[Demonstration of Neisseria meningitides in the urogenital tract]

The occurence of Neisseria meningitidis in the urogenital tract is a rarity but nevertheless this may lead to a false diagnosis of gonorrhea, even when the Thayer-Martin-selective-medium is used and oxidase-reaction is performed. This is demonstrated in our case. A complete diagnosis, including sugar-fermentation, is necessary, when gram-negative diplococci are isolated from urogenital swabs. In the case Neisseria meningitidis is isolated, it is not required by law to report it to the public health authorities.
