Abstract:
A test based on restriction enzyme analysis identifies and differentiates strains of porcine reproductive and respiratory syndrome virus (PRRSV). Amplified cDNA from the ORF 5 region of the viral genome has been targeted for identification of unique restriction sites that allow for the differentiation of the vaccine strain from field strains, and for differentiation of field strains from each other through the use of selected restriction enzymes. This assay is useful for both clinical diagnosis of PRRSV field strains in vaccinated pigs as well as for epidemiological studies in the evaluation of the source and transmission of PRRS field viruses.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a differential test for distinguishing strains of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) from one another and for differentiating field stains from the currently used vaccine strain. 
     Porcine reproductive and respiratory syndrome (PRRS) was first reported in North America in 1987 (Keffaber, 1989) and emerged in Europe in late 1990 (Wensvoort et al., 1991). Recently, PRRS has gained world-wide attention because of its economic impact on the swine industry. The disease is characterized by reproductive failure in pregnant sows and respiratory problems in pigs of all ages (Loula, 1991). The causative agent of PRRS is a small (50-60 nm) positive-stranded RNA enveloped virus. The genome is a polyadenylated RNA molecule of about 15 kb and contains eight open reading frames (ORFs). Viral proteins are expressed by six subgenomic mRNAs which are transcribed from the negative strand using a body sequence derived from the 5&#39; end of the viral genome (Meulenberg et al., 1995). The virus replicase is most likely encoded by ORFs 1a/1b by a -1 frameshift (Conzelmann et al., 1993). Open reading frames 2 to 4 encode for putative structural proteins (Van Nieuwstadt, 1995). ORF 5 encodes for a envelope (E) glycoprotein of approximately 25 kDa. A non-glycosylated membrane (M) protein of 18 kDa is encoded by ORF 6 and the nucleocapsid (N) protein of 15 kDa is encoded by ORF 7 (Meulenberg et al., 1995; Conzelmann et al., 1993). 
     Morphologically and morphogenetically, PRRSV resembles equine arteritis virus (EAV), lactate dehydrogenase-elevating virus (LDV), and simian hemorrhagic fever virus (SHFV) (Conzelmann et al., 1993; Meulenberg et al., 1993; Plagemann and Moennig, 1991; Snijder and Spaan, 1995). As a result of common features shared by these viruses, they have been tentatively grouped into a new virus family, Arteriviridae (Conzelmann et al., 1993; Meulenberg et al., 1993, Plagemann and Moennig, 1992). 
     2. Description of the Prior Art 
     Although the clinical features of PRRS in the United States and in Europe appear similar, several recent studies have indicated phenotypic, antigenic, and genetic differences exist among PRRSV isolates (Bautista et al., 1993; Meng et al., 1994; Wensvoort et al., 1992). The amino acid sequences of ORF 2 through ORF 7 of North American isolates share only 55-79% homology with those of European descent (Meulenberg et al., 1995). It is believed that the glycosylated structural envelope protein E, encoded by ORF 5, is partially responsible for these serological variations among isolates of PRRSV (Meulenberg et al., 1995). Protein E is the counterpart of G L  of EAV (de Vries et al., 1992) and VP-3 of LDV (Gogeny et al., 1993). Both (G L  and E) proteins contain a large internal hydrophobic region which has been thought to anchor these proteins in the membrane (Meulenberg et al., 1995). The existence of neutralizing epitopes in VP-3 of LDV (Harty and Plagemann, 1988) and G L  of EAV (Balasuriya et al., 1995) was demonstrated using monoclonal antibodies and sequencing escape mutants. More recent studies indicate that protein E plays a role in inducing neutralizing antibodies (Persch et al., 1995). 
     A modified-live-virus vaccine strain RespPRRS® of PRRSV is currently used in the United States for the prevention of the respiratory facet of the syndrome. Although the vaccine strain is attenuated, it, like virulent field strains of PRRSV, has the ability to persist for at least several weeks in a vaccinated pig. Consequently, the source of PRRSV isolated from diagnostic samples is sometimes in question and it would be highly desirable to have a positive assay for identifying the source. 
