A polymerase chain reaction (PCR) procedure was developed for detection of Chlamydia trachomatis. Two oligonucleotide primers based on sequences within the major outer membrane protein gene from C. trachomatis serovar L2 were used. A single DNA fragment was amplified, when C. trachomatis DNA was template for the PCR. No amplified product was detected in Chlamydia psittaci DNA, Chlamydia pneumoniae DNA or other bacterial DNAs. The amplified DNA fragment was detected, when DNA of greater than or equal to 10(2) C. trachomatis per reaction was used as template for the PCR. Thus, the PCR was shown to be specific for C. trachomatis and more sensitive than the enzyme immunoassays for detection of chlamydial antigen and the chlamydial rRNA:DNA probe hybridization method.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
