Morphology

Acinetobacter

CELLULAR

Staining	. Gram-negative but occasionally difficult to destain.
Morphology	Rods 0.9-1.6 um in diameter and 1.5-2.5 um in length, becoming spherical in the stationary phase of growth. They commonly occur in pairs and also in chains of variable length
Motility	Swimming motility does not occur but the cells display "twitching motility", presumably because of the presence of polar fimbriae.
Specialized structures	Do not form spores.

Growth Parameters

Acinetobacter

PHYSIOLOGICAL

Tropism	chemoorganotroph
Oxygen	Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor.
pH
Temperature	All strains grow between 20 and 30`C, with most strains having temperature optima of 33-35`C
Requirements	Grow well on all common complex media. Most strains grow in defined media containing a single carbon and energy source; they use ammonium or nitrate salts as the source of nitrogen and display no growth factor requirements. The pentoses D-ribose, D-xylose, and L-arabinose can also be utilized as carbon sources by some strains... D-glucose is the only hexose utilized by some strains
Products
Enzymes	Catalase-positive Oxidase- negative...
Unique features

ENVIRONMENTAL

Habitat	Occur naturally in soil, water and sewage
Lifestyle
Pathogenicity	Can cause nosocomial infections in humans
