No. 1), AGA-GAG-CAA-CAT-GCA (Seq. Id. No. 2), ACA-GCA-GAA-GCC-GTG (Seq. Id. No. 3), CAT-AAA-TGG-CTA-CCA-GA (Seq. Id. No. 4), CAT-AAA-TGG-CTA-CCC-AG (Seq. Id. No. 5), ACT-TGG-AGT-CGA-TAG (Seq. Id. No. 6), CCA-AGG-CTT-ATA-CTC-GC (Seq. Id. No. 7), CCC-CTG-AAT-CGG-GAT (Seq. Id. No. 8), GAC-GCC-AAA-GAC-GCC (Seq. Id. No. 9), ATC-GTC-AGA-GGC-TAT-AA (Seq. Id. No. 10), TAG-CCA-GAA-GAA-AGG (Seq. Id. No. 11), CAT-AAA-TGG-CTA-GCC-AG (Seq. Id. No. 12), CTC-CGA-TGT-GAC-TGC-G (Seq. Id. No. 13), TCC-CAG-ACT-GCT-CGG (Seq. Id. No. 14), TCC-AAG-AGG-TCG-AGA (Seq. Id. No. 15), GCC-AAG-CCA-CAA-GGA (Seq. Id. No. 16), GCC-GCC-AAG-CCA-CA (Seq. Id. No. 17), GGA-CTT-GGG-GTT-AG (Seq. Id. No. 18), CCG-GGT-GCA-TTC-CA (Seq. Id. No. 19), ATG-TAG-AAC-GGA-ACT-A (Seq. Id. No. 20), GAT-TCT-CGG-CCC-CAT-G (Seq. Id. No. 21), CTG-GTT-CGC-CAA-AAA-G (Seq. Id. No. 22) and AGT-ACG-CAT-CAG-AAA (Seq. Id. No. 23).

Claims (25)

1. A PNA probe set suitable for detecting, identifying or quantitating one or more species of Candida yeast in a sample, wherein the probe set comprises PNA probes with probing nucleobase sequences consisting of: AGA-GAG-CAG-CAT-GCA (Seq. Id. No. 1), TAG-CCA-GAA-GAA-AGG (Seq. Id. No. 11), TCC-AAG-AGG-TCG-AGA (Seq. Id. No. 15), ATG-TAG-AAC-GGA-ACT-A (Seq. Id. No. 20), GAT-TCT-CGG-CCC-CAT-G (Seq. Id. No. 21), CTG-GTT-CGC-CAA-AAA-G (Seq. Id. No. 22) and AGT-ACG-CAT-CAG-AAA (Seq. Id. No. 23).

2. The probe set of claim 1 , wherein at least one probe of the set is unlabeled.

3. The probe set of claim 1 , wherein all probes of the set are unlabeled.

4. The probe set of claim 1 , wherein at least one probe is labeled with a detectable moiety.

5. The probe set of claim 4 , wherein the detectable moiety selected from the group consisting of: a dextran conjugate, a branched nucleic acid detection system, a chromophore, a fluorophore, a spin label, a radioisotope, an enzyme, a hapten, an acridinium ester and a chemiluminescent compound.

6. The probe set of claim 1 , wherein all probes of the set are labeled with one or more detectable moieties.

7. The probe set of claim 1 , wherein at least one probe of the set is labeled with at least two independently detectable moieties.

11. The probe set of claim 1 , wherein at least one probe of the set is support bound.

12. A kit suitable for performing an assay that determines the presence, absence or quantity of one or more species of Candida yeast in a sample, wherein said kit comprises: a) a combination of PNA probes, wherein the PNA probes comprise probing nucleobase sequences consisting of: AGA-GAG-CAG-CAT-GCA, (Seq. Id. No. 1), TAG-CCA-GAA-GAA-AGG, (Seq. Id. No. 11), TCC-AAG-AGG-TCG-AGA, (Seq. Id. No. 15), ATG-TAG-AAC-GGA-ACT-A, (Seq. Id. No. 20), GAT-TCT-CGG-CCC-CAT-G, (Seq. Id.
