Abstract：Objective To understand the epidemiological characteristics of carrier rate for Neisseria _eningitides among healthy population from 2013 to 2015 in Gaomi city, and provide a scientific basis for the prevention and control of meningococcal meningitis. Methods Using the stratified cluster sampling, total 996 throat swabs were collected from seven age groups in healthy population in the early, medium and later stage of epidemic cerebrospinal meningitis in the city. The samples were inoculated on bi-antibiotic chocolate agar plate, and Neisseria eningitides strains were separated and cultured. Staining and observating with a microscopy, biochemical identification, and serological agglutination typing were performed. Results Eight positive pharyngeal swabs were detected for Neisseria meningitides with a carrier rate 0. 80%, and the strains were identified to belong to group A, B, C and W135, with four swabs containing group A strain, accounting for 50%. The carrier rate for Neisseria eningitides was high in children aged 1 to 3 years old and aged 7 to 15 years old, accounting for 3. 42% and 2. 07% respectively. The differences in carrier rate for all age groups were statistically significant (P=0.002). The carrier rate in health population in Juchenghe Town and Mishui Street was high, accounted for 1. 81% and 1.22%, respectively, and the differences were not statistically significant in towns and streets. Conclusion The carrier rate of epidemic cerebrospinal meningitis is 0. 80% among healthy population in Gaomi, and the rate is high in children aged 1 to 3 years old and 7 to 15 years old. The major epidemic strain is group A.
