Effect of a mushroom toxin, orellanine, on the cellular slime mold<i>Dictyostelium discoideum</i>and the bacterium<i>Escherichia coli</i>

Abstract

Orellanine, the toxic principle of Cortinarius orellanus efficiently inhibited the growth of the amoebae Dictyostelium discoideum. No significant effect on phagocytosis or pinocytosis was observed. The growth of the bacterium Escherichia coli was inhibited with a sensitivity similar to that of D. discoideum.
