Neisseria meningitidis in urogenital infection.

The routine use in this department of an immunofluorescence method in the identification of suspected colonies of gonococci has led in the past 6 months to the recognition of three cases of probable urogenital tract infection with Neisseria meningitidis. In each of these cases, cultures of Gram-negative diplococci were obtained which gave weaker fluorescence with antigonococcal globulin than is usually seen with gonococci and which on further investigation proved to be meningococci.
