BACTERIA of the Mima-Herellea group were not recognized as distinct and remained undescribed until 1942, when De Bord1 suggested the name Mimeae for a new tribe of gram-negative, nonmotile organisms which resembled Neisseria morphologically, but differed in biochemical characteristics. He named the two new organisms Mima polymorpha and Herellea vaginicola.
During subsequent years, other authors reported similar organisms but gave them different names so that the situation became extremely confusing. Synonyms for bacteria in this group include "B5W,"2Bacterium anitratum,3Moraxella glucidolytica,4Achromobacter lwoffi,5 and Acinetobacter anitratum.6 Reviews of the literature are given by Rosebury in 19627 and Daly et al in 1962.8
Presumably due to the uncertain taxonomic position of these bacteria, they were not included in the seventh edition of Bergey's Manual of Determinative Bacteriology. This, combined with the confusing variety of synonyms, resulted in failure to identify this group
