       BACKGROUND OF THE INVENTION 
       [0004]    1. Field of the Invention 
         [0005]    DNA can be amplified from human red blood cell samples by primers designed from DNA sequences encoding a bacterial major surface protein and 16 s ribosomal RNA (16s rRNA). Primer pairs based on DNA sequences for the major surface protein 2 (MSP2) of  Ehrlichia/Anaplasma  can amplify DNA homologous to DNA from human chromosomes 1 and 7 from red blood cell samples. Primers based on DNA sequences encoding 16s rRNA from  Anaplasma  species can amplify DNA from human red blood cells, but not from nucleated white blood cells. The amplified DNA is contained in samples of red blood cells from HIV infected individuals as well as from some healthy individuals of Caucasian or African origin and represents a risk factor for HIV infection. These primers can be employed in methods for assessing risk of HIV infection by amplifying DNA from red blood cell samples. 
         [0006]    2. Description of the Related Art 
         [0007]    Chronic HIV infection causes strong immune depression (AIDS) in most patients leading to lethal opportunistic infections or cancers. Specific inhibitors of HIV multiplication are currently used for treating HIV infected patients before they reach the full-blown stage of AIDS. Such inhibitors act mostly on the reverse transcriptase and protease of HIV to efficiently suppress virus multiplication and reduce virus load to a low level of less than 40 viral RNA copies per ml of blood. Treatment results in a partial recovery of the patient&#39;s immune system as evidenced by an increase of CD4 lymphocytes and reduction of or lessened severity of opportunistic infections. However, this treatment has to be given without interruption in order to prevent rebound of virus multiplication and a subsequent reduction in the numbers of CD4 lymphocytes. Rebound of viral infection is evidence of a reservoir of HIV in infected patients that is not accessible to antiviral treatment and the existence of this reservoir is generally acknowledged. In addition to a reservoir of HIV in infected patients, such patients often carry other microorganisms that are associated with HIV infection or that cause opportunistic infections. 
         [0008]    Microorganisms associated with HIV infection that are detectable in human red blood cells, but not in human leukocytes or other kinds of nucleated human cells have not been previously characterized. The identification and characterization of microorganisms associated with HIV infection is of interest for purposes of assessing risk of HIV infection or determining the status of an HIV infected patient, for assessing risk or status of opportunistic infections, and to evaluate modes of treatment for HIV infected subjects. 
       BRIEF SUMMARY OF THE INVENTION 
       [0009]    The primers designed and discovered by the inventor provide ways to pursue these objectives. Three kinds of primers have been developed and studied by the inventor. 
         [0010]    The first kind of primer was designed based on the gene encoding the outer surface protein 2 of  Ehrlichia/Anaplasma  a genus of rickettsiales, which are known endosymbionts of other cells. These primers amplified DNA homologous to segments of DNA from human chromosomes 1 and 7. These primers are described in Appendix 2. 
         [0011]    This first kind of primers were initially designed to detect DNA encoding the major surface protein 2 (MSP2) of  Ehrlichia/Anaplasma  species. However, neither of the two pairs of primers described by Appendix 2 (Primer Pairs 1 and 2) detected at various annealing temperatures any related microorganism in the biological samples investigated. 
         [0012]    Surprisingly, it was discovered that this first kind of primer amplified DNA from human red blood cell samples that was highly homologous to DNA sequences on segments of human chromosomes 1 and 7. Primer Pairs 1 and 2 amplified DNA by the polymerase chain reaction (“PCR”) that was 100% homologous with human sequences when the primer sequences themselves were excluded. The amplified DNA was sequenced and the sequences aligned to sequences described for human chromosome 1 (clone RP11-332J14 GI:22024579, clone RP11-410C4 GI:17985906, and Build GRCh37.p5 Primary Assembly —) and in human chromosome 7 (PAC clone RP4-728H9 GI:3980548; human Build GRCh37.p5, and alternate assembly HuRef SCAF — 1103279188381:28934993-35424761). This was not expected since the primer pairs had been designed to detect genes encoding a bacterial MSP2 gene, not human chromosomal sequences. Furthermore, the amplification of such sequences from samples of red blood cells was in itself surprising since red blood cells lack a nucleus containing chromosomes. The ability to amplify DNA homologous to human DNA from red blood cells is evidence that the target DNA amplified by these primers is present as an extranuclear or cytoplasmic element, such as a plasmid, or is contained in or bound by a microorganism that invades or is otherwise associated with red blood cells. This DNA component may be present on a plasmid or otherwise contained in or bound to a microbe associated with red blood cells. Its presence represents a risk factor for HIV infection or progression and/or opportunistic infections. 
