Noun

A gram-negative aerobic non-fermenting and fastidious non-motile bacterium involved in various human diseases particularly nosocomial infections.

Supplement

Acinetobacter gerneri is a catalase positive and oxidase negative bacterium which grows at temperature of 30’C. It is isolated and mostly found in various environmental conditions including water, soil, sewage, foodstuff and human skin that has oxygen availability. Its 16S rRNA sequence consists of 1502 base pairs with a molecular weight of approximately 66 kDa which has been tested to be positive of fumarate, pyruvate and L-malate.

Acinetobacter gerneri in culture media shows colonies characterized by convex, circular and slightly opaque. It has the ability to degrade polyurethane typified by the measurement of growth, SEM observation, purification and measurement of electrophoretic mobility as well as formed chalky precipitate in liquid medium indicating cell binding to polyurethane colloidal particles.

Acinetobacter gerneri is implicated in nosocomial infections particularly to those with compromised immune system, infants and elderly.
