Notes

The fission rate of Paramecium caudatum cells infected with the micronucleus-specific bacterium Holospora elegans was examined before and after elimination of the micronucleus. Uninfected cells, micronuleate and amicronucleate, were used as controls. Emicronucleation of Holospora elegans-infected cells causes a decrease of fission rates, as is observed after emicronucleation of uninfected cells. This is taken as an argument that infected micronuclei still serve a function for the vegetative life of P. caudatum.
