Effect of aflatoxin B1, ochratoxin and rubratoxin B on a protozoan,Tetrahymena pyriformis HSM


Rubratoxin B is more inhibitory to the growth ofT. pyriformis than is either aflatoxin B1 or ochratoxin. Only a marginal effect on cell respiration was exerted by these mycotoxins. The presence of the divalent ions, Mg++, Ca++ and Fe++, did not reduce the toxicity of rubratoxin B. A bioassay sensitive to 1 to 5 μg/ml rubratoxin B has been developed employingT. pyriformis.
