4.3.3 Acinetobacter

Acinetobacter are non-fermenting organisms which can be differentiated from other non-fermenters such as Pseudomonas species because they are oxidase negative (Figure 9). Biochemical tests like API would be needed to confirm if necessary, but phenotypic tests to identify at species level are not very reliable and identification to species level requires specialist molecular testing. MDR isolates are best confirmed at the reference lab (Vijayakumar et al., 2019).
