Control of whirling disease (Myxosoma cerebralis): Effects of drying, and disinfection with hydrated lime or chlorine

Thorough air drying of contaminated mud killed the spores of Myxosoma cerebralis. Treatment of simulated earthen ponds with hydrated lime with up to 4550 g/m² on the wet mud did not kill all of the spores. Treatment of simulated earthen ponds with up to 1200 p.p.m. chlorine did not kill all of the spores, however, treatment of contaminated water with 10 p.p.m. chlorine did kill the spores.
