Method of detecting heat-resistant fungus

摘要

A method of detecting a heat-resistant fungus, which has a step of identifying the heat-resistant fungus using the following nucleic acid (I) or (II):
(I) a nucleic acid including a nucleotide sequence set forth in any one of SEQ ID NOS: 24 to 35 and 83 to 86, or a complementary sequence thereof; or(II) a nucleic acid including a nucleotide sequence resulting from a deletion, substitution, or addition of one to several nucleotides in the nucleotide sequence set forth in any one of SEQ ID NOS: 24 to 35 and 83 to 86 and being capable of detecting the heat-resistant fungus, or a complementary sequence thereof.

1. A method of detecting whether a heat-resistant fungus belonging to the genus Byssochlamys is present in a sample, which comprises steps of:
(i) adding, to the sample, or adding to nucleic acid obtained from the sample, both oligonucleotide (a) and oligonucleotide (b), wherein
oligonucleotide (a) consists of a labeled or unlabeled nucleotide sequence that has 95% or more homology to SEQ ID NO: 1 andoligonucleotide (b) consists of a labeled or unlabeled nucleotide sequence that has 95% or more homology to SEQ ID NO: 2; (ii) hybridizing oligonucleotide (a) and oligonucleotide (b) to nucleic acid in the sample or to nucleic acid obtained from the sample, under conditions in which both oligonucleotide (a) and oligonucleotide (b) hybridize specifically to Byssochlamys nucleic acid that is in the sample or was obtained from the sample, or, hybridizing oligonucleotide (a) and oligonucleotide (b) to nucleic acid in the sample or to nucleic acid obtained from the sample, under conditions in which both oligonucleotide (a) and oligonucleotide (b) hybridize specifically to Byssochlamys nucleic acid that is in the sample or was obtained from the sample and performing amplification of nucleic acid using oligonucleotide (a) and oligonucleotide (b) as a primer pair for the amplification, and (iii) determining whether oligonucleotide (a) and oligonucleotide (b) hybridized to nucleic acid in step (ii), or, determining whether an amplification product was produced in step (ii), wherein determining that oligonucleotide (a) and oligonucleotide (b) hybridized to the nucleic acid, or, when gene amplification was performed, determining that an amplification product was produced by the amplification, detects the presence, in the sample, of a fungus belonging to the genus Byssochlamys.
