title: [Detection of Chlamydia pneumoniae by polymerase chain reaction].
abstract: We aimed at developing a method for early detection of Chlamydia pneumoniae (C. pneumoniae) from clinical specimens. For this purpose, we amplified C. pneumoniae-specific DNA fragments by polymerase chain reaction. A pair of 24 mer of oligonucleotides which were complementary to the sequences within the region encoding the major outer membrane were synthesized and used as primers. As the results, all three standard strains of C. pneumoniae (AR-39, TW-183 and AR-388) were identified by the detection of the amplified products of 174 base pairs, while each strain of Chlamydia trachomatis and Chlamydia psittaci and a total of 11 strains of bacteria and a strain of Mycoplasma pneumoniae were not. Thus, the present method was found to provide a very high specificity and also a high sensitivity of a detectable level of 10 x 10(-9) inclusion-forming units.
