SIMULTANEOUS DETECTION OF CHLAMYDIA PNEUlvlONIAE AND MYCOPLASMA PNEUMONIAE BY PCR

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...

Kinetics of HO 2 + HO 2 ! H 2 O 2 + O 2 : Implications for Stratospheric H

[1] The reaction HO2 + HO2 ! H2O2 + O2 (1) has been studied at 100 Torr and 222 K to 295 K. Experiments employing photolysis of Cl2/CH3OH/O2/N2 and F2/H2/O2/N2 gas mixtures to produce HO2 confirmed that methanol enhanced the observed reaction rate. At 100 Torr, zero methanol, k1 = (8.8 ± 0.9) 10 13 exp[(210 ± 26)/T] cm molecule 1 s 1 (2s uncertainties), which agrees with current recommendations...

Effect of a Mycoplasma hominis-like Mycoplasma on the infection of HEp-2 cells by the TW-183 strain of Chlamydia pneumoniae.

We isolated a Mycoplasma hominis-like mycoplasma from a stock culture of Chlamydia pneumoniae TW-183 obtained from the American Type Culture Collection and eradicated the contaminant by treating the stock suspension with a nonionic detergent, Igepal CA-630. The M. hominis-like mycoplasma neither inhibits nor enhances the infectivity of C. pneumoniae for HEp-2 cells.
