  <dc:description>&lt;p&gt;&lt;span&gt;Based on presumptive evidence of death (extrusion of polar filaments and disintegration of sporoplasm) 1.0%, 0.5%, and 0.25% calcium oxide or potassium hydroxide killed the spores of&amp;nbsp;&lt;/span&gt;&lt;span class="genus-species"&gt;Myxosoma cerebrallis&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;in vitro&lt;/i&gt;&lt;span&gt;. Chlorine at 400 ppm destroyed 36% to 90% of the spores but 13% to 37% of those in the controls perished. Calcium hydroxide, ammonium chloride, sodium borate, potassium permanganate, Roccal (alkyl dimethylbenzylammonium chloride), and copper sulfate allowed survival of 38–96% of the spores, usually not much less than the rate of survival of the controls.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;In simulated pond testing, quicklime at 380 grams or more per square meter (3360 lbs/acre) of pond bottom prevented whirling disease in rainbow trout (&lt;i&gt;&lt;span class="genus-species"&gt;Salmo gairdneri&lt;/span&gt;&lt;/i&gt;).&lt;/span&gt;&lt;/p&gt;</dc:description>
