Abstract
Spores of Clostridium perfringens, type A, were given separate or sequential treatments of gamma radiation (0 to 0.7 Mrad) and/or high temperature (93 to 103 degrees C). Prior heating, sufficient to inactivate 40 to 99% of the viable spores, had no effect on the subsequent radiation inactivation rate. Prior irradiation had a sensitizing effect on subsequently heated spores. The degree of sensitization to heat, as measured by thermal inactivation rate, increased with increased radiation pretreatment dose.
摘要
对A型产气荚膜梭菌的孢子分别或依次进行γ辐射（0至0.7兆拉德）和/或高温（93至103摄氏度）处理。预先加热足以使40%至99%的活孢子失活，但对随后的辐射失活率没有影响。预先辐照对随后加热的孢子有敏化作用。通过热失活率测量的对热的敏化程度随着辐射预处理剂量的增加而增加。