     SUMMARY OF THE INVENTION 
     We have now discovered that ORF 5 can be targeted in a restriction enzyme analysis for distinguishing vaccine strain RespPRRS® of PRRSV from virulent field strains and also for distinguishing field strains from one another. The reading frame is first converted to a double stranded DNA, amplified, and then cut with restriction enzymes in conserved regions which collectively have sufficient variability among strains to permit generation of a unique fragment profile for each strain of PRRSV. 
     In accordance with this discovery, it is an object of the invention to provide a tool for distinguishing vaccine strain RespPRRS® from wild-type field strains. 
     It is also an object of the invention to provide a tool for epidemiological studies in the evaluation of the source and transmission of field strains of PRRSV. 
     It is also an object of the invention to provide a sensitive, reliable, and rapid assay for PRRSV suitable for large-scale herd screening. 
     A further object of the invention is to provide a diagnostic basis for designing an effective control program for PRRS in swine herds. 
     Other objects and advantages of this invention will become readily apparent from the ensuing description.

     DETAILED DESCRIPTION OF THE INVENTION 
     The primary points of novelty regarding the identification and distinction of individual strains of PRRSV in accordance with this invention include: (1) identification of a segment of the viral genome that is sufficiently variable among strains to allow differentiation, yet stable enough so that there is a low probability of mutational changes during repeated in vitro or in vivo passages of a particular strain; (2) selection of a universal set of primers that allows for reverse transcription (RT) and polymerase chain reaction (PCR) amplification of this segment; and (3) identification of unique restriction sites that allow for the differentiation of vaccine strains from field strains, and field strains from one another. 
     Insofar as currently known, ORF 5 is the only region of the PRRSV genome that has the proper combination of nucleotide variability among strains of PRRSV (exemplified by those listed in Table I) together with long term stability to allow for restriction enzyme differentiation. On the other hand, the stability of the ORF 5 nucleotide sequence of a particular strain is indicated (FIG. 1) by the fact that there are only two base differences (positions 38 and 451) between vaccine strain RespPRRS® (indicated in the figure as &#34;resp.PRRS&#34;), which was attenuated by repeated serial passages in cell culture, and its presumed parental strain VR 2332. These two strains (which could be considered variations of the same strain) are indistinguishable on the basis of restriction patterns associated with any of the 77 restriction enzymes reported in Table II. 
     FIG. 2 clearly depicts variations in the ORF 5 nucleotide sequences for strain RespPRRS® of PRRSV sequenced in conjunction with the invention and for 23 field strains of PRRSV, including 22 field strains sequenced in conjunction with the invention and VR 2332 (the sequence of which was previously reported in the literature). The consensus sequence for the 24 strains is also given in the figure. The position and frequency of these variations are sufficient to permit differentiation of every field strain (except presumed parental strain VR 2332) from the vaccine strain using a singular enzyme, either Mlu I or Sfc I (see Tables I and II). Assaying with both enzymes provides confirmation. As best shown in Table I, a high degree of assurance can be obtained by comparing the combined fragment patterns from Mlu I, Sfc I, Hinc II, and Sac II. All 23 of the field strains in Table I can be differentiated from one another by means of an appropriate combination of six or fewer restriction enzymes selected by reference to Table II. In Table II, the PRRSV strains are shown across the top and 77 enzymes which were evaluated for purposes of the invention are indicated on the left. The last column represents the cut sites for both strain RespPRRS® and its presumed parental strain VR 2332. Even though there are two base differences between the ORF 5 of these two strains, the cutting sites in the respective ORF 5 cDNAs are the same for all of the 77 enzymes shown in the table. The numbers shown in the table cells represent the size of the resultant fragments obtained by cutting a 716 bp amplified DNA including the ORF 5. Multiple fragment sizes are listed in order from 5&#39; to 3&#39;. The symbol &#34;xxx&#34; indicates that the particular enzyme does not cleave anywhere within the 716 bp fragment. 
     Given that the PRRSV genome is RNA, the region coding for ORF 5 must first be reverse transcribed by methods known in the art to produce double stranded cDNA. By means of PCR or any other like process, the coding region is then amplified to the extent necessary for the subsequent restriction enzyme analysis. Primers are preferably selected from nearby flanking regions upstream and downstream from the reading frame. 
