Morphology

Neisseriaceae

CELLULAR

Staining	Gram-negative, but the cells often have a tendency to resist Gram decolorization.
Morphology	Organisms are either coccal, occurring singly, in pairs or in masses, often with adjacent sides flattened (different planes of division), or distinctly rod shaped or coccoid (one plane of division), frequently occurring in pairs or short chains.
Motility	Flagella and swimming motility are absent. Strains of several species are fimbriated (piliated) and may show surface-bound "twitching motility".
Specialized structures	May be capsulated nonsporing

Growth Parameters

Neisseriaceae

PHYSIOLOGICAL

Tropism
Oxygen	All species grow aerobically. Strains of some species may also grow weakly under anaerobic conditions
pH
Temperature	Strains of all recognized species usually have an optimum growth temperature of about 32-36`C, butpsychophilic strains may be found in the genus Acinetobacter
Requirements	Several species have complex growth requirements while a few species grow regularly in simple defined media.
Products
Enzymes	The oxidase test is positive for all genera except Acinetobacter
Unique features

ENVIRONMENTAL

Habitat	All presently recognized oxidase-positive species are parasitic in warm-blooded hosts,while strains of Acinetobacter are much less distinctly parasitic or are not parasitic, having water and soil as their main habitat
