Abstract
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.
摘要
对不含小球藻的纤毛虫绿口藻（Climacostomum virens）的细胞质细菌共生体结构进行了研究。结果表明，纤毛虫无法同时支持两种不同共生体——细菌和小球藻的生长与繁殖。通过显微注射人工感染小球藻后，绿口藻细胞失去了细菌共生体。讨论了两种内共生体之间的竞争关系。
