Oligonucleotides for detecting Salmonella species and detection process using the same

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to detection of Salmonella species causative of food poisoning in clinical tests or food inspections.
2. Discussion of the Related Art
The specimens tested for food poisoning are collected from the materials in the surroundings of patients, such as patient's excreta or feces, food and wiping materials. Detection and identification of Salmonella species with these specimens conventionally require to perform enrichment culture, confirmation culture and antigen determination (serotyping). The bacteria of Salmonella species are divided into many serotypes, and complete serotyping requires as many as 100 antisera and much experience, thereby making it difficult to carry out the detection of Salmonella species in an ordinary laboratory. Also, each culture step takes 18 to 24 hours, and as a whole it takes about 3 days from enrichment culture to serotyping. Thus, the method described above is poor in rapidity. Furthermore, confirmation culture involves inoculation of bacteria to TSI agar, SIM medium, VP-MR medium and lysine decarboxylation test medium, and subsequent overnight culture at 37.degree. C.; the serotyping needs the use of commercially available set of antisera against O and H antigens; these operations make the detection tedious and costly.
In recent years, DNA probing or hybridization using oligonucleotides has been tried for the detection of bacteria. However, when hybridization of a labeled oligonucleotide probe is carried out on a membrane or on other supports, the sensitivity depends on the number of organisms available for the detection. Therefore, without the above-described cultures as pretreatments, it is difficult to achieve high sensitivity and high selectivity in detecting the bacteria of interest.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide synthetic oligonucleotides used as primers for PCR to amplify the enterotoxin genes specific to Salmonella species.
It is another object of the present invention to provide a simple, rapid and highly sensitive process for detecting the enterotoxin genes specific to Salmonella species for quarantine inspection of food poisoning and clinical laboratory tests for diarrheal patients.

DETAILED DESCRIPTION OF THE INVENTION
The main feature of the present invention resides in a process of selectively amplifying a DNA sequence contained in an enterotoxin gene of Salmonella species causative of food poisoning by the PCR technique, using oligonucleotide primers chemically synthesized to specifically hybridize with the gene; and then detecting the amplified gene sequence.
According to the present invention, a high selectivity and sensitivity can be achieved in the detection of enterotoxic Salmonella species using the PCR technique.
Because of high sensitivity, the detection of the present invention does not require a large amount of specimens nor complicated pretreatments of specimens. Also, the present method can significantly reduce the time needed for the detection because of short reaction time, simple equipment, and easy operation. Actually, in the examples of the present application, it took only about 3.5 hours for the entire detection, i.e., 3 hours for amplification and 0.5 hours for detection.
By the use of agarose gel electrophoresis and nucleic acid staining with ethidium bromide in the detection of the present invention, a label-free oligonucleotide probe can be used and the length of DNA fragment can be confirmed, thereby making the detection highly reliable.
The present method can detect all the Salmonella species causative of food poisoning, regardless of species and serotypes. Thus, as compared with the method for individually detecting different species and serotypes, the present invention can provide extremely useful reagents and methods for the detection of Salmonella species.
Oligonucleotides
When the stn gene, an enterotoxin gene of Salmonella typhimurium, is targeted, the following oligonucleotide primers that are complementary to the gene are chemically synthesized: Oligonucleotides of SEQ ID NOS: 1 to 6 and oligonucleotides complementary thereto.
When the inv A gene, another enterotoxin gene of Salmonella typhimurium, is targeted, the following oligonucleotide primers that are complementary to the gene are chemically synthesized: Oligonucleotides of SEQ ID NOS: 7 to 9 and oligonucleotides complementary thereto.
Amplification of Gene Sequence by PCR
For amplification of a region of a target gene in the present invention, the PCR developed by Saiki et al. �Science 230, 1350 (1985)! is employed.