         [0013]    A second kind of primer was designed based on the sequences homologous to human chromosomes 1 and 7 that were amplified by the first kind of primers (MSP2 primers). This kind of primer is useful for identifying the target DNA homologous to human chromosomes 1 and 7 in a sample, such as a red blood cell sample. Such primers, including the first type of MSP2 primers, are used to detect risks of HIV infection, HIV progression, risks of opportunistic infections, disease prognosis and response to drug treatment in subjects where the presence of DNA homologous to segments human chromosomes 1 and 7 is a risk factor. This kind of primer is exemplified in Appendix 3. 
         [0014]    A third type of primer was developed based on the genes from  Anaplasma  species encoding 16s rRNA.  Anaplasma  is a genus of rickettsiales. This type of primer was found to amplify a sequence of 700 bp of ribosomal DNA that was about 85% identical to the corresponding genetic regions of  Rickettsia  and about 99% identical to the corresponding genetic regions of  Acinetobacter  genus.  Acinetobacter  is a genus of gram negative bacteria within the class of gammaproteobacteria. The homology of amplified 16s rDNA with  Acinetobacter  DNA may be coincidental because DNA can be amplified from biological samples that pass through a 450 nM filter unlike classical Acinetobacteria. 
         [0015]    These primers identify a bacterial agent associated with red blood cells that is related to but not identical to known  Rickettsia  species. This bacterial agent has been identified in red blood cells of not only HIV infected patients but also in some healthy individuals of Caucasian or African origin. This third type of primer is used to detect risks of HIV infection, HIV progression, risks of opportunistic infections, disease prognosis and response to drug treatment in subjects where the presence of a target containing the amplifiable 16s rRNA or 16s rDNA is a risk factor. These primers are described in Appendix 4. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0016]      FIGS. 1(A) and 1(B)  were produced on different dates. Lane numbers 1 and 2 are duplicates (from HIV-negative source) and lanes 3 and 4 are duplicates (from HIV-positive source). All DNA samples were extracted from a third passage HL60 cells exposed to an agent originating from red blood cells of HIV-negative or HIV-positive patients. These panels represent gel electrophoresis pictures of amplicons obtained by 70 cycles of PCR using primers derived from the  Ehrlichia  MSP2 gene (213 bp) and primers derived from the 16s ribosomal gene of  Anaplasma  (690 bp). The bands on the left sides of  FIGS. 1(A) and 1(B)  show the 213 bp fragment mapped to human chromosome 7 amplified by the  Ehrlichia  MSP2 primers. The bands on the right sides of  FIGS. 1(A) and 1(B)  show the 690 bp fragment amplified by the  Anaplasma  primers (SEQ ID NOS: 24 and 25). 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    Amplification of DNA from biological samples, including blood, plasma, and serum samples or samples obtained from cell culture can be performed using PCR or other nucleic amplification methods known in the art. These methods can be used to amplify or detect target DNA qualitatively or quantitatively to provide a “yes or no” determination of the presence of the target sequence or to quantitatively detect an amount of DNA amplified under controlled conditions. 
         [0018]    The DNA amplified by the first and second kinds of primers is higher frequency in red blood cells obtained from patients infected with human immunodeficiency virus compared to healthy individuals. This is especially the case for patients who have undergone or are undergoing antiretroviral therapy. The quantity of DNA amplified by these primers is reduced after long-term treatment of a patient with antibiotics and the primers were found not to amplify DNA from white blood cells or from other human cell lines. DNA has also been amplified from the red blood cells of healthy African subjects not infected with HIV using these primers. These results suggest the amplified DNA is derived from an antibiotic sensitive microorganism associated with red blood cells. 
         [0019]    Despite the apparent human origin of this DNA, the data herein show that the amplified sequences are associated with a transmissible agent and that the transmissible agent is closely associated with human immunodeficiency virus as explained below. 
