Definitions
- This invention relates to the field of molecular biology and more specifically to methods for molecular fingerprinting for the characterization and identification of organisms.
- microorganisms Central to the field of microbiology is the ability to positively identify microorganisms at the level of genus, species, or serotype. Correct identification is not only an essential tool in the laboratory, but it plays a significant role in the control of microbial contamination in the processing of food stuffs, the production of agricultural products, and the monitoring of environmental media, such as ground water. Of greatest concern is the detection and control of pathogenic microorganisms. Typically, pathogen identification has relied on methods for distinguishing phenotypic aspects, such as growth or motility characteristics, and for immunological and serological characteristics. Selective growth procedures and immunological methods are the traditional methods of choice for bacterial identification and these can be effective for the presumptive detection of a large number of species within a particular genus.
- Nucleic acid polymorphism provides a means to identify species, serotypes, strains, varieties, breeds, or individuals based on differences in their genetic make up. Nucleic acid polymorphism can be caused by nucleotide substitution, insertion, or deletion. The ability to determine genetic polymorphism has widespread application in areas such as genome mapping, genetic linkage studies, medical diagnosis, epidemiological studies, forensics, and agriculture. Several methods have been developed to compare homogenous segments of DNA to determine if polymorphism exists.
- PCR polymerase chain reaction
- RAPD polymorphic DNA
- APPCR arbitrarily primed PCR
- AFLP amplified fragment length polymorphism
- double stranded synthetic oligonucleotide adaptors of 10-30 bases are ligated onto the fragments generated.
- Primers are then designed based on the sequence of the adapters and the restriction site.
- pairs of restriction enzymes are used, nucleotides extending into the restriction sites are added to the 3' end of the primers such that only fragments generated due to the action of both enzymes (double cut fragments) are amplified.
- any polymorphism present at or near the restriction site will affect the binding of the primer and thus the distribution of the amplification products.
- any differences in the nucleotide sequence in the area flanked by the primers will also be detected.
- AFLP allows for the simultaneous co-amplification of multiple fragments.
- a further method is Direct Linear Analysis (DLA), which analyzes individual DNA molecules bound with sequence-specific tags (see Chan et al., Genome Res. 14:1137-46 (2004); U.S. Patent No. 6,263,286, incorporated herein by reference).
- the method is intended to identify repetitive information in DNA, which is moved past at least one station, at which labelled units of DNA interact with the station to produce a DNA-dependent impulse. Because the extended objects are similar, or preferably identical, and comprise a similar, or preferably identical, pattern of labelled units, a characteristic signature of interactions is repeated as each extended object moves past a station or a plurality of stations. This repetitive information is extracted from the overall raw data by means of an autocorrelation function and is then used to determine structural information about the DNA.
- DLA Direct Linear Analysis
- REP-PCR amplification of repetitive elements
- This technique is based on families of repetitive DNA sequences present throughout the genome of diverse bacterial species (reviewed by Versalovic et a/., Methods MoL Cell. Biol. 5:25-40 (1994)).
- Repetitive extragenic palindromic (REP) sequences are thought to play an important role in the organization of the bacterial genome. Genomic organization is believed to be shaped by selection and the differential dispersion of these elements within the genome of closely related bacterial strains can be used to discriminate between strains (see, e.g., Louws et ai, Appl. Environ. Micro. 60:2286-95 (1994)).
- REP-PCR utilizes oligonucleotide primers complementary to these repetitive sequences to amplify the variably sized DNA fragments lying between them. The resulting products are separated by electrophoresis to establish the DNA "fingerprint" for each strain.
- the output data of these fingerprinting systems generally is measured by assigning band sizes, though these assignments are somewhat imprecise depending on the sizing ladder used for the comparison.
- the output data can be difficult to compare between laboratories and often relies on the use of expensive proprietary software programs (such as BioNumerics, Applied Maths, Austin, TX) to handle the data.
- Applicants have solved the aforementioned problems by embedding the fingerprint bands from any amplification based fingerprinting method within a DNA sequence so that small differences in size are resolvable.
- Fingerprint output is provided in a text file format that can then be analyzed by powerful, freeware bioinformatics tools.