Specifically, two oligonucleotide primers that flank a nucleotide sequence of interest, i.e., the enterotoxin genes of Salmonella species in the present invention, are synthesized. One of the oligonucleotide primers selectively hybridizes to the (+)-strand of a target gene, and the other hybridizes to the (-)-strand of the gene. Then, both the oligonucleotides serve as primers of template dependent DNA polymerization. Each of the single strands of the target DNA resulting from heat denaturation of the double stranded DNA in specimens serves as the template. The duplexes formed by the DNA polymerization reaction are then denatured to separate the primer extension products from the templates. Then, the primer extension products themselves serve as the templates for the next DNA polymerization reaction. The cycle of denaturation, primer annealing (hybridization of primers to the template DNAs) and primer extension reaction is repeated until the region flanked by the two primers is amplified to a detectable level.
Specimens applicable to the PCR in the present invention may include clinical samples, such as feces, urine, blood, tissue homogenate, and food samples. A specimen for PCR should be pre-treated to release the nucleic acid components from the bacterial cells present therein. Since PCR can proceed with only several to several tens of nucleic acid molecules, a test solution containing an adequate amount of nucleic acid can be prepared simply by treating a specimen for a short time with a lyric enzyme, a surfactant or an alkali.
The oligonucleotides used as primers in the present invention may be either synthetic or natural, and in view of selectivity, detection sensitivity and reproducibility, their length is not less than 10 bases, preferably not less than 15 bases. It is not necessary to label the primers for detection.
The region to be amplified in a target gene, i.e., the stn gene or the inv A gene of Salmonella species, is 50 to 2000 bp in length, preferably 100 to 1000 bp.
As the agent for polymerization, a thermostable DNA polymerase is used. The sources from which the enzyme is derived are not particularly limited as long as the enzyme retains its activity at temperatures of from 90.degree. to 95.degree. C. The denaturation is carried out at a temperature of from 90.degree. to 95.degree. C.; the primer annealing, from 37.degree. to 65.degree. C.; and the polymerization reaction, from 50.degree. to 75.degree. C. The cycle of denaturation, primer annealing, and polymerization is repeated 20 to 42 times.
The presence or absence and the length of the amplified DNA fragment can be detected by subjecting the reaction solution to agarose gel electrophoresis after the completion of PCR. Other types of electrophoresis and chromatography can also be used for the detection.
The presence of a nucleotide sequence of a Salmonella enterotoxin gene in a specimen indicates that the specimen is positive for the Salmonella species.
In the detection of a target DNA on a membrane or other supports, one of the oligonucleotide primers (SEQ ID NOS: 1 to 9) may be used as a probe. In this case, it is preferable to label the oligonucleotide.
The following examples are offered by way of illustration and are not intended to limit the invention in any manner.
EXAMPLES
Example 1
Detection of the stn Gene of Salmonella Species
(Salmonella typhimurium)
�Experiment 1!
Preparation of specimens
The 174 strains of Salmonella species listed in Tables 1-1 to 1-7 were obtained from specimens in food poisoning cases, e.g., diarrheal feces and vomit of patients, and causative food of food poisoning. Each strain was inoculated to a Brain Heart Infusion medium (manufactured by BBL), and subjected to overnight shaking culture at 37.degree. C. under aerobic conditions. Each culture broth was diluted with 10 mM Tris-HCl buffer, pH 7.5 (hereinafter referred to as TE buffer), and heated at 95.degree. C. for 10 minutes, and subjected to centrifugation. The supernatant was used as a specimen.
Synthesis of Primers
As the primers for amplifying the stn gene of Salmonella typhimurium, the oligonucleotide sequences set forth in the Sequence Listing (SEQ ID NOS: 1 to 6) were selected based upon the known nucleotide sequence of the stn gene (Chopra, A. K. et al., Microbial Pathogenesis 16, 85-98(1994)). The oligonucleotide primers were chemically synthesized by the .beta.-cyanoethylphosphoamidite method using a Cyclone Plus DNA synthesizer (manufactured by MilliGen/Bioresearch). The synthesized oligonucleotides were purified by high performance liquid chromatography using a C18 reversed-phase column.
