摘要

The purpose of this study was to determine survival of Toxoplasma gondii tachyzoite RH strain ingoat milk after being pasteurized in low temperature for along time. In this study vivo trial was done, i.e., usingmice that were infected with a Toxoplasma gondii tachyzoite intraperitoneally in a dose of 2.76x106.The infected mice were divided into 3 groups; (1) pasteurized milk and tachyzoite heated at a temperature of63°C for 30 minutes (T), (2) pasteurized milk and tachyzoite without being heated as a positive control (PC) and(3) pasteurized milk without tachyzoite as a negative control (NC). The results showed that tachyzoites did notdetect in the peritoneal fluid in group T and NC. However, T.gondii tachyzoites were detected in group PCwhose amount was nearly equal to the amount before and after the mice infection.
