Considering the fundamental role played by asymptomatic Neisseria meningitidis carriers in the transmission of the meningococcal disease, it is necessary to study the issues related to the phenotypical characterization of this microorganism more deeply. With the purpose of contributing to the identification of the strains present circulating in our country, 32 strains of N. meningitidis isolated in students from a Polytechnical Institute in the Province of Ciego de Avila were classified. The identification by genus, species and serogroups was carried out by conventional methods and for the classification into sero/subtypes and immunotypes a whole-cell ELISA with Mabs was used. The antimicrobial susceptibility was studied by the agar dilution method, determining the MIC for penicillin, cloramphenicol, ciprofloxacine, sulfonamide, rifampicine and ceftriaxone. The NA:NT:P1.NST:L3,7,9 strains predominated at (22,8%). An 82% of the strains was sulfonamide resistant, and 13% showed decreased sensitivity to penicillin
