Technical Abstract: Quinella gen. nov. Quinella (Quin.el'la. N.L. fem. n.) is named for the pioneering ruminologist, J. I. Quin, who described it in some detail. The organism is also known as Quin's oval. It includes nonsporing, heterotrophic, mesophilic, anaerobic ovals with tumbling motility and linear tufts of flagella on one side of their cells. The genus is gram negative, and its cell wall contains a distinct outer membrane and muramic and m-diaminopimelic acids. It reproduces by binary fission, and it usually occurs as singles and pairs. It ferments a small number of carbohydrates, and it produces lactate, acetate, propionate, and CO2 as the main fermentation products and glycogen-like reserve material. The type species is Q. ovalis.