- One aspect is for a method of identifying an organism in a sample comprising: (a) providing a sample comprising said organism, said organism comprising at least one nucleic acid; (b) combining said sample or the at least one nucleic acid therefrom with an amplification mix comprising at least one labeled oligonucleotide primer; (c) generating at least one labeled amplification product from the at least one nucleic acid of said organism using a nucleotide amplification technique employing said at least one labeled oligonucleotide primer; (d) combining said at least one labeled amplification product with products of a DNA sequencing reaction to create a separation mix; and (e) separating said separation mix on the basis of oligonucleotide length in a fluorescent DNA sequencing instrument to generate a sequence embedded fingerprint pattern for said organism.
- the method comprises after step (e) the further steps of: (f) comparing said sequence embedded fingerprint pattern for said organism to a database containing sequence embedded fingerprint patterns for known organisms; and (g) identifying said organism as a function of said comparison to said database.

- oligonucleotide refers to a molecule comprised of two or more deoxyribonucleotides or ribonucleotides.
- primer refers to an oligonucleotide of any arbitrary sequence, whether occurring naturally, as in a purified restriction digest, or produced synthetically, that is capable of acting as a point of initiation of synthesis when placed under conditions in which synthesis of a primer extension product which is complementary to a nucleic acid strand is induced, i.e., in the presence of nucleotides and an agent for polymerization such as DNA polymerase and at a suitable temperature and pH. It is preferable that primers are sequences that do not form a secondary structure by base pairing with other copies of the primer or sequences that form a "hair pin" configuration. The sequence conveniently can be generated by computer or selected at random from a gene bank.
- the primer is preferably single stranded for maximum efficiency in amplification, but may alternatively be double stranded. If double stranded, the primer is first treated to separate its strands before being used to prepare extension products.
- the primer is an oligonucleotide of any arbitrary sequence,
- primers used for amplification based fingerprint methods are labelled with a fluor.
- the fingerprint amplicons are comingled with the product of a previously performed DNA sequencing reaction.
- the comingled products are then run to produce a DNA sequence from a fluorescent DNA sequencing instrument.
- the sequence output is perturbed at positions where the fingerprint products are migrating with like-sized DNA sequencing fragments. The perturbations result in an altered DNA sequence output from the instrument.
- the nucleic acids to be analyzed by a process described herein may be DNA or RNA, and the DNA or RNA may be double stranded or single stranded.
- Any source of nucleic acid, in purified or nonpurified form, can be utilized as the starting nucleic acid.

- the nucleic acid may constitute the entire nucleic acid or may be a fraction of a complex mixture of nucleic acids.
- the nucleic acid is deoxyribonucleic acid.
- Processes described herein are applicable to any nucleic acid-containing starting material, including foods and allied products, vaccines and milk infected with a virus or a bacterium, whole blood, blood serum, buffy coat, urine, feces, liquor cerebrospinalis, sperm, saliva, tissues, and cell cultures (such as mammalian cell cultures and bacterial cultures).
- the processes are also applicable to relatively pure input materials, such as the product of a PCR or the product to be purified further of another process for recovering nucleic acids.
- the step of generating an amplified nucleic acid product can be performed by, for example, RAPD PCR, AFLP PCR, REP-PCR, or DLA.
- RAPD RNA polymerase
- suitable commercially available DNA polymerase includes DNA polymerase obtained from the thermophilic bacterium Thermus aquaticus (Taq polymerase) or other thermostable polymerases. Structural variants and modified forms of this and other DNA polymerases would also be expected to be useful in the process of the present invention.
- Taq polymerase Thermus aquaticus
- RNA templates reverse transcriptase is an example of a DNA polymerase that would also be expected to be useful.
- the polymerase extends the length of the primer in the 3' direction.
- the sequence of the extension product will generally be complementary to the corresponding sequence of the template strand.
- nucleoside triphosphate substrates are employed as described in PCR Protocols, A Guide to Methods and Applications, M. A. Innis, D. H. Gelfand, J. -J. Sninsky and T. J. White, eds. pp. 3-12, Academic Press (1989), which is incorporated by reference, and U.S. Patent Nos. 4,683,195 and 4,683,202, both incorporated by reference.
- the substrates can be modified for a variety of experimental purposes in ways known to those skilled in the art. As an example, at least one of the natural nucleoside triphosphate substrates may be replaced by a mobility-shifting analogue as taught in U.S. Patent No. 4,879,214, which is incorporated by reference.
- U.S. Patent No. 4,683,202 to Mullis is directed to a process for amplifying any desired specific nucleic acid sequence contained in a nucleic acid or mixture thereof.