     EXAMPLE 1 
     Cell and Virus Propagation 
     MARC-145 cells (Kim et al., 1993, herein incorporated by reference) were cultured in Eagle&#39;s minimum essential medium (MEM), supplemented with 5% fetal bovine serum (FES) and antibiotics. Twenty-two field stains of PRRSV isolated from Canada, Guatemala, and the United States as well as vaccine strain RespPRRS® of PRRSV were propagated and then cloned by three rounds of end point dilutions on MARC-145. 
     RNA Extraction and Reverse Transcriptase Polymerase Chain Reaction 
     Viral RNA was isolated from 22 field strains and vaccine strain RespPRRS® of PRRSV (see Table I) using a standard guanidinium isothiocyanate method (Sambrook et al., 1989, herein incorporated by reference). Single tube reverse transcriptase polymerase chain reactions (RT-PCR) as described by Sellner et al. (1992, herein incorporated by reference) with slight modifications were conducted on RNA isolated from each of the 23 strains in a Perkin-Elmer 4800®. Primers were designed based on the nucleotide sequence of field strain VR 2385 (Meng et al., 1995; Morozov et al., 1995, both herein incorporated by reference) and synthesized by Integrated DNA Technologies, Inc. (Coralville, Iowa). The sense primer was 5&#39;-CCATTCTGTTGGCAATTTGA-3&#39; (SEQ ID NO:25) and the anti-sense primer was 5&#39;-GGCATATATCATCACTGGCG-3&#39;(SEQ ID NO:26). In SEQ ID NO:27 (which is similar to SEQ ID NO:23 for ORF 5 of vaccine virus RespPRRS but additionally shows the immediate flanking regions), the sense primer extends from nucleotide 1 through nucleotide 20 and the antisense primer is the complement to the nucleotide sequence extending from nucleotide 716 to 697. A 716 bp piece encompassing ORF 5, with flanking regions of ORF 4 and ORF 6, was generated for all strains and the fragments were purified using a GENECLEAN® kit (Bio 101). 
     Sequencing 
     Double stranded nucleotide sequencing (Tabor and Richardson, 1987, herein incorporated by reference) with Taq polymerase and fluorescently labelled dideoxynucleotides (Applied Biosystems International, Prism System) as described in Sanger et al. (1977, herein incorporated by reference) was performed in triplicate on both strands for analysis with an Applied Biosystems 373A® automated sequencer. The same primer set as described above was used for sequencing. Nucleotide sequence editing and alignments were performed using Intelligenetics, GENEWORKS® version 2.2 software. 
     Analysis 
     To determine the rate of possible drift of ORF 5 sequence, four PRRSV strains of U.S. origin: NADC-8, NADC-9, 41572-2, and 18310-A were repeatedly passed on MARC-145 cells. NADC-8, NADC-9, and 41572-2 encountered 61 passages, and 18310 encountered 31 passages. RT-PCR was performed and the subsequent product was sequenced as described above. 
     Sequencing of the four selected strains passed in vitro revealed: 6 nucleotide and 4 amino acid substitutions (2,110,136,194 a.a.) for NADC-8; 2 nucleotide and 1 amino acid substitution (59 a.a.) for NADC-9; 2 nucleotide and 2 amino acid substitutions (3, 34 a.a.) for strain 41572-2; and 4 nucleotide and 2 amino acid substitutions (3,194 a.a.) for strain 18310-A (data not shown). However, none of these changes affected restriction patterns of any of these four strains. 
     Comparison of Sequences 
     The complete ORF 5 gene sequence for each of 22 PRRSV field strains and for the vaccine strain RespPRRS® was determined. The sequences for the field strains are shown in the SEQUENCE LISTING as SEQ ID NOs:1-22, that for field strain VR 2332 (previously published) is shown as SEQ ID NO:24, and that for vaccine strain RespPRRS® is shown as SEQ ID NO:23. These sequences were aligned and compared (FIG. 2) to the consensus sequence for all 24 strains. Alignment analysis indicates the same initiation and termination sites exist for all 24 strains. Regions of high and low variability are also apparent. Insertions and deletions were found to be nonexistent on the nucleotide level. 
