[Growth of "Dictyostelium discoideum" on different species of bacteria (author's transl)].

Dictyostelium discoideum (Acrasida) is a predatory amoeba feeding on bacteria of forest soil. Growth of D. discoideum on various bacterial species has been studied. The majority of the species of bacteria tested provide a convenient food source of D. discoideum. However, some species of bacteria do not permit growth of these amoebae; in some cases the reason of this unability has been established: it is due either to the incapacity for amoebae to phagoycte the bacteria or to the bacterial elaboration of compounds toxic for the amoebae.
