neisseria (medicine)


Neisseria
<bacteria> Gram-negative nonmotile pyogenic cocci. Two species are serious pathogens, Neisseria meningitidis (see meningitis) and Neisseria gonorrhoeae.

The latter associates specifically with urinogenital epithelium through surface pili. Both species seem to evade the normal consequences of attack by phagocytes.
