A gram negative non-proteolytic and non-acidifying aerobic bacterium associated with various infections in human and animals.


Acinetobacter parvus has a typical small colony size of about 0.3-0.7mm in diameter with convex circular smooth and slightly opaque that contains entire margins where it grows best at temperature ranging from 30’C-35’C. In cultured media it shows good growth on acetate and ethanol as a major source of carbon and ATP.

Acinetobacter parvus characterized by the inability to oxidize D-glucose and to hydrolyze gelatin as well as utilized DL-lactate, citrate, azelate and histidine. It able to grows well on simple media and its positive utilization of acetate typified its prototrophic strains.

Acinetobacter parvus is commonly isolated from animal and human body parts particularly in the ear. It is also isolated from the blood of human which shows similar characteristics and indicates that the strains is associated with catheter related blood stream infections.
