Endosymblotlc bacteria have often been noticed in protozoa. In cillates they received particular attention after it was discovered that a killer-phenotype is associated frequently with them. Many are found in the cytoplasm, while some apparently have chosen the nucleus as their regular habitat. Whether they are parasites, occasional guests, symbionts from which their hosts benefit, or well-integrated elements which perform essential functions for their hosts and therefore have reached the status of a cell organelle is known for only a small fraction of them (8).
