Answer

The main differential diagnostic problem presented by Acinetobacter is to differentiate colonization from infection, including other aerobic gram-negative bacilli that colonize or infect these fluids, ie, Enterobacter species, Stenotrophomonas maltophilia, Burkholderia cepacia, Pseudomonas aeruginosa, Flavobacterium meningosepticum, and Serratia marcescens.

Because Acinetobacter is predominantly a colonizing organism, the burden of proof is on the clinician to demonstrate its pathogenic role in a given situation.
