ABSTRACT:
Provided is an isolated double-stranded nucleic acid consisting essentially of the nucleotide sequences defined in the Sequence Listing by SEQ ID Nos: 5-9. These are the ITS2 sequences for C. albicans, C. parapsilosis, C. tropicalis, C. glabrata and C. krusei. A method of diagnosing systemic candidiasis in a subject is also provided. The method comprises the steps of: (a) collecting blood from the subject into tubes containing detergent, polypropylene glycol, sodium poyantholesulfonate, and sodium ethylene diamine tetraacetic acid; (b) lysing Candida cells using ZYMOLYASE.RTM.-100T with agitation; (c) extracting and precipitating the DNA from the lysed cells; (d) amplifying the precipitated DNA using universal fungal primer pairs derived from the internal transcribed spacer regions of the Candida ribosomal DNA; and (e) detecting amplified DNA from Candida by hybridizing the amplified DNA with a probe that selectively hybridizes with Candida DNA, the presence of amplified DNA indicating systemic candidiasis.
