title: [Carriers of Neisseria meningitidis among children from a primary school].
abstract: A cross-sectional and descriptive study was conducted among 318 children from the "Mártires del Corynthia" Primary School under the authorization of the Municipal Division of Education and the informed consent of their parents aimed at knowing the prevalence of meningoccoco carriers in school children, determining the epidemiological markers of the isolated strains and establishing the possible relation existing between the carrier and variables, such as age, sex, acute respiratory infection history, hacinamiento, amigdalectomy, inhibitory effect of of the accompanying flora and the secretory state of ABH antigens in saliva. All of them underwent nasopharyngeal exudate and a saliva sample was taken. In adition, the paents were surveyed about the risks factors to be investigated. 6.9 % of meningoccoco carriers were found and the NA:NT:P1:NST:L3,7,9 strains predominated. The risk factors with statistically significant results regarding the condition of carrier Neisseria meningitidis carrier were age, acute respiratory infection history, and the presence of Streptococcus pneumoniae and Neisseria lactamica of the accompanying bacterial flora in the nasopharynx of the children under study.
