最近报导的由嗜热脂肪杆菌芽胞与指示培养液混合制成的培基型高压蒸汽灭菌生物指示剂,能较正确地反映灭菌过程中有关温度和时间的情况,又减免了菌片法的染片、接种等步骤,为应用提供了方便。本文对培基型高压蒸汽灭菌生物指示剂的菌量、规格、保存稳定性等方面进行了观察。 Recently reported by the Bacillus stearothermophilus spores and indicator medium mixed made of Pei-based high-pressure steam sterilization biological indicators, can more accurately reflect the sterilization process temperature and time, but also relief from the bacterial law Of the dye, vaccination and other steps, to provide a convenient application. In this paper, the bacteria-based high-pressure steam sterilization biological indicators of bacteria, specifications, storage stability and other aspects were observed.
