Abstract
A region of the Trichomonas vaginalis AP65-1 gene has been identified which is useful for performing amplification assays to determine specifically whether T. vaginalis is present in the sample being tested. Oligonucleotides useful for performing thermal Strand Displacement Assay (tSDA) reactions on this gene are disclosed. The disclosed oligonucleotides can be used in an assay which is specific for multiple strains of T. vaginalis and which does not show cross reactivity with the genomes of other microorganisms or with human DNA.
Claims2
A method for detecting Trichomoniasis comprising:
- providing a biological sample;
- contacting the biological sample with a substance comprising an oligonucleotide probe set that comprises a first oligonucleotide primer comprising SEQ ID NO. 12, a second oligonucleotide primer comprising SEQ ID NO. 13 and a probe comprising SEQ ID NO. 14, wherein the oligonucleotide probe is detectably labeled and wherein the probe and primers anneal to a target gene that is SEQ ID NO:1 at the location between about base pairs 317 to 560 on the target gene;
- annealing the oligonucleotide probe set to the target gene;
- amplifying the target sequence between the two primers by a nucleic acid amplification reaction;
- and
- detecting the label as an indication of the hybridization of the probe set to the target sequence thereby indicating the presence or amount of Trichomoniasis.
