摘要：
Isocyclidium globosum n.gen. n.sp. is a freshwater anaerobic scuticociliate with endosymbiotic methanogens and ectobiotic bacteria. It has been retrieved from anoxic water and sediments in Spain and England. The ciliate has mitochondria-like microbodies: these form a continuous sheet, lying immediately beneath the cell membrane in the posterior half of the ciliate. The endosymbiotic methanogens lie next to the microbodies. Rod-shaped bacteria attached to the external surface of the ciliate were observed only when the ciliate was obtained from sulphate-rich anoxic water. We describe the morphology, infraciliature and ultrastructure of the ciliate and its associated symbionts and other bacteria.
