Neisseria meningitidis (Nm) is the pathogen carried asymptomatically in the nasopharynx but which under certain conditions can produce meningitis or even multi-organ failure. Experimental induction of meningitis in an animal model is necessary for testing new nanopharmaceutical products. Thus, the aim of the study was to establish the concentration of Nm capable of inducing the disease. We carried out 2 studies where we tested different concentrations of Nm obtained by the nephelometric and spectrophotometric methods. In the first study we included 20 BALB/c mice, and in the second 24. Local and general clinical signs, complete with body temperature values, body weight, hematological, microbiological and histopathological examination were important indicators for the assessment of the establishment of meningitis. The clinical results have pronounced depression in the first 2 days after inoculation, then the general condition will appear. The microbiological and histopathological examination indicated the presence of bacteria at the brain level and specific meningeal lesions only in the case of the second attempt, but the early mortality, requires additional testing of the bacterial concentration that induces meningites in a stable and persistent way so that treatment against the condition can be tested later.
