本文报道辐射处理对多种微生物的灭菌情况。通过枯草杆菌、蜡样杆菌和短小杆菌芽胞三菌的剂量-生存曲线的研究、D_(10)值的测定,计算出2.5×10~4Gy是一次性使用医疗用品的常规灭菌剂量。研究亦表明,通常用作微生物检查的枯草杆菌、蜡样杆菌和短小杆菌芽胞,作为生物指示菌,进行医疗用品辐照灭菌的效果监测是可行的。 This article reports the sterilization of various microorganisms by radiation treatment. The dose-survival curves of Bacillus subtilis, Bacillus cereus and Bacillus brevis were used to determine the D 10 value, and the conventional sterilization dose of 2.5 × 10 ~ 4Gy was calculated to be disposable medical supplies. The study also showed that Bacillus subtilis, Bacillus cereus and Bacillus subtilis, which are commonly used as microbiological tests, are useful as biological indicator bacteria to monitor the effectiveness of radiation sterilization of medical supplies.
