Structure of cytoplasmic bacterial symbionts of chlorella-free ciliate Climacostomum virens has been investigated. It is shown that ciliates are not able to support simultaneously growth and duplication of two different symbionts--bacteria and chlorella. Cells of C. virens lost bacterial symbionts after an artificial infection with chlorella by microinjection. Competitive relationships between two endopionts are discussed.
