Oligonucleotide probe set for dectecting food-borne pathogens and microarray containing the probe set}

The present invention relates to an oligonucleotide probe set for detecting food poisoning bacteria, a microarray and a kit including the probe set.

Food poisoning bacteria are causing major problems in human health around the world, and there is a need for rapid detection of food poisoning bacteria in the fields of food industry, public health promotion and microbial terrorism. The major food poisoning bacteria that cause disease in humans are: Bacillus cereus ), Listeria monocytogenes , Staphylococcus aureus), Clostridium botulinum (Clostridium botulinum ), Clostridium perfringens , Campylobacter jejuni ), Vibrio parahaemoritis ( Vibrio) parahaemolyticus ), Yersinia enterocolitica , Escherichia coli ) O157: H7 and Salmonella enterica serova typhimurium enterica serovar Typhimurium). Detection of such food poisoning bacteria is very important in human health and food industry, and sensitivity, detection time and specificity are the most important requirements in detecting food poisoning. Known biochemical methods of food poisoning bacteria generally require 2-3 days, and it is difficult to detect multiple pathogens in one experiment.

Although some methods of detecting food poisoning bacteria using DNA have been reported, PCR (polymerase chain reaction) is the most commonly used method. However, PCR has a problem in detecting multiple food poisoning bacteria because of the limited number of primers used. In addition, there is a possibility of showing false-positive or false-negative by similarity or diversity of DNA sequences among similar genus strains. Microarray experiments centered on DNA sequences have been used for experiments such as gene expression, genotyping and single-nucleotide polymorphism (Chizhikov et al. 2002. J. Clin. Microbiol. 40). : 2398-2407). In addition, the microarray test method has been proposed as a new method for detecting food poisoning bacteria because of the potential for detecting a plurality of food poisoning bacteria in one experiment (Al-khaldi et al. 2002. J. AOAC Int. 85: 906-910).

Recently, cDNA and oligonucleotide microarray techniques have been applied to the analysis of pathogenic microorganisms (Burton et al. 2005. Molecular and Cellular Probes. 19: 349-357), and one chip can detect four food poisoning bacteria. Studies have been reported (Sergeev et al. 2004. Biosensors and Bioelectronics. 20: 684-698). Probes produced in these previous studies were constructed from microbial flagelline genes or virulence genes (including pathogenic genes), 16S rRNA or 23S rRNA sequences. However, these target genes share their sequence among microorganisms of the same genus, which is likely to result in cross-hybridization. In addition, in these studies PCR is performed prior to hybridization, which is limited to the number of available probes, which makes it difficult to detect a large number of pathogens (Chizhikov et al. 2001. Appl. Environ. Microbiol. 67: 3258). -3263).

As of January 2006, genomic sequences for more than 270 microorganisms have been published in the National Center for Biotechnology information (NCBI, http://www.ncbi.nih.gov/genomes/lproks.cgi ). Genomic sequencing work for food poisoning bacteria is finished or in progress.

Korean Patent Registration No. 10-611056 discloses an oligonucleotide microchip for detecting pathogenic microorganisms and a pathogenic microorganism detection method using the same. Korean Patent Registration No. 10-671501 discloses a food poisoning primer and a bacterial food poisoning detection method using the same.

These food poisoning bacteria are known to be difficult to detect because they have high similarity in genomic DNA sequence with other microorganisms of Enterobacteria. Recently 10 probes constructed from the gyrB gene were evaluated to identify Escherichia coli , Shigella and Salmonella (Kakinuma et al. 2003. Biotechnology and Bioengineering. 83: 721-728). However, some probes showed reaction with other microorganisms, and thus did not show enough results to distinguish them from microorganisms within Enterobacteriae. Salmonella in the present invention enterica serovar Typhimurium, Salmonella enterica serovar Typhi, Escherichia coli O157: H7 with Yersinia Probes specific to enterocolitica were presented, and each of the ten probes was confirmed to be specific to each food poisoning bacterium as shown in FIG. 3. Salmonella enterica serovar Typhimurium was confirmed to specifically react to 10 selected probes as shown in Figure 3 (A, B, C).

Of the 10 Salmonella enterica serovar Typhimurium-specific probes, four probes were found to react specifically to serovars belonging to Salmonella subspecies I, which are known to cause disease in mammals or birds (Fig. 7, Salmonella). serovar Choleraesuis, Enteritidis, Pullorum, Gallinarum, Paratyphi C and Paratyphi B). If Salmonella in that belonging to Salmonella subspecies I has been confirmed that it does not react with any probe. In the case of Salmonella serovar Typhi specific probes, Salmonella serovar Typhi ATCC 33459 and ATCC 6539 reacted specifically as shown in FIGS. 3 and 7. Salmonella serovar Paratyphi A is a strain that is known to cause disease in humans, and it was confirmed that it reacts with three of serovar Typhi-specific probes, which has been reported as serovar Typhi and Paratyphi A. Genetic traits were confirmed to be close (data not shown). Yersinia enterocolitica ATCC 23715 and Escherichia In the case of coli 0157: H7 ATCC 43894, as shown in FIG.