         [0020]    These sequences were easily detected in the DNA of anucleated red blood cells (RBCs) in 100% (35 out of 35 subjects) HIV-infected African and Caucasian patients and they could not be detected in the DNA of nucleated cells including in the white blood cell fraction of the same patients, nor in human DNA from cultured human cells. 
         [0021]    These sequences were rarely detected in the red blood cell fraction of healthy African subjects and none were detected in the red blood cells of the healthy Caucasians tested. 
         [0022]    Long term antibiotic treatment (e.g., with doxycycline or azithromycin) of HIV-positive patients for more than three months was found to decrease the intensity of the bands amplified using these primers suggesting that these bands are induced, generated or otherwise originate from an antibiotic sensitive microorganism. 
         [0023]    Amplification of DNA from a supernatant of a short term culture of human cell line HL60 with an extract of RBC from an HIV-positive patient prepared by freeze-thawing RBC and then by removing heavy components by a low speed (10 mins at 1,500 g) centrifugation produced strong DNA bands. The intensity of these bands suggests growth and multiplication of a microorganism that contains DNA amplified by Primer Pairs 1 and 2. 
         [0024]    To further explore this effect, new primers were designed that allow amplification of regions of human genomic DNA adjacent to or including those amplified by Primer Pairs 1 and 2. These new primers include: 
         [0025]    primers “hChr1/14179308 S” upstream of, and “hChr1/14179853 AS” encompassing one end of the 237 bp amplicon related to chromosome 1 (546-bp long amplicon); 
         [0026]    primers “hChr7/4292976 S” upstream of, and “hChr7/4294619 AS” downstream of the 213 bp amplicon related to chromosome 7 (1,643-bp long amplicon); and the primers described by Appendix 3. 
         [0027]    These primers amplify DNA not only from the components of RBCs of HIV infected Caucasian or African patients, but also from the components of RBCs of healthy African subjects. However, these DNAs are lacking in all or most of HIV-negative Caucasian subjects. These sequences are amplified after antibiotic treatment of their carrier subjects indicating that the agent generating them is insensitive to antibiotic treatment. As in the case of the MSP2 primers-amplified sequences, these kinds of primer pairs amplify DNA present in or associated with anucleated RBC and not in white blood cells or human cell lines. It is possible that such a microorganism identified with these primers differs from the carrier of the initial short DNA sequences and will amplify or cause amplification of human genomic DNA sequences in an integrated or unintegrated manner. The primers disclosed herein permit the design of diagnostic tests and treatments aimed at reducing the risk of HIV infection in important segments of the human population in which this agent appears and can be detected by amplification of these DNA sequences. 
         [0028]    The third kind of primers that identify a previously unknown bacterial agent that is associated with human red blood cells and related to, but not identical to, known  Rickettsia  species are provided. These primers are derived from the 16S ribosomal DNA sequences of an  Anaplasma  species and amplify a sequence of 700 bp of ribosomal DNA that is about 89% identical to the corresponding regions of the genome of  Rickettsia . This sequence is about 99% identical to the corresponding regions of  Acinetobacter  genus DNA. Besides the primers exemplified herein, other primers that amplify the same 700 bp of ribosomal DNA or detectable fragments of this sequences may be designed based on this nucleotide sequence. These primers may amplify 20, 30, 50, 100, 200, 300, 400, 500, 600 or 700 nucleotides of this sequence. They may comprise short portions (e.g., 18-30 bp) of the 700 bp sequence and can be designed based on methods well known in the molecular biological arts. The table below depicts the various kinds of primers.

         [0029]    Specific embodiments of the invention include, but are not limited to those described below. 
         [0030]    An agent that is associated with red blood cells, especially mature anucleated red blood cells, that passes through a 0.45 micron filter. This agent may be sensitive or insensitive to a particular antibiotic. Agents sensitive to azithromycin or to a cyclin antibiotic have been identified. This agent contains, induces, excises, or otherwise provides DNA that is amplified by (i) primer pairs 1 (SEQ ID NOS: 3 and 4) or 2 (SEQ ID NOS: 5 and 6), (ii) a pair of primers described by Appendix 3 (SEQ ID NOS: 7-14 or SEQ ID NOS: 15-23), (iii), the pair of primers described in Appendix 4 (SEQ ID NOS: 24 and 25); or a pair primers that amplify at least fifteen, twenty, twenty five, thirty, forty, fifty or more consecutive nucleotides of the same DNA as is amplified by the specific primers described herein. 
