Abstract:

Some new cytoplasmic and mitochondrial (Spirostomum minus) as well as macronuclear bacteria (S. ambiguum) are recorded. The ciliate-bacteria system has high potential for investigations of endocytobiosis. New data are shown concerning antibacterial resistance of stocks of Paramecium caudatum. The results support a suggestion about food selection in this ciliate. Some possible ways of experimentally increasing the diversity of endonuclear bacteria in P. multimicronucleatum were demonstrated.
