【 摘 要 】

Although invasive meningococcal disease is rare in Japan (0.028 cases per 100,000 population), its incidence is 10 times greater in many other countries. Colonization is a prerequisite for invasive meningococcal disease. However, no study in Japan has involved specifically analyzing the carriage rate of Neisseria meningitidis in children. During 5 months in 2015, the respiratory tract specimens of patients who presented to 3 hospitals with respiratory symptoms were cultured. The bacteria were identified in selective media using a meningococcal detection kit and the serogroup was identified using polymerase chain reaction analysis. In 389 patients aged ≤15 years with respiratory symptoms, the N. meningitidis isolation rate was 0.26% (1/389). The serogroup of the only child who tested positive was Y. In this study, we detected a low meningococcal isolation rate in pediatric patients. Due to increasing globalization, the risk of invasive meningococcal disease is likely increasing in Japan. Accordingly, invasive meningococcal diseases should be continuously monitored in Japan. Future large-scale studies should assess meningococcal isolation rates and corresponding serogroups.
