Brachyspira hampsonii sp. nov. is a Gram-negative oxygen-tolerant anaerobe and strongly beta-hemolytic spirochete. B. hampsonii cells measure 5 to 10 μm by 0.25 to 0.38 μm, have slightly tapered ends, and have one to two flat serpentine coils. Each spirochete cell has 10 to 14 periplasmic flagella inserted at each end of the cell.
