Abstract A killer strain was discovered in cellular slime molds. The wild isolate CK-8 of Polysphondylium pallidum kills all other strains in Polysphondylium and Dictyostelium, as far as could be determined, except strain CK-8 itself and its complementary mating type strain CK-9. Growth-phase cells of CK-8 excrete a killer factor which is sensitive to heat, above 60°C for 5 min, and trypsin. The apparent molecular mass of the factor was determined at 10 000–12 000.
