W pracy przedstawiono aspekty nosicielstwa szczepów N. meningitidis w jamie nosowo-gardłowej u zdrowych uczniów szkół ponadpodstawowych oraz młodych mężczyzn w dniu wcielenia do jednostki wojskowej oraz w okresie od dwóch do sześciu miesięcy służby zasadniczej. Badania prowadzono w dwóch jednostkach wojskowych w ciągu sezonów: wiosennego 1998 oraz jesiennych 1998 i 1999.

No N. meningitidis strain was isolated from 168 children 14 years old. However, among 17-19 years old young people 14% meningococcal carriage rate was demonstrated. In three surveillance trials performed in military units in spring 1998 and autumn 1998 and 1999; 81, 225 and 153 isolates of N. meningitidis, respectively were obtained. A change in i meningitidis carrier status was observed. At the autumn study, two times more N. meningitidis intermittent carriers were found than in the spring investigations. Among these population we found short-term and long-term carriers - last day of the longest trial - 162 day. Meningococcal carriage rate increases among recruits in overcrowded living conditions.
