Notes
The macronucleus-specific bacterium Holospora obtusa is released from its host cell Paramecium caudatum generally after a preceding cell division. Before division, most infections forms of the bacteria can be found in a connecting strand of the dividing macronucleus. This connecting strand is deformed and finally expelled as a whole from the daughter cells. This process was observed and photographed with a simple device allowing observations for a long time under a microscope without damage to the living cells.