         [0031]    The amplified DNA may be 80%, 85%, 90%, 95%, 99%, up to and including 100% identical or similar to human DNA, wherein sequence identity is determined by BLASTn using the default setting. Preferred parameters for determining the “nucleotide identity” when using the BLASTN program (Altschul, S. et al., Journal of Molecular Biology 215 (1990), pages 403-410) are: Expect Threshold: 10; Word size: 28; Match Score: 1; Mismatch Score: −2; Gap costs: Linear. 
         [0032]    An agent that is associated with red blood cells, passes through a 0.45 micron filter, may be sensitive or insensitive to a particular antibiotic, can be detectable in red blood cells of an HIV patient, but not detectable in the white blood cells of said patient. Such an agent may become detectable in the red blood cells of an HIV-infected patient within the first year after HIV infection or after initiation of anti-retroviral treatment. Such an agent may appear or be associated with the red blood cells of an African subject or European subject who is HIV-negative. 
         [0033]    The agent may be a microorganism, such as a bacterium, or a specific kind of bacterium such as  Rickettsia  or  Rickettsia -like bacteria,  Ehrlichia  or  Anaplasma  or a component thereof. Such an agent may contain a plasmid, episome, or extra chromosomal element comprising human chromosomal DNA that is amplified by MPS2 gene primers; or that is contained in or associated with a red blood cell that contains a plasmid or extra chromosomal element comprising human chromosomal DNA that is amplified by MPS2 gene primers. 
         [0034]    Isolated red blood cells may contain the agent as described herein as well as disrupted or lysed red blood cells, such as a supernatant produced by freezing and thawing red blood cells after removing white blood cells and then removing material that pellets by a low speed centrifugation, e.g., for 10 mins at 1,500 g. The red blood cells associated with the agent are detected by amplifying DNA from them using (i) primer pairs 1 (SEQ ID NOS: 3 and 4) or 2 (SEQ ID NOS: 5 and 6), (ii) a pair of primers described by Appendix 3 (SEQ ID NOS: 7-14 or SEQ ID NOS: 15-23), (iii), the pair of primers described in Appendix 4 (SEQ ID NOS: 24 and 25); or a pair primers that amplify at least fifteen, twenty, twenty five, thirty, forty, fifty or more consecutive nucleotides of the same DNA as is amplified by the specific primers described herein. 
         [0035]    Another aspect of the invention is the DNA amplified from the agent or from red blood cells associated with the agent. This DNA is can be produced using the primer pairs described herein. The DNA that is present in a red blood cell may be from an infectious or replicating agent per se, from a component of an infectious organism present in the anucleated red blood cell, or from DNA that results from exposure of the red blood cell or its precursor cells to an infectious or replicating agent. 
         [0036]    The amplified DNA from a red blood cell may comprise portions of human chromosome 1 or 7 including the sequences described in Appendix 5 or Appendix 6 or fragments of these sequences comprising 10, 20, 30, 40, 50, 100, 200 or more consecutive nucleotides of these sequences. 
         [0037]    The DNA according to the invention may be contained or inserted into a vector, such as a plasmid or phage vector containing the isolated or purified amplified DNA. A host cell can be transformed with the isolated or purified amplified DNA from the agent or from red blood cells associated with the agent. 
         [0038]    The invention is also directed to a method for detecting an agent as described herein comprising contacting material from anucleated red blood cells of a subject with primer Pair 1, primer Pair 2, or a pair of primers selected from the group consisting of those described in Appendix 3 under conditions suitable for amplification of DNA by said primers, and detecting said agent when amplified DNA is detected. 
         [0039]    The primers used in this method may be selected from the group consisting of (i) primer pairs 1 (SEQ ID NOS: 3 and 4) or 2 (SEQ ID NOS: 5 and 6), or (ii) a pair of primers described by Appendix 3 (SEQ ID NOS: 7-14 or SEQ ID NOS: 15-23) or a pair primers that amplify at least fifteen, twenty, twenty five, thirty, forty, fifty or more consecutive nucleotides of the same DNA as is amplified by the specific primers described herein. Alternatively, a set of primers that amplify the same DNA fragment amplified by the two primers described above may be employed. These primers may be designed by methods known in the art and each may comprise 18-30 or more base pairs of the sequence amplified by the primers above. 
