method using a polymerase chain reaction (PCR) has been developed and used.

Polymerase Chain Reaction (PCR) is a simple and convenient way to exponentially amplify DNA sequences of specific regions with very small amounts of DNA. Two different primers in the opposite direction and Taq DNA polymerase, which are functionally stable at high temperatures, are used in three different temperature cycles: denaturation step, annealing step, and extension step. Repeatedly amplify specific DNA. The detection method of pathogenic microorganisms using PCR is amplified by PCR reaction using primers that recognize specific genes of microorganisms to be detected and confirmed by electrophoresis, etc. Pathogenic microorganisms can also be detected.

As a prior art related to a pathogenic microorganism detection method using PCR, Patent Publication No. 1999-65107 discloses four specific genes (2 verotoxins) possessed by Escherichia coli (O157: H7) using a polymerase chain reaction method. A method for simultaneously detecting multiple genes (multiplex-PCR) capable of detecting barrier-associated pathogens and enzyme specific genes) is described. In addition, Japanese Patent Laid-Open No. 1999-88425 discloses oligonucleotides that selectively hybridize with the Verotoxin gene of EHEC or VTEC or the O antigen synthesis region gene of Escherichia coli O157, and perform PCR using this oligonucleotide as a primer. It describes a method for selectively detecting the bacteria producing E. coli and E. coli capable of producing vero toxin.
