On the Taxonomic Status of ‘Quin’s Oval’ Organisms Free

Abstract

Purified suspensions of the sheep rumen organism known colloquially as ‘Quin's oval’ were prepared from sheep rumen liquor. The chemical composition of cell walls prepared from the organisms of these suspensions was found to include protein, lipid and polysaccharide. A fraction from these walls, obtained after removal of much of the protein and polysaccharide, was shown to contain muramic acid, glucosamine and diaminopimelic acid. These findings are consistent with this organism being regarded as a Gram-negative bacterium.