         [0040]    A method for detecting an agent as described herein comprising: contacting under conditions suitable for amplification of target DNA material from red blood cells of a subject with a primer and detecting or recovering the amplified DNA, where the primers are described by Appendix 4:

         [0041]    Alternatively, a set of primers that amplify the same DNA fragment amplified by the two primers described above may be employed. These primers may be designed by methods known in the art and each may comprise 18-30 or more base pairs of the sequence amplified by the two primers above. 
         [0042]    The biological sample used in the method described above or other methods described herein may be whole blood or a cellular component of whole blood, isolated anucleated red blood cells, isolated red blood cell precursors, such as erythroblasts, bone marrow or spleen cells, or subcellular fractions thereof, such as cellular lysates, supernatants or solid materials. Blood plasma or serum or other bodily fluids or tissues may also be used as a biological sample for the methods described herein. Those of skill in the art can select an appropriate biological sample for performance of PCR or select the appropriate conditions for producing an EMS signalized sample based on the disclosures of the patent applications incorporated by reference above. Representative biological samples include whole blood, isolated RBCs, subcellular components, extracts, or lysates of RBCs or their precursor cells, blood plasma or blood serum, spinal fluid, mucosal secretions, urine, saliva, bone marrow, or tissues. 
         [0043]    A method for treating or for reducing the severity of a disease, disorder, or condition associated with the agent comprising treating a patient with an agent that reduces the titer of said agent or that reduces the amount of DNA amplified from a cell associated with it. This method may also comprise treating the patient with one or more antibiotics, such as azithromycin or a cyclin antibiotic; with one or more synthetic or natural immunostimulants, active vaccines, passive vaccines, antioxidants or antibiotics. A patient may also undergo treatment sequentially or simultaneously for viruses or other microorganisms or agents capable of causing an immunodeficient disease, disorder or condition. Treatment may be therapeutic or prophylactic and can include the administration of one or more anti-retroviral drugs or other antiretroviral treatments. The patient may be currently undergoing antiretroviral therapy or therapy to eradicate human immunodeficiency virus infection and treatment for the coinfecting bacterium initiated. Other modes of or supplemental treatments include treating the patient with one or more natural immunostimulants, antioxidants or antibiotics. The methods described herein may employ samples from subjects or patients of different geographic origins or racial or genetic backgrounds. A subject or patient may be HIV-negative, recently (e.g., less than one year) HIV-positive, a patient who has been HIV-position for more than one or two years, an HIV-positive patient who has undergone or is undergoing anti-retroviral treatments or other kinds of patients who are HIV-positive such as those with AIDS or subjects at risk of becoming HIV-positive, developing AIDS or opportunistic infections. Patients may be of African origin or may have lived in Africa and exposed to biological and environmental agents there. Similarly, a patient may be of European or Caucasian origin or may have lived in Europe or America and exposed to biological and environmental agents there. 
         [0044]    The invention is also directed to a method for treating a disease, disorder or condition associated with an agent described herein comprising contacting red blood cells with a substance that reduces the amount of DNA amplified from a red blood cell using (i) Primer Pairs 1 or 2, (ii) primers described by Appendix 3, (iii) or the primers described in Appendix 4 or primer pairs that amplify at least 20 consecutive nucleotides of the amplicons amplified by the primer pairs described above. Such a method for treating a disease, disorder or condition associated with an agent described herein may comprise contacting red blood cells of a subject with a substance that reduces the transmission of said agent to the red blood cell; may comprise replacing the red blood cells in a subject with red blood cells that are not associated with said agent or by stimulating the development of new red blood cells in said subject; or may comprise treating blood or red blood cells with an agent that that degrades, crosslinks or otherwise interferes or inactivates nucleic acids inside of or associated with a red blood cell. 