- the process of Mullis comprises treating separate complementary strands of the nucleic acid with a molar excess of two
- oligonucleotide primers and extending the primers to form complementary primer extension products, which act as templates for synthesizing the desired nucleic acid sequence.
- the primers of Mullis are designed to be sufficiently complementary to different strands of each specific sequence to be amplified. The steps of the reaction may be carried out stepwise or simultaneously and can be repeated as often as desired.
- At least one primer of greater than seven nucleotides is provided.
- Primers can be synthesized by standard techniques known to those skilled in the art.
- at least one primer of nine to ten nucleotides in length is employed. Conveniently, one primer is employed.
- the at least one primer is labelled, preferably with a fluorophore, which can be, for example, dR6G, dR110, dTAMRA, dROX, VIC, NED, PET, LIZ, 6-FAM, TAMRA, DyeMer488/615, DyeMer488/630, PE-TexasRed, ECD, Alexa Fluor 610RPE, FITC, Oregon Green 488, or Qdot525.

- a nucleic acid is contacted with at least one oligonucleotide primer as described herein.
- the extension product is dissociated from the complementary random nucleic acid on which it was synthesized to produce a single-stranded molecule; and the random nucleic acid segment is amplified by contacting the single-stranded extension product with a primer from above under conditions as, for example, disclosed in PCR Protocols and U.S. Patent No. 4,683,202 such that an amplification extension product is synthesized using the single strand produced (i.e., the dissociated extension product) as a template.
- the comingled products are then run to produce a DNA sequence from a fluorescent DNA sequencing instrument.
- the sequence output is perturbed at positions where the fingerprint products are migrating with like-sized DNA sequencing fragments.
- the perturbations result in an altered DNA sequence output from the instrument.
- a process disclosed herein can be used to construct a nucleic acid 'fingerprint'.
- Such fingerprints are specific to individual organisms and can be applied to problems of identification or distinguishing of individual organisms.
- Such a fingerprint would be constructed using multiple polymorphisms generated by different primers and detected by the present invention, just as the
- polymorphisms are used to create a fingerprint in Jeffreys, A. J., "Individual- Specific 'Fingerprints' of Human DNA", Nature 316:76-79 (1985), which is incorporated herein by reference. That is, genomes are compared for the presence of absence of polymorphisms.
- the steps of generating amplification products and producing an amplification profile after mixing the amplifications products with the oligonucleotide size ladder can be repeated at different stringency conditions as compared to that of a first pass through the process to generate a different amplification profile as compared to that generated by the first pass. Multiple repetitions are of course possible.
- RAPD polymorphic DNA
- each primer was present in the reaction at 0.25 ⁇ concentration in the presence of other components necessary for performing polymerase chain reaction (nucleotides, polymerase, buffer) in a total reaction volume of 30 ⁇ ; for single primer FP5, it was present in the reaction at 0.1 ⁇ concentration in a total reaction volume of 30 ⁇ , in the presence of the other components required by polymerase chain reaction.
- PCR was carried out using a 2 minute hold at 95 °C followed by 10 cycles of 15 seconds at 95 °C, 5 minutes at 40 °C and 1 minute at 70 °C, followed by 30 cycles of 95 °C for 15 seconds and 3 minutes at 70 °C.
- PCR reaction products were cleaned up as appropriate for DNA sequence reactions prior to loading on a capillary electrophoresis sequence apparatus, at which time the PCR products are recovered in a 15 ⁇ volume of H 2 0.
- a 2 ⁇ aliquot of the PCR product is then added to 20 ⁇ of deionized water.
- a commercial sequence standard (hsp 60, Applied Biosystems, Foster City, CA) is prepared as follows. A 1 ⁇ aliquot of the sequence standard is mixed with 9 ⁇ of formamide (HiDi, Applied Biosystems). 1.5 ⁇ of the diluted PCR product is then added to the 10 ⁇ sequence standard/formamide solution.
- Samples are then mixed, denatured as for a standard sequencing reaction and loaded on to an Applied Biosystems 3730 DNA sequencer and run using standard DNA sequencing conditions.
- the output sequence files are then analyzed using standard DNA sequence analysis tools.
- Clustal W alignments show that the replicate samples from a single organism cluster together and are separate from the clusters for non-identical microorganisms.
