The characterization of the rumen bacterium Eadie's oval, Magnoovum gen. nov. eadii sp. nov.

The rumen bacterium Eadie's Oval was examined by means of cell wall analysis and biochemical tests with a view to determine its taxonomic position. The purified cell walls contained components consistent with the organism being a Gram-negative bacterium, and despite its large size no abnormal cell wall constituents were found. The biochemical tests indicate that Eadie's Oval is not a member of a previously described family. The name Magnoovum gen. nov. eadii sp. nov. is proposed.
