Neisseria gonorrhoeae is a non-motile, Gram-negative aerobic coccus with a typical outer membrane composed of proteins, phospholipids and lipopolysaccharide (LPS). Neisserial lipopolysaccharide has a highly branched basal oligosaccharide structure and no repeating O-antigen subunits, also referred to as lipooligosaccharide (LOS).





Neisseria gonorrhoeae is responsible for the sexually transmitted infection gonorrhoea, a type of urethritis. The infection is characterised by a purulent discharge, but asymptomatic infection is a major problem. Neisseria gonorrhoeae could also cause conjunctivitis, pharyngitis or proctitis. The infection can be treated with antibiotic effective against resistant strains.
