Neisseria
Neisseria
Neisseria (pronounced: nigh-seer-ee-uh) is a genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae. Most Neisseria are not pathogenic and are part of the normal flora of the upper respiratory tract.
Etymology
The genus Neisseria is named after the German bacteriologist Albert Ludwig Sigesmund Neisser, who discovered Neisseria gonorrhoeae, the pathogen that causes gonorrhea, in 1879.