         [0045]    Another aspect of the invention is a method for screening blood for red blood cells from which DNA can be amplified using (i) primer pairs 1 (SEQ ID NOS: 3 and 4) or 2 (SEQ ID NOS: 5 and 6), (ii) a pair of primers described by Appendix 3 (SEQ ID NOS: 7-14 or SEQ ID NOS: 15-23), (iii), the pair of primers described in Appendix 4 (SEQ ID NOS: 24 and 25); or a pair primers that amplify at least fifteen, twenty, twenty five, thirty, forty, fifty or more consecutive nucleotides of the same DNA as is amplified by the specific primers described herein. This method comprises contacting a sample of blood or red blood cells with these pairs of primers and detecting amplified DNA and selecting a blood sample from which DNA was amplified or alternatively selecting a blood sample from which no DNA was amplified. For example, a blood sample from which amplified DNA is detected may be further evaluated or cultured to determine the sensitivity of the red blood cells or the agent associated with them to antibiotic or other therapeutic treatments. Alternatively, a blood sample in from which no DNA is amplified may be assessed as being free of the agent associated with the DNA amplified by these primers. 
       Example 1 
     Detection of Amplified DNA in Red Blood Cells 
       [0046]    Separation of Red Blood Cells 
         [0047]    Standard procedures for separating RBCs from buffy coat and other peripheral blood components are known. Peripheral blood was processed on a Ficoll gradient to separate the buffy coat from red blood cells. After such separation it was found that DNA extracted from buffy coat cells was completely negative as determined by PCR using the primers described above while the same primers amplified DNA in the fraction containing the separated red blood cells. While it cannot ruled out that the agent detected is externally associated with the red blood cell membranes, it was found that amplified DNA was only detected in a supernatant prepared by a low speed (1,500 g×10 mins) centrifugation to remove the heavy components of a red blood cell lysate. This lysate was prepared by repeated freeze-thawing of red blood cells isolated from the buffy coat, strong shaking by vortex, and a low speed centrifugation (1,500 g×10 mins). A pellet and supernatant fraction were obtained and tested. The primers described above only amplified DNA in the supernatant fraction, but not in the pellet. 
         [0048]    Growth on HL-60 Cells 
         [0049]    HL-60 cells are an ATCC cell line of promyelocytic origin. Samples of HL-60 cells at a density of 5×10 5  cells per ml in RPMI medium supplemented with 10% fetal calf serum were inoculated with the supernatant of the red blood cell lysate described above. This lysate was obtained from the red blood cells of HIV-positive patients after freezing, thawing and vortexing as previously described. After culturing for 3 days at 37° C. the low speed (1,500 g×10 mins) supernatants of the cultures were tested by PCR for DNA amplified using Primer Pairs 1 and 2. DNA was amplified from all of these cultures up to a dilution of 10 4 . The same results were obtained from culture supernatant that was passaged through a 0.45 micron filter. 
         [0050]    Effects of Long-Term Antibiotic Treatment 
         [0051]    Five HIV-positive patients were maintained on their antiretroviral therapy, but received for at least three months a daily antibiotic treatment (azithromycin 250 mg/day or doxycycline 100 mg/day). Blood samples were fractionated to recover a red blood cell fraction on day 0 and after 3 months of antibiotic. Results indicated that the amount of DNA amplified after 3 months of antibiotic treatment was significantly less than that amplified under the same conditions from the samples obtained on day 0. 
         [0052]    Detection of Amplified DNA in Red Blood Cells of African and Caucasian Patients 
         [0053]    Blood samples were obtained from African and European Patients who were HIV-negative or HIV-positive. Red blood cells were isolated from buffy coat and other blood components by separation on a Ficoll gradient as described above. Table 1 shows the results of amplification of red blood cell samples from these patients using Primer Pairs 1 and 2. Similar results were obtained using the primers described in Appendix 3. No DNA was amplified using Primer Pairs 3 and 4 for Chromosome 1 and 7 from the red blood cells of one European patient who was HIV-positive for a year or less. This suggests that in some Caucasians that the accumulation of this human DNA in the red blood cell fraction occurs late after infection and possibly under the selective pressure of antiretroviral treatment. However, amplified DNA was detected in this patient using the Primer Pairs 1 and 2 shown in Appendix 2, but the amplified DNA bands were weaker than those for chronically-infected HIV-positive patients.
