The authors describe a unique case of isolation of Neisseria meningitidis C:2a:P1.2,P1.5 in August 1997 from a 7-year-old female patient from a vaginal smear during purulent inflammation of the external genital following injury. This is the first described case of isolation of N. meningitidis from this site described in our country. The authors draw attention to the necessity to consider uncom- mon occurrences of N. meningitidis, and to examine atypical materials also under the microscope and to identify by biochemical methods all isolated Neisseriae incl. gonococci.

        Key words: Neisseria meningitidis – vaginitis – uncommon site of infection.
