| Outline of Final Research Achievements |
Detection of Streptococcus pneumoniae colonized in the pharynx of healthy carriers has relied on conventional culture methods of direct plating of pharyngeal swab specimens.The accurate measurement of the carriage of pneumococci, however, has not been necessarily achieved with these methods. A PCR-based detection method of specific lytA as well as PCR serotyping of S. pneumoniae was recently developed and their effectiveness was confirmed. We modified the reaction conditions of these methods to improve the detection rate and applied them to the detection of S. pneumoniae carried in healthy adults.The DNA template preparations were then used for PCR-based serotyping with primers specific for each of the types included in pneumococcal PPV23. We recommend PCR-based identification and serotyping of S. pneumoniae in broth enrichment culture of pharyngeal swab specimens as a reliable method for the surveillance of healthy careers with low density colonization.
