  • Patent number: 8043812
    Abstract: A method of detecting Streptococcus pneumoniae, which is characterized in that it comprises amplifying a lytA gene derived from S. pneumoniae using a LAMP primer set comprising at least one primer having a nucleotide sequence that is identical to or complementary to a partial sequence in the region ranging from bp 40 to 450 of the nucleotide sequence region of the above-described lytA gene, and then detecting the obtained amplified product.

  • Patent number: 7888014
    Abstract: The present invention provides a method of detecting Haemophilus influenzae, which enables accurate and rapid detection of H. influenzae, a primer set for detecting H. influenzae, and a kit for detecting H. influenzae. Nucleic acid amplification is carried out using the DNA of H. influenzae as a template, and also using the LAMP primers as shown in SEQ ID NOS: 1 to 5 given as examples of the present invention. Thus, the presence or absence of the amplified product is detected. When primers having sequences that are complementary to the sequences as shown in SEQ ID NOS: 1 to 5 are used, such primers are excellent in terms of detection sensitivity and promptness of detection, as well as specificity. In addition, as another example of the present invention, nucleic acid amplification is carried out using LAMP primers as shown in SEQ ID NOS: 43 to 47, and the presence or absence of the amplified product is detected. Thereby, H.

  • Publication number: 20090286239
    Abstract: The present invention provides a method of rapidly, simply and accurately detecting capsular serotype Haemophilus influenzae other than Haemophilus influenzae Type b, a primer set for detecting the same, and a kit for detecting the same. The method of detecting Haemophilus influenzae Types a, c, d, e and f of the present invention comprises: amplifying capsulation locus region II derived from each of Haemophilus influenzae Types a, c, d, e and f, using a LAMP primer set comprising one or more types of primers each having a nucleotide sequence that is identical to or complementary to a partial sequence in the nucleotide sequence region of the capsulation locus region II; and detecting the obtained amplification product.
