title: Effects of heating and freezing on the viability of sarcocysts of Sarcocystis levinei from cardiac tissues of buffaloes.
abstract: Dogs fed buffalo heart muscle containing sarcocysts of Sarcosystis levinei and heated at 65-75 degrees C did not shed sporocysts, whereas other dogs fed infected heart muscle heated between 40 and 60 degrees C shed sporocysts. Dogs fed infected heart muscle stored at -4 degrees C for 48 h did not shed sporocysts, but those fed similar infected tissues stored at -2 degrees C for 24 h shed sporocysts. The results indicate that sarcocysts of S. levinei are rendered noninfective by heating to 65 degrees C or by freezing at -4 degrees C.
