Why is Bacillus stearothermophilus useful as an indicator of sterility?

G. Geobacillus stearothermophilus is constantly used in the biotech industry to test the success of sterilization cycles of equipment. Due to the bacteria’s high resistance to heat, it is a suitable Biological Indicator of microbe life after a sterilization cycle (read more below).Click to see full answer. Considering this, what is the purpose of sterilization indicators?Sterilization indicators, such as spore strips and indicator tape, enable routine monitoring, qualification,and load monitoring of the steam sterilization process. They indicate whether the conditions during a steam autoclave cycle were adequate to achieve a defined level of microbial inactivation.Additionally, how often should a biological indicator be put in the sterilizer? A spore test should be used on each sterilizer at least weekly. Users should follow the manufacturer’s directions for how to place the biological indicator in the sterilizer. A spore test should also be used for every load with an implantable device. Besides, why are biological indicators important? A bioindicator is a living organism that gives us an idea of the health of an ecosystem. Some organisms are very sensitive to pollution in their environment, so if pollutants are present, the organism may change its morphologyphysiology or behaviour, or it could even die.Why would a biological indicator be better than other indicators to determine if the sterilization procedure was effective?Biological indicators are generally considered the highest standard for monitoring the sterilization process. If all bacterial spores are eliminated the indicator shows the sterilization process was effective and the medical items in the sterilizer should have zero or significantly fewer microorganisms on them.