PCR
To 3 .mu.l of the specimen as prepared above, 16.05 .mu.l of sterile distilled water, 3 .mu.l of 10.times. reaction buffer, 4.8 .mu.l of dNTP solution, 1.5 .mu.l each of primer (A) and primer (B), and 0.15 .mu.l of a thermostable DNA polymerase were added to make 30 .mu.l of a reaction mixture. On the reaction mixture, 50 .mu.l of mineral oil (produced by SIGMA) was overlaid.
Reaction Mixture for PCR
10.times. reaction buffer: 500 mM KCl, 100 mM Tris-HCl, pH 8.3, 15 mM MgCl.sub.2, 0.1% (w/v) gelatin.
dNTP solution: A mixture of dATP, dCTP, dGTP and dTTP, each having a final concentration of 1.25 mM.
Primers (A) and (B): Aqueous solution of the above-described chemically synthesized and purified oligonucleotides (concentration, 3.75 OD/ml).
The oligonucleotide primers synthesized were used in the following combinations:
______________________________________Primer (A) Primer (B)______________________________________SEQ ID NO:1 SEQ ID NO:4SEQ ID NO:2 SEQ ID NO:5SEQ ID NO:3 SEQ ID NO:6______________________________________
Thermostable DNA polymerase: Taq DNA polymerase (5 unit/ml; produced by Perkin Elmer Cetus).
Reaction conditions
Denaturation: 94.degree. C., 1 minute.
Annealing: 55.degree. C., 1 minute.
Elongation: 72.degree. C., 1 minute.
The cycle of denaturation, primer annealing and elongation (5.7 minutes) was repeated 35 times (entire time, about 3 hours). This procedure was performed using a DNA thermal cycler (produced by Perkin Elmer Cetus) in which the above reaction conditions had been programmed.
Detection
Agarose Gel Electrophoresis
Agarose gel electrophoresis was employed to detect the amplified DNA.
The reaction mixture after the PCR thermal cycling was applied to a 3% (w/v) agarose gel and separated by electrophoresis at a constant voltage of 100V for 30 minutes. A 0.5 .mu.g/ml ethidium bromide solution was used as a fluorescent dye to detect the DNA bands. Operation procedures and other conditions employed are described by Maniatis et al. (Molecular Cloning, 2nd edition (1989)). In addition to the reaction mixture, a molecular weight marker was also electrophoresed concurrently. The length of the DNA fragment was calculated by comparing the relative mobilities.
Results
The nucleotide sequence of the stn gene of Salmonella typhimurium is known. Since the complementary sequence to part of the hyd G gene, or the hyd H gene), an essential enzyme for Salmonella species, the DNA sequence of the stn gene is thought to be common to all Salmonella species. The length of the nucleotide fragment amplified by PCR using the oligonucleotide primers of the present invention can easily be estimated.
Specifically, when oligonucleotides of SEQ ID NO: 1 and SEQ ID NO: 4 are used in combination, the length of the DNA fragment amplified is estimated to be 260 bp. Similarly, the combination of SEQ ID NO: 2 and SEQ ID NO: 5 and that of SEQ ID NO: 3 and SEQ ID NO: 6 amplify DNA fragment of 224 bp and that of 264 bp, respectively. When the estimation accorded with the length of the DNA fragment actually amplified, the combination of primers was evaluated to accurately amplify the target nucleotide sequence in the stn gene and marked with "+" as shown in Tables 1-1 to 1-7, whereas the combination of primers that failed to amplify the target nucleotide sequence was marked with "-" in the Tables. As obvious from Tables 1-1 to 1-7, the stn gene was accurately amplified in all the Salmonella species tested.
�Experiment 2!
To determine whether the results obtained in Experiment 1 are specific to Salmonella species having the stn gene, the genes of clinically important enterotoxic bacteria other than Salmonella species were examined with the oligonucleotide primers of the present invention. In particular, differentiation between Salmonella species and Citrobacter species, which is difficult by conventional methods, was carefully examined.
