This family includes the classical genres:
I Neisseria
II Moraxella
III Acinetobacter
IV Kingella
V Oligella
The genus Acinetobacter is attached to this family, but his characters are very different from those of otherNeisseriaceae (lack of oxidase and nitrate reductase).By cons, Branhamella and Moraxella are close genetically well as morphology differentiates. They were brought together in the same genus (Moraxella) with two sub-genres (Moraxella and Branhamella). In such Oligella newly created are linked previously designated asMoraxella strains urethralis.
This family is heterogeneous and taxonomic revisions are likely.
