Probe, probe set, probe carrier, and testing method

Abstract

A probe, a set of probes, and a probe carrier on which the probe or the set of probes is immobilized, are provided for classification of fungus species. The probe or the set of probes is capable of collectively detecting fungus of the same species and distinguishingly detecting those fungus from fungus of other species. The probe is an oligonucleotide probe for detecting a pathogenic fungus DNA and includes at least one of base sequences of SEQ ID NOS. 1 to 2 and mutated sequences thereof.

1 . A probe for detecting a DNA of  Arthroderma vanbreuseghemii  which is a pathogenic fungus, comprising one of the following base sequences (1) to (5):
 (1) tctctttagtggctcaacgctgga (SEQ ID NO. 1) or a complementary sequence thereof;   (2) ggacagacgcaaaaaaattctttcagaag (SEQ ID NO. 2) or a complementary sequence thereof; and   (3) a mutated sequence which is obtained by deletion, substitution, or addition of a base on one of the sequences of SEQ ID NOS. 1 and 2 and the complementary sequences thereof within a range that the mutated sequence retains a function as the probe.   
     
     
         2 . A probe set for detecting a DNA of  Arthroderma vanbreuseghemii  which is a pathogenic fungus, comprising at least two of the following probes (A) to (P):
 (A) a probe including a base sequence represented by tctctttagtggctcaacgctgga (SEQ ID NO. 1);   (B) a probe including a base sequence represented by ggacagacgcaaaaaaattctttcagaag (SEQ ID NO. 2);   (B) a probe including a base sequence represented by tcagggatgcatttctctgcgaatc (SEQ ID NO. 2);   (C) a probe including a complementary sequence of SEQ ID NO. 1;   (D) a probe including a complementary sequence of SEQ ID NO. 2;   (E) a probe including a mutated sequence obtained by deletion, substitution or addition of a base on SEQ ID NO. 1 within a range that the mutated sequence retains a function as the probe;   (F) a probe including a mutated sequence obtained by deletion, substitution or addition of a base on SEQ ID NO. 2 within a range that the mutated sequence retains the function as the probe;   (G) a probe including a mutated sequence obtained by deletion, substitution or addition of a base on the complementary sequence of SEQ ID NO. 1 within a range that the mutated sequence retains the function as the probe;   (H) a probe including a mutated sequence obtained by deletion, substitution or addition of a base on the complementary sequence of SEQ ID NO. 2 within a range that the mutated sequence retains the function as the probe.   
     
     
         3 . A probe carrier, comprising a plurality of probes which form the probe set according to  claim 2 , wherein:
 the plurality of probes are each immobilized on a carrier; and   the plurality of probes are arranged at intervals.   
     
     
         4 . A method of detecting a DNA of  Arthroderma vanbreuseghemii  in a sample by using a probe carrier, comprising:
 (i) reacting the sample with the probe carrier according to  claim 3 ; and   (ii) detecting a reaction intensity of a probe on the probe carrier reacted with a nucleic acid contained in the sample.   
     
     
         5 . A kit for detecting a DNA of  Arthroderma vanbreuseghemii , comprising:
 the probe according to  claim 1 ; and   a reagent for detecting a reaction of a probe with a target nucleic acid.   
     
     
         6 . A kit for detecting a DNA of  Arthroderma vanbreuseghemii , comprising:
 a plurality of probes in the probe set according to  claim 2 ; and   a reagent for detecting a reaction of a probe with a target nucleic acid.   
     
     
         7 . A kit for detecting a DNA of  Arthroderma vanbreuseghemii , comprising:
 the probe carrier according to  claim 3 ; and   a reagent for detecting a reaction of a probe with a target nucleic acid.
