Objectives: The aim of this study was to investigate the prevalence of nasopharyngeal Streptococcus pyogenes in asymptomatic school children in Afyonkarahisar, Turkey. A secondary aim was to investigate whether pharyngitis occurred among the asymptomatic carriers. Methods: The study groups included 1129 primary school children in Afyonkarahisar, Turkey. An infectious disease specialist rubbed sterile swabs over the posterior nasopharyngeal walls of the 1129 children who had no symptoms of pharyngitis. Throat swabs were cultured for bacteria which were identified using standard microbiological methods. During the one year period of control, asymptomatic carriers were monitored for developing pharyngitis. Results: Of the 1129 children 73 (6.5%) were isolated S.pyogenes. We diagnosed 4 (5.5%) cases of pharyngitis among group A streptococcal carries. Conclusion: Our data shows that S. pyogenes nasopharyngeal carriage was found 6.5% in healthy school children. We observed a low occurrence of pharyngitis among asymptomatic school children