     EXAMPLE 2 
     To differentiate the vaccine strain RespPRRS® and the presumed parental field strain VR 2332 from the 22 remaining (field) strains shown in Table I, it was necessary to select one or more appropriate restriction enzymes. The selection was based on a comparison of the ORF 5 sequence data for these strains in conjunction with the known cut sites for the enzymes as summarized in Table II. Using this technique, enzymes Mlu I, Sfc I, Hinc II and Sac II were initially selected. The enzymes Mlu I and Sfc I cut only the vaccine strain RespPRRS® and field strain VR 2332, and do not cut any of the other 22 PRRSV strains shown in Tables I and II. The restriction enzymes Hinc II and Sac II cut most of the PRRSV strains tested giving various gel patterns. Only strains 4 and 9 have a Hinc II gel pattern identical to the RespPRRS®/VR 2332 gel pattern. A second gel analysis with Sac II differentiates the vaccine strain and VR 2332 from PRRSV field strains 4 and 9. The combined results with the 4 restriction enzymes give a high degree of assurance of the RespPRRS®/VR 2332 genotype. 
     Restriction enzymes Mlu I and Sfc I are particularly valuable for differentiation because these enzymes cut only strain RespPRRS®/VR 2332 and none of the other 22 strains of PRRSV. Mlu I recognizes the 6 base pair sequence A&#39;CGCGT. For the other 22 PRRSV strains, there are two base differences, namely, guanines at positions 409 and 411; both need to occur in order to create a functional Mlu I site. Since two bases need to change for the other strains of PRRSV, the Mlu I pattern is a strong marker for the RespPRRS®/VR 2332 genotype. Also Sfc I only cuts the RespPRRS®/VR 2332 PCR-amplified DNA fragment. However, 9 of the 22 other strains of PRRSV require only a single nucleotide change, in the localized 6-nucleotide cutting site, to create a functional Sfc I site. Therefore, mutations resulting in Sfc I cutting are potentially more frequent than those for Mlu I cutting. As a safeguard against erroneous identification resulting from such mutations, it is advisable to conduct the assay with additional enzymes. 
     A typical gel electrophoresis test, in which vaccine strain RespPRRS® and strain NADC 8 are compared after digestion with Mlu I, Sfc I, Hinc II and Sac II, is represented by FIG. 3. The Mlu I and Sfc I gel patterns of strain NADC 8 are the same for all 22 PRRSV strains and distinct from strain RespPRRS®/VR 2332 gel pattern. For restriction enzymes Hinc II and Sac II, strain NADC-8 gel patterns are also distinct from strain RespPRRS®/VR 2332 patterns, but similar to other PRRSV strains. However, all of the PRRSV strains in Table II can be differentiated one from another by appropriate selection of restriction enzymes. No more than 6 restriction enzymes would be needed for differentiating the strains reported in Table II. 
     EXAMPLE 3 
     The constancy of the restriction enzyme pattern within ORF 5 during persistent infection of pigs with PRRSV was evaluated for the purpose of assessing the validity of the assay described in Example 2. Virus stability upon PRRSV replication in vivo was studied in four individual gilts, in penmates, and in gilt-piglet relationships. The results are shown in Table III, below. In each of evaluations Nos. 1-3, the virus was passaged in vivo in a gilt for a period of 7 weeks. After this time, virus was isolated from a sample taken by lung lavage wherein the alveolar macrophages, which are believed to be the primary cells for virus replication in vivo, are flushed from the lung. In each case, the recovered strain was characterized by the same RE pattern as the exposure strain (RespPRRS®). In evaluation No. 4, the same results were obtained for strain NADC-8. In evaluation Nos. 5 and 6, a pig was exposed to strain NADC-8, and 8 weeks later brought into contact with a second pig which thereafter shared the same pen. After 3 weeks, the RE pattern of the strain recovered from the second pig was identical to that of Strain NADC-8 used to infect the first pig. In evaluation No. 7, a pregnant gilt was infected with strain RespPRRS® eight weeks prior to farrowing. The RE pattern of the PRRSV recovered 5 weeks later from one of her piglets was the same as the original strain RespPRRS®. 
     It is understood that the foregoing detailed description is given merely by way of illustration and that modifications and variations may be made therein without departing from the spirit and scope of the invention.
