Neisseria is a genus of bacteria, included among the proteobacteria, a large group of gram-negative forms. Neisseria are gram-negative diplococci which resemble coffee beans when viewed microscopicaly. The genus includes the species Image File history File links Neisseria_gonorrhoeae_02. ... Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms (as opposed to folk taxonomy). ...

Neisseriagonorrhoeae infections are acquired by sexual contact and usually affect the mucous membranes of the urethra in males and the endocervix and urethra in females, although the infection may disseminate to a variety of tissues.
The bacteriumNeisseria meningitidis, the meningococcus, is identical in its staining and morphological characteristics to Neisseriagonorrhoeae.
Neisseria meningitidis is usually cultivated in a peptone-blood base medium in a moist chamber containing 5-10% CO All media must be warmed to 37 degrees prior to inoculation as the organism is extremely susceptible to temperatures above or below 37 degrees.
