  • In-situ hybridization probes for the detection of microsporidial species
    Patent number: 6855498
    Abstract: The present invention provides in situ hybridization probes which include a marker and a nucleic acid molecule able to hybridize exclusively with only one species of Encephalitozoon. The nucleic acid molecule may be, for example, complimentary to segment 878-896 of 16S rRNA of Encephalitozoon hellem spores. Specifically disclosed probes are those including the following nucleotides: (1) 5?-ACT CTC ACA CTC ACT TCA G-3? (Seq. I.D. No. 1) which is species specific for Encephalitozoon hellem, (2) 5?-CAG ACC ACT ATC TGC A-3? (Seq. I.D. No. 2) which is species specific for Encephalitozoon cuniculi and (3) 5?-GTT CTC CTG CCC GCT TCA G-3? (Seq. I.D. No. 3) which is species specific for Encephalitozoon intestinalis. The assay of the present invention utilizes a sample such as surface, ground or drinking water, suspected of containing one of the aforementioned species as a target organism.

    Publication number: 20020102584
    Abstract: The present invention provides in situ hybridization probes which include a marker and a nucleic acid molecule able to hybridize exclusively with only one species of Encephalitozoon. The nucleic acid molecule may be, for example, complimentary to segment 878-896 of 16S rRNA of Encephalitozoon hellem spores. Specifically disclosed probes are those including the following nucleotides: (1) 5′-ACT CTC ACA CTC ACT TCA G-3′ (Seq. I.D. No. 1) which is species specific for Encephalitozoon hellem, (2) 5′-CAG ACC ACT ATC TGC A-3′ (Seq. I.D. No. 2) which is species specific for Encephalitozoon cuniculi and (3) 5′-GTT CTC CTG CCC GCT TCA G-3′ (Seq. I.D. No. 3) which is species specific for Encephalitozoon intestinalis.
