Detection of streptococcus pneumoniae and immunization against streptococcus pneumoniae infection |
摘要 |
The present invention relates to oligonucleotide primers, and methods of diagnosis using the primers, wherein particular primer pairs prime the universal amplification of an amplicon specific for <i>Streptococcus pneumoniae</i> from all 90 known serotypes. The amplicon includes at least a portion of the <i>psaA</i> gene of <i>Streptococcus pneumoniae</i>. In the methods, amplification of a biological sample using the primer pairs of the invention provide an amplicon only if the sample contains a serotype of <i>Streptococcus pneumoniae</i>. The invention further relates to an isolated nucleic acid including a nucleic acid amplicon obtained using a pair of oligonucleotide primers of the invention. In still a further aspect, the invention discloses a polypeptide including an amino acid sequence encoded by a nucleic acid amplicon obtained using oligonucleotide primers. Additionally, methods of stimulating an immune response against a serotype of <i>Streptococcus pneumoniae</i> in a mammal include either administering a polypeptide encoded by a nucleic acid amplicon obtained using the pair of oligonucleotide primers of the invention, or administering a nucleic acid containing a nucleic acid amplicon obtained using the pair of oligonucleotide primers of the invention. |
