A novel method for isolation of Chlamydia pneumoniae by treatment with trypsin or EDTA.

چکیده
To establish a novel method for the efficient isolation of Chlamydia pneumoniae, experiments were performed to determine the effects of EDTA or trypsin treatment of C. pneumoniae on its adsorption and inclusion body formation. Treatment of C. pneumoniae with 0.1% trypsin or 1 mM EDTA significantly increased inclusion body-forming activity from 8,000- to 10,000-fold higher than that of the control. C. pneumoniae was successfully isolated in cultured cells which were inoculated with clinical specimens after treatment with 0.1% trypsin.

Both C. pneumoniae and M. pneumoniae are common causes of respiratory tract infection. At present, both are still diagnosed in the laboratory retrospectively by serology. This is despite many publications which indicate that PCR, which is not retrospective, is extremely good at detecting these organisms. We thought that a single PCR test which could detect both organisms simultaneously in a...
