Host discrimination of Mycoplasma pneumoniae proteinaceous immunogens.

Host discrimination of Mycoplasma pneumoniae proteinaceous immunogens

The immune response of experimentally infected hamsters and human patients to Mycoplasma pneumoniae was examined by radioimmunoprecipation in conjunction with gel electrophoresis and fluorography. Both intrinsically and extrinsically labeled mycoplasma proteins were coincubated with acute and convalescent sera in a radioimmunoprecipitation assay. Two M. pneumoniae proteins were selectively prec...

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...

Motility of Mycoplasma pneumoniae.

Cell of Mycoplasma pneumoniae FH gliding on a glass surface in liquid medium were examined by microscopic observation and quantitatively by microcinematography (30 frames per min). Comparisons were made only within the individual experiments. The cells moved in an irregular pattern with numerous narrow bends and circles. They never changed their leading end. The average speed (without pauses) w...

Immunogenicity of Mycoplasma pneumoniae.

The immunogenicity of Mycoplasma pneumoniae for New Zealand white female rabbits was studied by using an immunization scheme which employed initial intramuscular immunization with vaccine in incomplete Freund adjuvant followed 3 weeks later by a series of five intravenous injections of fluid vaccine. Small doses of immunogen (15 to 150 mug of mycoplasmic protein per rabbit) gave rise to sera wh...