Preparation of Specimens
The test strains are listed in Tables 2-1 to 2-12. The same procedure as used in Experiment 1 was carried out, except for the following changes in conditions: Clostridium perfringens, Campylobacter jejuni, Campylobacter coli, Bacteroides flagilis, Bacteroides vulgatus, Lactobacillus acidophilus, and Bifidobacterium adolescentis were cultured at 37.degree. C. under anaerobic conditions, while Neisseria gonorrhoeae and Neisseria meningitidis were cultured in the presence of 3-10% CO.sub.2. Human placenta DNA, at a concentration of 1 .mu.g/ml, was also subjected to PCR in the same manner as above.
Results
The results are shown in Tables 2-1 to 2-12. The combinations of the oligonucleotide primers of the present invention did not amplify any DNA fragments of other bacterial strains than Salmonella species nor human placenta DNA. It is of particular importance that though there were a very few exceptions, the combinations of the primers of the present invention did not amplify DNAs of Citrobacter species, which are closely akin to and hardly differentiated from Salmonella species, with 93% or higher accuracy. It can therefore be concluded that the oligonucleotide primers of the present invention react with the DNAs of Salmonella species with high selectivity, thereby giving a highly reliable results.
The agarose gel electrophoresis used in the above experiments can differentiate DNA fragments which are different in length by 5-10 bp for DNA fragments of not less than 100 bp and by 10-20 for DNA fragments of 100-500 bp. In addition, the use of other gel material such as acrylamide can improve the precision of the measurement of the length of DNA fragment, thereby further increasing the reliability of the specific detection of the stn gene.
Example 2
Detection of the inv A gene of Salmonella species
�Experiment 1!
Preparation of Specimens
The test specimens were prepared as described in Example 1.
Synthesis of Primers
As primers for amplifying the inv A gene of Salmonella species, the oligonucleotides of SEQ ID NOS: 7 to 9 set forth in the Sequence Listing were selected based upon the known nucleotide sequence of the inv A gene (Galan, J. E. et al., J. Bacteriol. 174, 4338-4349 (1992)). The oligonucleotide primers were chemically synthesized and purified in the same way as described in Example 1.
PCR
The same procedures and conditions as those in Example 1 were used except that the following combinations of primers were employed:
______________________________________Primer (A) Primer (B)______________________________________SEQ ID NO:7 SEQ ID NO:8SEQ ID NO:7 SEQ ID NO:9______________________________________
Detection
The same procedures as in Example 1 were followed.
Results
The nucleotide sequence of the inv A gene of Salmonella species is known. Therefore, the length of the DNA fragment amplified by PCR using the oligonucleotide primers of the present invention can easily be estimated.
When oligonucleotides of SEQ ID NO: 7 and SEQ ID NO: 8 are used in combination, the length of the DNA fragment amplified is estimated to be 378 bp. Similarly, the combination of SEQ ID NO: 7 and SEQ ID NO: 9 amplifies a DNA fragment of 343 bp.
When the estimation accorded with the length of the DNA fragment actually amplified, the combination of primers was evaluated to accurately amplify the target nucleotide sequence in the inv A gene and marked with "+" as shown in Tables 1-1 to 1-7, whereas the combination of primers that failed to amplify the target nucleotide sequence was marked with "-" in the Tables. As obvious from Tables 1-1 to 1-7, the inv gene was accurately amplified for all the Salmonella species tested.
�Experiment 2!
To determine whether the results obtained in Experiment 1 are specific to Salmonella species having the inv A gene, the genes of clinically important enterotoxic bacteria other than Salmonella species were examined with the oligonucleotide primers of the present invention in the same manner as in Example 1.
The results are shown in Tables 2-1 to 2-12. The combinations of the oligonucleotide primers of the present invention did not amplify any nucleotide fragments derived from other enterotoxic bacterial strains nor other sources. It can therefore be concluded that the oligonucleotide primers of the present invention react with the DNAs of Salmonella species with high selectivity, thereby giving a highly reliable detection results.
While the invention has been described in detail with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
