Species specific antigen sequences for tick-borne relapsing fever (TBRF) and methods of use
Compositions and methods for the detection and identification of Tick-Borne Relapsing Fever Borrelia sp. antibodies.
1. A composition comprising one or more labeled and/or tagged and/or bound amino acid sequences, wherein the one or more labeled and/or tagged and/or bound amino acid sequences consist of amino acid sequences selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 11, and SEQ ID NO: 12.
2. The composition of claim 1 , wherein said amino acid sequences are bound to a substance selected from the group consisting of nitrocellulose, nylon, polyvinylidene difluoride (PVDF), magnetic beads and agarose.
3. The composition of claim 1 , wherein each of said one or more amino acid sequences are tagged with an antibody with specificity for said amino acid sequence.
4. A method of detecting antibodies to one or more of B. hermsii, B. turicatae, B. miyamotoi, B. turcica , and B. coriacae amino acid sequences in a sample from a subject suspected of having tick-borne relapsing fever (TBRF), said method comprising:
providing a biological sample obtained from a subject suspected of having TBRF;
mixing the biological sample with one or more of the labeled and/or tagged and/or bound amino acid sequences of claim 1 ; and
detecting a positive immunobinding reaction which indicates the presence of TBRF specific antibodies in the sample.
5. The method of claim 4 , wherein two or more of the labeled and/or tagged and/or bound amino acid sequences are mixed with the biological sample and a sample is considered positive for TBRF if at least two amino acid sequences are detected.
6. The method of claim 4 , wherein the labeled and/or tagged and/or bound amino acid sequences are detected with anti-human IgG or anti-human IgM antibody linked to a detectable moiety.
7. The method of claim 6 , wherein said detectable moiety is selected from the group consisting of chromophores, radioactive moieties and enzymes.
8. The method of claim 6 , wherein said detectable moiety comprises alkaline phosphatase.
9. The method of claim 6 , wherein said detectable moiety comprises biotin.
